Mobile App Development Services Users Actually Keep
Most apps are deleted within days of being installed. Yours does not have to be one of them.
Fivet Solutions LLC builds iOS and Android apps from first sketch to App Store approval: product discovery, UX design, cross-platform or native development, real-device QA, store submission, and the maintenance that keeps the app alive after launch. Based in Austin, TX, shipping since 2017.
The difference between an app that becomes part of a customer's day and one that dies on the third home screen is rarely luck. It is scoping, design discipline, testing, and a launch that treats the app stores as marketing channels.

Our app development is built for
The fundamentals
What Are Mobile App Development Services?
Mobile app development services are professional services that plan, design, build, test, launch, and maintain software applications for smartphones and tablets, most commonly for Apple's iOS and Google's Android platforms. A complete service covers product strategy, UX/UI design, frontend and backend engineering, quality assurance, App Store and Google Play submission, and post-launch updates.
An app is not a website squeezed into a smaller screen. It lives on the most personal device your customer owns and gets judged in seconds. When it earns its home-screen slot, it delivers what a mobile site cannot: push notifications, offline access, camera and location features, and one-tap payments.
When it fails to earn that slot, the cost is concrete. The booking that never happened because the form crashed at the payment step. The loyalty program abandoned because signing in took four attempts. The field technician back on paper forms because the internal app could not work without a signal. Every one of those moments was decided months earlier, in scoping, design, and QA.
Because Fivet Solutions is a full digital agency, your app is built as part of an acquisition system rather than in isolation. It shares brand, backend, and data with your website development project, and after launch it plugs into the same measurement discipline that drives our monthly SEO service: what changed, what worked, what ships next.
Every screen your users touch is designed, prototyped, and approved before development begins.
Two platforms, one product
iOS and Android App Development
iOS and Android are the two mobile platforms that matter, and a serious app strategy accounts for both. They differ in devices, design conventions, store review rules, and user behavior, which is why an app that respects each platform outperforms one that treats them as interchangeable.
iOS App Development
Apple App Store · Swift, SwiftUI
iOS app development is the process of building applications for iPhone and iPad that are distributed through the Apple App Store. Apple users tend to update their devices quickly and spend more inside apps, which makes iOS the priority platform for many subscription and premium products.
- Interfaces following Apple's Human Interface Guidelines, so the app feels native, not ported
- App Review preparation: privacy declarations, purchase rules, and the rejections first-timers hit
- TestFlight beta distribution for testing builds before public release
- Face ID, Apple Pay, push notifications, widgets, and offline storage
Android App Development
Google Play · Kotlin, Jetpack Compose
Android app development is the process of building applications for the Android ecosystem, distributed primarily through Google Play. Android holds the larger global device share and covers an enormous range of screen sizes and hardware, which makes disciplined testing essential.
- Material Design layouts that adapt across thousands of device and screen combinations
- Google Play Console management: listings, data-safety declarations, and staged rollouts
- Performance tuned for mid-range hardware, because most Android users are not on a flagship
- Google Pay, maps, notifications, and background services within Android's battery and permission rules
Most of our clients launch on both platforms simultaneously from a single cross-platform codebase. When budget or audience data argues for it, launching on one store first and following on the second after validation is a legitimate strategy, and we will tell you honestly which order fits your market.
The build decision
Native vs Cross-Platform App Development
Native development builds a separate app for each platform in its own language (Swift for iOS, Kotlin for Android), while cross-platform development uses a framework such as React Native or Flutter to ship both apps from one shared codebase. This single decision shapes your budget, timeline, and maintenance costs more than any other, so it deserves a clear-eyed comparison rather than a developer's personal preference.
Our honest default
For most business apps we recommend cross-platform with React Native or Flutter, because one codebase reaching both stores at roughly half the build and maintenance cost is the right trade for booking tools, commerce, content, and service apps. We recommend fully native builds when the product genuinely needs them, and we will explain the reasoning in plain language either way.
The cost of choosing wrong
Choosing native when cross-platform would have served means paying twice for every feature, forever. Choosing cross-platform for a product that needed deep native capability means fighting the framework late in the project, when changes are most expensive. Discovery exists to make this call with evidence, before the budget is committed.
How it works
Our App Development Process, From Idea to App Store
Our app development process is a six-stage lifecycle: discovery, UX/UI design, development, quality assurance, launch, and post-launch growth. Week ranges below are typical for a focused product and are illustrative; your fixed timeline is set during discovery. What never changes is visibility: you see installable builds on your own phone every two weeks, not a reveal at the end.
