iOS + Android · One codebase
React Native app development
CodeBlimp builds iOS and Android apps from a single React Native (Expo) codebase and ships them to both stores — a mobile MVP is a fixed ₹89,999 in India or $6,500 internationally and typically takes 8–12 weeks. You get native-feeling apps, over-the-air updates for fixes, and the full repository when we hand over.
What's included
- Scoping call and a written feature list with a fixed price and delivery date
- UI design for the core screens, reviewed with you before any code
- React Native + Expo build for iOS and Android from one codebase
- Authentication (email, phone OTP, Google or Apple sign-in)
- Backend and database on Supabase, Postgres or Firebase — whichever fits
- Push notifications, deep links and offline-tolerant data handling where needed
- Payments via Razorpay (India) or Stripe (international) when the app sells something
- Weekly test builds on your own phone through Expo or TestFlight
- App Store and Google Play submission, including listing assets and review fixes
- Over-the-air update channel so small fixes ship without a store review
How a project runs
One person is accountable from the first call to handover. You see the real product on a staging link every week.
01Day 0 — Scoping
A 30-minute call to cut the feature list to what the first version needs. You get a written scope, a fixed quote and a delivery date.
02Weeks 1–2 — Design and foundation
Core screens designed and approved; project, auth and backend set up. First test build on your phone by the end of week 2.
03Weeks 3–8 — Build
Features ship in weekly test builds. You use the real app every week, not a prototype.
04Weeks 9–12 — Stabilise and submit
Device testing, performance pass, store listings, submission and any review fixes for both stores.
05After launch
A 90-day bug-fix warranty is included. Care retainers cover OS updates, store compliance and new features after that.
What it costs
Two price zones, no currency conversion: India pricing is capped at ₹1,00,000; international pricing is market-rate in USD. Every price is fixed once the written scope is approved.
| Tier | Scope | Timeline | India | International |
|---|---|---|---|---|
| React Native Mobile MVP | One app, iOS + Android, auth, backend, core feature set, store submission | 8–12 weeks | ₹89,999 | $6,500 |
| Full Product Build | Mobile app + web app or admin dashboard + shared backend | 12–20 weeks | ₹99,999 | $12,000 |
What moves the price
- Number of screens and user roles (a two-sided app costs more than a single-role app)
- Real-time features — chat, live tracking, presence
- Third-party integrations: maps, payments, SMS, calendars
- Whether an admin dashboard or web app is needed alongside the mobile app
A real example

Samadhaan
Wallet and payments app with Razorpay — one of four React Native apps in the portfolio.
Built on React Native with Expo, a MongoDB backend and Razorpay for payments. Screenshots are from the delivered build; the other three apps (education, agriculture and certificate management) are in the app gallery.
See the workWho this is not for
Saying this up front saves us both a call.
- You need a game, AR, or heavy on-device video processing — those belong in native Swift and Kotlin, and we'll say so on the call.
- You want to launch in four weeks. A store-ready app with auth and a backend takes 8–12 weeks done properly.
- You only need an app because a competitor has one. Often a mobile-first web app does the job at a third of the cost — we'll tell you if that's the case.
Questions founders ask
How much does a React Native app cost?
A mobile MVP is a fixed ₹89,999 in India or $6,500 internationally, covering iOS and Android, authentication, a backend and store submission. A full product with a web dashboard is ₹99,999 / $12,000. The price is fixed once the scope is written.
How long does it take to build a React Native app?
Typically 8–12 weeks from scoping to store submission. The first test build reaches your phone within two weeks, and you get a new build every week after that.
Do you handle App Store and Google Play submission?
Yes — listings, screenshots, privacy declarations, submission and review fixes for both stores are included. You keep the developer accounts in your own name.
Will the app feel native?
Yes. React Native renders real native components, and Expo gives us native modules for camera, notifications and payments. Animations and lists are built to stay smooth on mid-range Android phones, not just flagship iPhones.
Can you take over an existing app?
Often, yes. If it's React Native or Expo we can usually continue it; if it's another stack we scope a rebuild honestly rather than patching. Share the repository and we'll tell you which within a day.
Start with a scope, not a commitment
Thirty minutes on a call, or a few lines in the form. Either way you get a written plan, a fixed quote and a realistic date.
