What does a Flutter and React Native app development company do?
It builds one cross-platform codebase in React Native or Flutter that ships to both the App Store and Google Play, or native iOS and Android apps when the product needs them, together with the backend, APIs, admin panel and store release the app depends on. Digital Patron does this from offices in Gurugram and Mohali, India, and quotes a fixed price per project after a discovery call.
Cross-platform, done properly
Pick the framework for the product, not for the vendor.
Most business apps need both stores and do not need platform-specific hardware features. For those, one codebase in React Native or Flutter is the sensible default: one team, one backlog, one release. When the app leans on Bluetooth, background processing, heavy animation or deep OS integration, we build native Kotlin and Swift instead, and we will tell you which on the discovery call. Our wider app development page covers native builds in more depth.
Whichever framework we pick, the scope is the same: the mobile app, the API and database behind it, the admin panel your team uses to run it, analytics, and the App Store and Google Play process. For The Hotel Media we built a web platform and a native Android app on one API with real-time sync over 16 weeks; for Nimitai a meeting-intelligence platform over 12 weeks. Neither is a Flutter or React Native app, and we say so plainly below rather than dressing them up.
We do not publish a rate card for app builds. Every project is quoted as a fixed price after discovery, in INR with GST for Indian clients and in USD for international clients. For typical Indian market ranges, read our app development cost guide.
- React Native with Expo, or Flutter, for one codebase on iOS and Android
- Native Kotlin and Swift when the product needs it, decided at discovery
- Backend, APIs and admin panel scoped alongside the app
- Installable test builds every week on real devices
- App Store and Google Play release under your own developer accounts
- You own the code, repositories, store accounts and cloud accounts

How app pricing works
- Every build is quoted as a fixed price per project after a discovery call; we do not publish a rate card
- Indian clients are invoiced in INR with GST; international clients in USD
- The backend, admin panel and store release are always inside the quote, never an add-on
- Typical Indian market ranges by app complexity are in Mobile App Development Cost in India (2026)
Store accounts and usage-based services (hosting, SMS OTP, maps, push) are billed to you by the providers at their rates.

What we build
Everything a cross-platform app needs to ship and stay live.
Mobile, backend, admin tools and release, in one accountable scope.
Flutter
Dart apps with Flutter's own rendering engine, so the UI looks and behaves the same on iOS and Android, with custom and animation-heavy interfaces where that matters.
Native iOS and Android where needed
Kotlin and Jetpack Compose, Swift and SwiftUI, either for the whole app or as native modules inside a Flutter or React Native app.
Backend, APIs & Admin Panels
Node.js APIs, databases, authentication, file storage and the web dashboard your team uses to run the app.
Real-Time, Push & Payments
Socket-based live updates, Firebase Cloud Messaging, deep links, and payments through Razorpay, Stripe or UPI.
Security, Compliance & Ownership
Role-based access, encrypted storage, consent flows and store privacy declarations, with code, store and cloud accounts in your name from day one.

