Flutter & React Native Apps

Flutter & React Native App Development Services in India

We build cross-platform iOS and Android apps that feel native — using Flutter when polish and 60fps animations matter, or React Native when speed-to-market and shared code with the web matters more. From MVP launches to enterprise apps with 100k+ users, we handle the full lifecycle: design, native module integration, App Store and Play Store submission, push notifications, analytics, and ongoing version updates.

Why teams choose us for Flutter & React Native Apps

Most cross-platform mobile work we audit was built on Flutter or React Native by web developers who never published to the App Store. The result: apps that work fine in development and break on real devices because they ignored iOS keyboard behavior, Android back-button handling, deep linking, push notification permissions, or App Tracking Transparency. We've shipped 5+ apps to both stores and we've been through the rejection cycles — our apps clear App Store review on the first submission ~80% of the time.

When Flutter & React Native Apps is the right choice

Cross-platform (Flutter or React Native) is the right choice when you need both iOS and Android, your team isn't native iOS+Android specialists, and your UX is mostly standard mobile patterns (lists, forms, video, maps, navigation). It's NOT the right fit when you need deep platform-specific integration (CarPlay, Apple Watch, advanced ARKit, Android system-level APIs), or when your app is performance-critical at the level of high-end games or AR/VR. For those: native Swift/Kotlin wins.

Our Flutter & React Native Apps Process

1
Platform & Stack Choice

Flutter or React Native? We pick based on team skills, design polish requirements, web app overlap, and your existing codebase. We'll explain the tradeoff in the first call so you understand the choice.

2
Backend & API Contract

Mobile apps need a backend. We design the API contract first (REST or GraphQL), build a sandbox, and let mobile + backend develop in parallel from week one.

3
Mobile App Build

Flutter (Dart with Riverpod state management) or React Native (TypeScript with Zustand or Redux Toolkit). Native modules where needed for camera, biometric auth, payments, push notifications. Offline support via SQLite or AsyncStorage.

4
Native Polish & Permissions

iOS keyboard handling, Android back button, deep links, App Tracking Transparency, push notification flows, biometric auth, in-app purchase setup, and the dozens of small details that separate shipped apps from prototypes.

5
Submission & Launch

App Store Connect setup, Google Play Console setup, screenshot generation for both stores, privacy policy, content rating, and submission. We handle the review process and respond to App Store reviewer questions.

Frequently asked questions

How much does a mobile app cost in India?

MVP apps (5-10 screens, basic features): ₹80k-₹150k. Production apps (25-50 screens, real-time, payments): ₹150k-₹400k. Enterprise / multi-module apps: ₹400k+. Final cost depends on screen count, native module needs, and whether the backend is already built or needs to be built alongside.

Flutter or React Native — which should I choose?

Flutter wins for: visual polish, 60fps animations, identical iOS/Android look, teams comfortable with Dart. React Native wins for: faster ramp-up if your team knows React, code sharing with a web app, larger npm ecosystem. We use both — pick based on team and design needs, not framework hype.

How long does an app take to build?

MVP apps: 8-12 weeks. Production apps with backend: 12-20 weeks. Enterprise apps: 20-40 weeks. Add 2-3 weeks for App Store and Play Store review on top of dev time. We work in 2-week sprints with TestFlight / Internal Testing builds every Monday.

Will you submit the app to App Store and Play Store?

Yes. App Store submission is included in every project — App Store Connect setup, screenshots in all required device sizes, privacy policy, content rating, and the review submission. We handle App Store reviewer questions and resubmissions if anything is rejected. Play Store is straightforward and similar.

Do you offer post-launch maintenance?

Yes. Mobile apps need ongoing care — iOS and Android version updates each year, framework upgrades, dependency security patches, store policy changes. Our retainers run ₹20k-₹100k/month depending on app complexity and feature roadmap. Most clients stay on retainer for 2+ years.