Discovery and product strategy
Weeks 1 to 2We define who the app is for, the two or three jobs it must do brilliantly, and the smallest version that proves value. Most failed app projects die here, not in the code: scoped as everything for everyone, out of budget before anyone could use them.
- Feature list ranked by user value
- Platform and stack recommendation
- Fixed scope, fixed quote, and milestone plan
User flows, wireframes, and clickable prototype
Weeks 2 to 5We map every screen between opening the app and completing its core action, design the interface, and turn it into a clickable Figma prototype you approve on your own phone. Changing a prototype costs minutes; changing a shipped app costs sprints.
- User-flow maps for core journeys
- High-fidelity screen designs
- Clickable prototype for stakeholder sign-off
Frontend, backend, and integrations
Weeks 5 to 12Development runs in two-week sprints with installable builds on your own device at the end of each one. Frontend, backend and APIs, and integrations such as payments and push notifications come together visibly instead of disappearing into a six-month black box.
- Sprint builds on your device every two weeks
- Secure backend, database, and APIs
- Payment, notification, and system integrations
Testing across real devices and OS versions
Weeks 11 to 13We test on physical iPhones and Android devices across screen sizes and OS versions, combining automated suites with manual QA. Your first one-star review should never be a crash report we could have caught.
- Device and OS compatibility matrix
- Automated plus manual test passes
- Crash, performance, and edge-case fixes
App Store and Google Play submission
Week 13 to 14We manage the full submission to both stores: listings, screenshots, keyword metadata, privacy declarations, and the review back-and-forth. Store review regularly bounces first-time submitters, so we treat launch as a deliverable, not an afterthought.
- Complete store listings for both stores
- App Review and Play review management
- Coordinated public release
Monitoring, updates, and growth
OngoingWe monitor crashes and performance, ship compatibility updates as iOS and Android evolve, and build the next features on a prioritized roadmap, while App Store Optimization works on the metric that matters: the right users finding, installing, and keeping the app.
- Crash and performance monitoring
- OS-compatibility and security updates
- Feature roadmap and ASO iteration

What Our Mobile App Development Services Include
A complete mobile app development engagement includes strategy, design, engineering, testing, launch, and growth handled by one accountable team. That matters because app projects most often stall in the seams between vendors: the designer blames the developer, the developer blames the backend contractor, and the founder pays for the arguing.
Product discovery and scoping
Workshops that turn an idea into a ranked feature list, a platform recommendation, and a fixed scope. You know exactly what is being built, in what order, and for what price before development starts.
UI/UX design and prototyping
Modern, intuitive interfaces designed around real user flows and validated with clickable prototypes. Usability problems get fixed on the drawing board, where they are cheap.
iOS and Android development
Cross-platform builds with React Native or Flutter that ship native-quality apps to both stores from one codebase, or fully native Swift and Kotlin when the product demands it.
Backend and API development
Secure, scalable backends with authentication, databases, and REST or GraphQL APIs on infrastructure such as Node.js, Firebase, Supabase, and AWS, built to stay fast as your user base grows.
Integrations
Stripe, Apple Pay, and Google Pay for payments, plus push notifications, maps, analytics, social login, and connections to the CRM or business systems you already run.
Testing and QA
Automated tests plus manual QA on real devices across screen sizes and OS versions, so crashes and edge cases are found by our team instead of your customers.
Store launch management
The full Apple App Store and Google Play submission handled for you: listings, screenshots, metadata, privacy declarations, and the review process through to approval.
Post-launch support and ASO
Crash monitoring, OS-compatibility updates, security patches, new feature development, and App Store Optimization that keeps qualified installs growing after launch day.
Your proposal documents exactly which of these are in scope before work begins, so "app development" never turns out to mean "code only, everything else is extra" halfway through the project.
The retention problem
What Makes Users Delete an App
Users delete apps for predictable, preventable reasons: crashes, slow startups, forced signups, notification spam, confusing navigation, and resource drain. Getting an install is the cheap part; keeping the home-screen slot is the product. We design and test against every failure below explicitly.
It crashes in the first session
The app freezes on its own loading screen at first open. There is no second chance: the delete takes seconds and a one-star review often follows. Device-matrix QA exists to prevent exactly this moment.
Forced signup before any value
An account, email verification, and password demanded before a single useful screen. Users who have not yet seen why the app matters will not pay for it with their data first.
