What mobile app development actually involves
Mobile app development is the work of designing, building, testing and releasing software that runs on iOS and Android phones. The app itself is only part of it. A working product also needs a backend for the data, an admin panel for your team, payments, notifications, analytics, store listings and a plan for what happens when Apple or Google changes the rules.
Most quotes go wrong because they price the app and forget the rest. We price all of it, once, after a week of discovery.
What ships with every app we build
Concretely, that means sign-in that works with the accounts your users already have, payments with real refund and failure handling, push notifications that respect quiet hours, offline behaviour for the moments the network drops, analytics wired to the questions you will ask in month two, and crash monitoring that tells us about a problem before your users do.
iOS, Android or both?
For consumer apps in India the honest answer is usually both. Android carries the volume; iOS often carries the paying users. Cross-platform frameworks make that affordable, which is why most projects we take on ship to both stores from one codebase.
| Your situation | What we usually recommend |
|---|---|
| Consumer app, general audience | Both platforms, one Flutter or React Native codebase |
| Team or field app on company devices | The one platform those devices run |
| Heavy graphics, deep hardware use, watch or widget features | Native Swift and Kotlin |
| Existing React web team and a shared codebase | React Native |
| Tight budget, needs to look identical on both | Flutter |
We wrote the longer version of this decision in Flutter vs React Native vs native, including what people get wrong about cost.
Our mobile app development process
- Discovery, week 1. We map the users, the screens, the integrations and the risks with you, then write it down. You get a fixed scope and a fixed price before anyone writes code.
- Design, weeks 2 to 3. Flows first, then screens, then a clickable prototype you can put in front of real users. Changing a screen here costs minutes. Changing it in week nine costs days.
- Build, weeks 4 to 12. Weekly demos of working software on real devices, not screenshots. We build the riskiest piece first, whether that is the payment flow, the offline sync or an integration nobody has documentation for.
- Test, throughout. Automated tests plus real devices, because an app that works on the latest iPhone can still fail on the phone half your users own.
- Launch, weeks 13 to 16. Store submission, staged rollout, monitoring switched on, and a month of fixes included while real usage tells you what to change first.
If your timeline is tighter than that, read how long an MVP takes: the way to go faster is fewer features, not fewer steps.
The technology we use
Flutter and React Native for cross-platform work, Swift and Kotlin when an app needs to be native, and Node, Python or Laravel behind them with PostgreSQL or MongoDB. Firebase for notifications and analytics when it fits, AWS or Google Cloud when it does not. The full list, and how we choose, is on the technologies page.
We keep the list short on purpose. A team that is excellent with five tools beats a team that is average with forty.
Adding AI to a mobile app
Most apps do not need AI. The ones that benefit usually need one of three things: search that understands what people mean, a summary where users currently read a lot, or a way to turn a photo or a voice note into structured data.
We build those as a separate service behind your API, so the app stays fast and the AI can be switched off per user while you measure whether it helped. If AI is the centre of your product rather than a feature, that is AI MVP development instead, and if you already have an app, see AI integration.
Taking over an app someone else built
We do this regularly, and it starts with an audit rather than a quote: the code, the crash reports, the store listings and the backlog. Two weeks later you get a written answer on whether to fix, refactor or rebuild, with the cost of each. We have talked clients out of rebuilds that would have cost them a year.
What it costs and how long it takes
Our mobile projects usually run 8 to 16 weeks, with the price fixed after discovery. The three things that move it most are the number of user types, whether you take payments, and how many outside systems the app has to talk to. The market ranges, including what changes them, are in our app development cost guide for India.
