Mobile app development
One codebase, two app stores, no compromises users can feel
We build Android and iOS apps in Flutter and React Native, together with the backend, the admin panel and the release pipeline, so the app is a working product rather than a front end waiting for an API.
Both build Android and iOS apps from one codebase. Flutter uses Dart and draws its own interface, which gives consistent visuals and strong performance. React Native uses JavaScript or TypeScript and native components, which suits teams that already work in React.
TechNimbus builds in both. We usually recommend React Native if your team already uses React on the web, and Flutter when the app is design-heavy or the team is starting fresh.
What is included
Everything a real app needs
The app itself
Android and iOS from one codebase, with platform-specific polish where users notice it.
The backend
APIs, authentication, push notifications and data storage, built with the app rather than after it.
Admin panel
A web dashboard for your team to manage users, content and orders.
Payments
Razorpay, Stripe and in-app purchases, implemented to each store's rules.
Analytics and crash reporting
Know what users do and what breaks, from the first release.
Store releases
Play Store and App Store submissions, review fixes and a release process your team can repeat.
Compared
Flutter versus React Native at a glance
| Flutter | React Native | |
|---|---|---|
| Language | Dart | JavaScript or TypeScript |
| UI approach | Draws its own widgets | Uses native platform components |
| Best when | Design-heavy apps, new teams, consistent look across platforms | Teams already using React, sharing code with a web app |
| Performance | Excellent for most apps | Excellent for most apps, with the newer architecture |
| Hiring pool in India | Large and growing | Large, overlaps with React web developers |
Market context
What mobile apps and developers cost in India
Dotsquares estimates that a mid-complexity mobile app built by an Indian team typically costs $15,000 to $60,000, compared with roughly $80,000 to $250,000 for an equivalent project in the US or UK.
For hiring, Jellyfish Technologies puts senior mobile developers in India (React Native, Flutter, iOS and Android) at $45 to $70 an hour, or $7,200 to $11,200 a month for a dedicated senior developer.
These are market figures rather than TechNimbus prices. We quote each app after a discovery call, with the scope written down. Sources: Dotsquares, Jellyfish Technologies.
How long does it take to build a mobile app?
A focused first version with a handful of core features is much quicker than a full product with payments, chat and an admin panel. We give you a realistic timeline after discovery, broken into milestones you can see.
Do you publish apps to the Play Store and App Store?
Yes. We prepare store listings, handle submission and review feedback, and set up a release process so future updates are routine. Apps are published under your own developer accounts.
Can you build the backend as well?
Yes. We build the APIs, database, authentication and admin panel alongside the app, typically in Node.js or Python, or connect to your existing backend.
Can you take over an app another developer built?
Yes. We review the code, dependencies and build setup first, then tell you plainly whether to continue, refactor or rebuild parts of it.
Can we hire a Flutter or React Native developer instead of a project?
Yes. If you have product direction and need engineering capacity, you can hire a dedicated or contract mobile developer.