A nine-second cold start
The booking a customer meant to make in the elevator gets abandoned, and the app slides to the last home screen, then off the phone. Startup speed is a retention feature, not a vanity metric.
Notification spam
Three promotional pushes a day teaches one behavior: mute, then delete. Notifications should mark moments users genuinely care about, an order shipping or a booking confirmed, or not fire at all.
Navigation that needs a manual
If users cannot reach the one thing they installed the app for within a few taps, they will not study it, they will delete it. We prototype and test core flows before development, not after launch.
Battery and data drain
Phones report exactly which apps consume the most battery and background data. An app that engineers itself onto that list gets removed in the same settings screen that exposed it.
Permission overreach
A flashlight app that wants your contacts gets deleted on principle. Every permission request must be obviously connected to a feature the user just tried to use.
No updates for a year
A stale app breaks quietly: a new OS ships, a payment SDK is deprecated, a screen renders wrong. Users read an abandoned update history as a warning label.
Getting found
App Store Optimization and Your App-Plus-Web Ecosystem
App Store Optimization (ASO) is the practice of improving an app's visibility and install conversion inside the Apple App Store and Google Play through its name, keywords, screenshots, description, ratings, and release cadence. It is search engine optimization for the two search engines your app actually lives in, and skipping it is how technically excellent apps launch to silence.
The ASO checklist we launch with
Every launch ships against this list, then iterates on it as store data comes in:
- App name and subtitle include the keyword users actually search, not just the brand name
- The first two screenshots communicate the core value without requiring a tap
- An app preview video demonstrates the primary flow in under 30 seconds
- The first three lines of the description sell the outcome, before the fold hides the rest
- Keyword metadata is researched like SEO keywords: demand, relevance, and competition
- The category is chosen for ranking opportunity, not just literal fit
- Rating prompts appear after success moments, such as a completed booking, never after a crash
- Reviews get responses, because replies are visible to every future prospect reading them
- The icon is tested for legibility at home-screen size against category competitors
- Listings are localized where the audience justifies it
- Updates ship regularly, because a recent version history signals a living product
- Crash-free rate and ratings are monitored, since store algorithms weigh quality signals
The app does not work alone
Most app installs start outside the app stores: a customer searches Google, lands on your website, and meets the app there. We treat both as one funnel: a fast site built through our website development service, made discoverable through technical SEO, feeding visitors to store listings the ASO work has sharpened.
For local businesses the loop closes tighter: a customer finds you through local SEO or your Google Business Profile, books through the app, and gets a review prompt after a great visit. Paid installs through Google Ads then scale what the organic funnel has proven.
An honest limit
Nobody controls store rankings, and we will never promise a chart position or a download count. What we control is the quality of the product, the completeness of the listing, and the discipline of iteration, the inputs that store algorithms consistently reward.
Maintenance and updates: why launch is the midpoint
App maintenance is the ongoing work of keeping an app compatible, secure, stable, and improving after its public release. Apple and Google each ship major OS versions yearly and enforce minimum SDK requirements over time, so an app left untouched does not stay the same, it quietly degrades until a store policy or a new device breaks it in public.
OS compatibility updates
Apple and Google ship major OS versions yearly, deprecate older APIs, and enforce minimum SDK levels in their stores. An app never rebuilt against current SDKs eventually fails store requirements or breaks on new devices.
Security patches
Payment SDKs, authentication libraries, and backend dependencies receive security fixes continuously. Applying them promptly protects your users' data, and it is far cheaper than responding to an incident.
Crash and performance monitoring
Tools such as Firebase Crashlytics report crashes from real devices in the field, so a bug affecting one Android manufacturer's devices gets fixed in days, not discovered months later in a review.
Feature iteration
Analytics show which screens users love and where they drop off, so post-launch budget goes to the features usage data asks for, not the ones that merely sounded good in a meeting.

How Much Does Mobile App Development Cost?
Mobile app development cost is determined by the number of platforms, feature and screen count, backend complexity, integrations, design fidelity, and compliance requirements, which is why honest quotes follow discovery rather than a contact form. Two apps that sound identical in a sentence can differ several times over in build effort once payments, scheduling, and offline support enter the scope.
The factors that move the price
Illustrative budget bands
The bands below are illustrative context for planning, not a Fivet Solutions price list. Your actual quote is fixed after a free scoping consultation and reflects your product's real scope.