How we work
From framework decision to both stores.
Six phases, an installable build every week, and no surprises in the final fortnight. Most cross-platform builds run 4 to 12 weeks depending on scope.
- Step 01
Discovery & Framework Decision
We map who uses the app, where and when, then decide React Native, Flutter or native against the product's real requirements and your team's skills, and define the smallest first release that proves value.
Signed SOW, framework decision and fixed quote - Step 02
Design System & Prototype
Wireframes, a component system and a clickable prototype you can test on a phone before development starts.
Stakeholder-tested prototype - Step 03
API Contract & Backend
We define the API that the app, admin panel and any web front end share, then build the backend alongside the mobile work.
One contract for every client - Step 04
Build Sprints
Two-week sprints with TestFlight and Play internal-track builds every week, so you use the app as it grows.
Working app every week - Step 05
QA & Store Submission
Real-device testing across OS versions and screen sizes, then store listings, privacy declarations and review handling under your developer accounts.
Live on App Store and Google Play - Step 06
Launch & Iterate
Phased rollout, crash and analytics monitoring, a 30-day stabilisation window, then a roadmap for the next release.
Stable release + next-release plan
Framework choice
Flutter, React Native or native: how we decide
All three are production-grade in 2026. The right one depends on the product and the team that will maintain it, not on which framework an agency prefers. The table is the short version of the conversation we have on the discovery call.
- Choose Flutter when the design is custom and must look identical on both platforms, or when you also want web or desktop from the same code.
- Choose React Native when your team or your existing product is in React or TypeScript, or when over-the-air updates matter for your release cadence.
- Choose native when the app depends on Bluetooth, sensors, background work, widgets or platform features that cross-platform bridges handle poorly.
- Mixed is normal: a Flutter or React Native app with one or two native modules is often the right answer.
| Factor | Flutter | React Native | Native (Kotlin / Swift) |
|---|---|---|---|
| Language | Dart | TypeScript / JavaScript | Kotlin for Android, Swift for iOS |
| How the UI is drawn | Flutter's own rendering engine draws every pixel, so screens look identical on both platforms | Renders real platform components through the New Architecture (Fabric renderer, JSI, TurboModules), so screens feel native to each OS | Platform UI toolkits directly (Jetpack Compose, SwiftUI) |
| Best for | Custom, animation-heavy or brand-led interfaces; teams comfortable with Dart | Teams that already work in React or TypeScript; products that share logic with a React web app | Heavy use of device hardware, background processing, widgets, platform-specific features |
| Tooling and updates | Flutter CLI, Firebase; store release for every change | Expo and EAS for builds and submissions; over-the-air updates for JavaScript-only changes | Android Studio and Xcode; store release for every change |
| Third-party SDKs | Good coverage; some vendor SDKs need a platform bridge | Broad coverage; most vendors ship a React Native package | Every vendor SDK, first |
| Other targets | Web and desktop from the same code | Web via React Native Web or a separate React app | Mobile only |
We work in all three, so the recommendation is not tied to what we would rather build.
Timeline
How long a cross-platform build takes
Most cross-platform builds run 4 to 12 weeks from signed SOW to store release, depending on scope: the number of screens, whether payments and user roles are involved, and how many integrations the app needs. Builds with real-time sync, several user roles or offline handling run longer; The Hotel Media build, a web platform plus a native Android app on one API, took 16 weeks.
You get an installable build every week through TestFlight and the Play internal track, so there is no reveal at the end. The most common reasons a timeline slips are third-party integrations and slow access to APIs or test environments, so we chase those in week one.
Cost
What a Flutter or React Native app costs with us
We quote a fixed price per project after discovery, not a day rate or a published package. The quote covers the app, the backend and admin panel, store submission and a 30-day stabilisation window after launch. Indian clients are invoiced in INR with GST; international clients are invoiced in USD.
A cross-platform build is usually cheaper than two native apps because one team ships one codebase, but the backend, design and QA cost about the same either way, so the saving is on the mobile layer rather than the whole project.
- Store accounts: the Apple Developer Program is US$99 a year; a Google Play developer account is a one-time US$25, both in your name.
- Running costs: hosting, SMS OTP, maps, push and other APIs are usage-based and billed by the providers.
- Maintenance after the stabilisation window is quoted separately as a monthly retainer.
For typical Indian market ranges by app complexity and the features that move the price, read Mobile App Development Cost in India (2026).
Ownership and compliance
You own the code, the store accounts and the data
- The code repository is created in your GitHub or GitLab organisation from the first commit, with our team added as contributors.
- Apple Developer and Google Play accounts are opened in your company's name; we work inside them as team members and are removed when you choose.
- Cloud, database, Firebase and third-party service accounts are yours, with billing to your card and credentials handed over at launch.
- App Tracking Transparency, Play Data Safety declarations, consent flows and India DPDP and GDPR-aware data handling are designed in from the first sprint.
- Handover includes architecture notes, environment setup and a release checklist, so another team could maintain the app without us.

Frequently Asked
Questions, answered. about Flutter & React Native App Development in India.
Clear, commercial answers. No vague agency language, no hidden pricing signals, and no empty “it depends” answers.
Pick React Native when your team or existing product already works in React or TypeScript, when you want Expo's build and over-the-air update tooling, or when most vendor SDKs you need ship React Native packages. Pick Flutter when the interface is custom and must look identical on both platforms, when your team is comfortable with Dart, or when you also want web or desktop from the same code. If the app depends on Bluetooth, sensors, background processing or widgets, native Kotlin and Swift is usually the better answer. We work in all three and make the call with you at discovery; see how we decide.
We quote a fixed price per project after a discovery call, covering the app, backend, admin panel, store submission and a 30-day stabilisation window. Indian clients are invoiced in INR with GST; international clients in USD. We do not publish a rate card. For typical Indian market ranges by app complexity, read our app development cost guide.
Most cross-platform builds take 4 to 12 weeks from signed SOW to store release, depending on screens, payments, user roles and integrations. Apps with real-time sync, several roles or offline handling take longer; our build for The Hotel Media, a web platform plus a native Android app on one API, took 16 weeks. You get an installable build every week throughout.
You do. The repository lives in your GitHub or GitLab organisation from the first commit, the Apple Developer and Google Play accounts are opened in your company's name, and cloud, database and third-party service accounts are yours with billing to your card. We work inside them as team members and hand over credentials, architecture notes and a release checklist at launch. See ownership and compliance.
Yes to both. The API, database, authentication, push notifications and the web dashboard your team uses to run the app are part of every scope. We prepare store listings, screenshots, App Privacy and Play Data Safety declarations, submit under your developer accounts and handle reviewer feedback. During development we distribute builds through TestFlight and the Play internal track.
Our published product work is The Hotel Media, a web platform plus a native Android (Kotlin) app with real-time sync, Nimitai, a meeting-intelligence platform, and the ToothCare.ai healthcare chatbot listed on our projects page. None of those is a Flutter or React Native app, so read them as proof of how we scope, build and release products, including the backend and real-time layers a cross-platform app needs. We work in React Native and Flutter and will walk you through the code of a current build on the discovery call.
