Why React Native

Write Once.
Run Natively Everywhere.

React Native bridges JavaScript with real native components — no WebView, no compromise. Your app feels exactly like a native app because it is one.

⚛️
True Native Components
React Native renders real iOS UIKit and Android Views — not HTML. Users get native scrolling, transitions, and gestures that feel exactly right.
⚡
JavaScript + Native Bridge
Business logic lives in JS while UI is rendered natively. The new JSI architecture eliminates async bottlenecks for even faster performance.
🔄
Fast Refresh
See UI changes in milliseconds without losing app state. Our devs iterate at speed — cutting development cycles by up to 35% vs native.
🌐
Massive Ecosystem
Tap into the entire npm ecosystem. Tens of thousands of battle-tested packages, plugins, and community components ready to use.
💸
Proven Cost Savings
One JavaScript team covers both platforms. Reduce hiring, QA, and maintenance costs by 35–50% vs maintaining two separate native codebases.
🏢
Battle-Tested at Scale
Meta, Microsoft, Shopify, and Coinbase use React Native in production. Proven stability, active community, and a clear long-term roadmap.

FAQ

Frequently Asked Questions

How long does a React Native app take to build? ▾
A simple MVP typically takes 6–8 weeks. A mid-complexity app with integrations runs 12–16 weeks. Enterprise-grade apps with complex backends can take 16–24 weeks. We provide a precise timeline after a free discovery call.
Should I choose React Native or Flutter for my project? ▾
Both are excellent. Choose React Native if you have a web React team, need deep JavaScript ecosystem access, or want truly native OS-look-and-feel widgets. Choose Flutter if pixel-perfect custom UI and near-identical cross-platform appearance is the priority. We'll advise you during discovery based on your team, timeline, and app requirements.
Can React Native access device hardware like camera, GPS, and biometrics? ▾
Yes. React Native gives full access to camera, GPS, accelerometer, biometrics (Face ID, fingerprint), Bluetooth, NFC, push notifications, and any native device API — either via community packages or custom native modules written in Swift/Kotlin.
What is the cost of React Native development? ▾
Basic apps start from ₹2.5–4 lakhs. Mid-tier apps range ₹6–14 lakhs. Enterprise apps with complex backends and integrations are scoped individually. Contact us for a free, no-obligation project estimate.
Do you handle App Store and Google Play submission? ▾
Absolutely. We manage the complete submission process — Apple App Store and Google Play — including code signing, metadata, screenshots, compliance reviews, and responding to any reviewer queries.
Will I own the full source code? ▾
Yes. Upon project completion and full payment, 100% of the source code, assets, and IP are transferred to you. We also provide a full handover with documentation and knowledge transfer sessions for your team.