Focused MVP
Low five figures (illustrative)
One core job done brilliantly: a booking tool, an ordering app, or an internal field app. Cross-platform build, essential backend, store launch.
Full-featured product
Mid five figures (illustrative)
Accounts, payments, notifications, several integrations, an admin panel, and a custom backend. The typical customer-facing business app.
Complex platform
Upper five to six figures (illustrative)
Marketplaces, real-time features, heavy compliance, or large multi-role systems where the backend is a product of its own.
How app pricing works at Fivet
Every app is quoted individually after a free discovery consultation, because the factors above can move the cost of the same idea by multiples. Your proposal defines a fixed scope, a milestone-based payment schedule tied to working deliverables rather than time passed, and a post-launch maintenance plan scoped to what the app actually needs. The quote is fixed once the scope is approved.
The most expensive app is not the one with the biggest quote. It is the one scoped without discipline, built without milestones, and abandoned at eighty percent complete. A fixed scope with a ranked feature list protects the budget better than any hourly rate ever will.

How Long Does App Development Take?
A focused MVP typically takes around 12 to 16 weeks from kickoff to public availability on both stores; larger products take longer. The phase durations below are illustrative, and your fixed milestones are set in discovery. Beware of two extremes: "your app in two weeks" usually means a template with your logo on it, and an open-ended timeline usually means an open-ended invoice.
Store review adds its own variable: Apple and Google each review every submission, and first-time rejections over privacy declarations or payment rules are common when submissions are handled casually. We plan the review round-trip into the schedule instead of discovering it at the finish line.
Choosing your path
DIY App Builders vs a Development Agency
No-code app builders assemble apps from prefabricated blocks for a monthly fee, while an agency designs and engineers a custom product you own outright. Both are legitimate tools; the mistake is using the wrong one for the stakes involved. Here is the comparison we walk prospects through, including when we tell them not to hire us yet.
Red flags when hiring an app developer
Bad app development engagements announce themselves early, if you know the signals. Walk carefully when you see:
Questions to ask before signing anything
The answers reveal what the engagement will actually feel like after the deposit clears:
- Can I install and use apps you have shipped, today, from the public stores?
- Who owns the source code, store accounts, and backend when the project ends?
- What is the fixed scope, and what happens when I request something outside it?
- Which devices and OS versions will you test on before launch?
- Who handles App Store and Google Play submission, and the rejections if they come?
- What does maintenance cost after launch, and what does it include?
- How will I see progress: sprint builds on my phone, or a demo at the end?
- What would you cut from my idea to ship a stronger first version?
We answer every one of these in writing during scoping, before any payment.
Who we build for
App Development for Austin Businesses and Beyond
We build apps for the business models where a home-screen presence changes the economics: repeat bookings, loyalty, field operations, and products where speed of access is the product. Being based in Austin means many of those clients are local, from Round Rock trades to South Congress restaurants, and our app development Austin page covers what working with a local team looks like.
Home services and trades
Booking, dispatch, and job-tracking apps for plumbing, HVAC, and remodeling companies across the Austin metro. A technician app that syncs job photos and signatures beats a clipboard in the truck.
Restaurants and food brands
Ordering, loyalty, and pickup apps that keep margins out of third-party marketplace fees. Austin's food scene runs on repeat customers; a loyalty app keeps the relationship yours.
Fitness, wellness, and studios
Class booking, membership, and schedule apps. Push notifications that fill tomorrow's half-empty class beat a mass email nobody opens.
Real estate and property
Listing browsers, tenant portals, and maintenance-request apps. In a market as fast as Central Texas, the agent whose app pushes a new listing first wins the showing.
Logistics and field teams
Internal apps for crews and drivers: routing, proof of delivery, inspections, and offline capture that syncs when a truck returns to coverage.
Startups and SaaS
MVPs scoped to prove a thesis to users and investors without burning the seed round, then a roadmap that grows the product as traction arrives.
Key Takeaways
- Mobile app development services cover the full lifecycle: discovery, UX/UI design, development, QA, store launch, and ongoing maintenance.
- Cross-platform frameworks such as React Native and Flutter serve most business apps well; fully native Swift and Kotlin builds are for products that genuinely need them.
- Most app projects fail in scoping, not coding: the strongest first version does two or three jobs brilliantly.
- App cost is driven by platforms, features, backend complexity, and integrations. Any serious quote follows discovery, not a contact-form guess.
- Launch is the midpoint, not the finish line: OS updates, security patches, and App Store Optimization decide whether the app is still thriving a year later.
- You should own everything: source code, store accounts, and backend. Walk away from any arrangement where you would not.
FAQ
Mobile App Development, Answered
How much does mobile app development cost?
Mobile app development cost depends on platforms, features, backend complexity, design fidelity, and integrations. As illustrative context, a focused MVP often lands in the low five figures, while feature-rich products with custom backends cost more. Fivet Solutions provides a fixed quote with milestones after a free scoping consultation, so the price reflects your actual product rather than a generic guess.
How long does it take to build a mobile app?
A focused MVP typically takes around 12 to 16 weeks from kickoff to store launch, covering discovery, design, development sprints, QA, and store review. Larger apps with custom backends and many integrations take longer. We define the timeline with milestones during discovery, and you receive installable builds every two weeks so progress is visible on your own phone.
Should I build a native app or a cross-platform app?
Cross-platform frameworks such as React Native and Flutter are the right choice for most business apps: one codebase ships native-quality experiences to both iOS and Android at roughly half the cost of two native builds. Fully native Swift or Kotlin development makes sense for games, heavy real-time graphics, or products built around one platform's deepest hardware features. We recommend based on your product, not our preference.
Do you develop for both iOS and Android?
Yes. We build for the Apple App Store and Google Play, usually from a single cross-platform codebase so both launch together. When a client's audience is heavily concentrated on one platform, we can launch there first and follow on the second platform once the product is validated, which stretches an early budget further.
Who owns the app and the source code?
You do. On final payment you receive full ownership of the source code, the App Store and Google Play accounts, the backend, and all project assets, along with documentation a future team could pick up. We believe an agency should be retained because it keeps delivering, never because it holds your product hostage.
Do you handle App Store and Google Play submission?
Yes. We manage the complete submission for both stores: listings, screenshots, preview media, keyword metadata, privacy and data-safety declarations, and the review process itself. Store review regularly rejects first-time submitters over privacy declarations, payment rules, or metadata issues, so we treat launch as a managed deliverable rather than an afterthought.
What is App Store Optimization and do I need it?
App Store Optimization (ASO) is the practice of improving an app's visibility and conversion inside the Apple App Store and Google Play through its name, keywords, screenshots, description, ratings, and update cadence. If nobody finds the app, its quality never gets a chance to matter, so yes: we build ASO fundamentals into every launch and iterate on them afterward.
What happens after the app launches?
After launch we monitor crashes and performance, ship compatibility updates as iOS and Android release new versions, patch security dependencies, and build new features on a roadmap informed by real usage analytics. Both stores enforce minimum SDK and API requirements over time, so an unmaintained app eventually breaks or falls out of compliance. Maintenance plans are quoted alongside the build.
Can you build the backend and integrate with our existing systems?
Yes. We build secure, scalable backends with authentication, databases, and APIs, and we integrate with the systems your business already runs: payment providers such as Stripe, Apple Pay, and Google Pay, CRMs, booking systems, and internal tools. Every integration is tested end to end on real devices before launch.
Do I need a mobile app or is a website enough?
A website is usually the right first investment: it is discoverable in search and reaches everyone. An app earns its place when users return frequently, need push notifications, work offline, or use device features such as the camera and location. Many of our Austin clients run both, and we build them as one connected ecosystem rather than two disconnected projects.
Can you take over or rescue an existing app?
Often, yes. We start with a code and infrastructure audit to assess what exists, what is salvageable, and what it would cost to stabilize versus rebuild. Sometimes the honest answer is that a rebuild on a maintainable stack is cheaper than resuscitating the old codebase, and we will tell you which case yours is before you spend anything on either.
What is an MVP and why do you recommend starting with one?
An MVP, or minimum viable product, is the smallest version of your app that delivers its core value to real users. Starting with an MVP gets the product into the market months sooner and lets actual usage data, rather than assumptions, decide what gets built next. The most expensive app is the fully featured one nobody validated.
Do you work with businesses outside Austin?
Yes. Fivet Solutions is based in Austin, TX, and serves clients across the United States and internationally. Discovery workshops, sprint reviews, and launch coordination run smoothly over video, and every client receives the same installable sprint builds regardless of location.
Your App Should Not Be a Gamble
Before we write a line of code, you will know three things:
That is how Fivet Solutions LLC has approached development work from Austin since 2017. Bring us the idea, the half-built project, or the app that needs rescuing, and we will tell you honestly what it takes, including when the honest answer is to start smaller.
