Android & iOS app development in Delhi & across India

Mobile apps that people keep using, built on a backend that holds up.

A good app is more than attractive screens. It needs dependable login, fast data loading on weak networks, notifications that arrive, payments that reconcile, and a backend that does not buckle when usage grows. I build the app and the API behind it together, so the two are designed for each other from day one.

I use React Native for most projects, which ships one codebase to both Android and iOS and keeps long-term maintenance affordable. I have delivered production apps including a location-automated health tracking app for DIPAS DRDO and a B2B business calculator platform, taken from concept through to store release.

One codebase, two stores

React Native apps that feel native on Android and iOS, with a single codebase that is cheaper to extend.

API and backend included

Node.js APIs, authentication, databases, and admin dashboards built alongside the app, not as an afterthought.

Payments & notifications

Razorpay or Stripe payments, push notifications, maps, and camera or file uploads integrated and tested.

Store-ready releases

Play Store and App Store builds, listing assets, review requirements, and update pipelines handled for you.

FAQ

Frequently asked questions: Mobile App Development

Should I build my app in React Native or native Android and iOS?

For most business apps React Native is the better choice: one codebase serves both platforms, development is faster, and maintenance is cheaper. Fully native development makes sense for apps that depend on heavy graphics or deep device-level features, and I will tell you honestly if that applies.

How much does mobile app development cost in India?

It depends on the number of screens, backend complexity, integrations such as payments or maps, and whether an admin dashboard is needed. You receive a fixed, milestone-based quote after scoping, and a lean first version can be planned to control cost.

How long does it take to develop and launch an app?

A focused first version typically takes six to ten weeks including backend and store submission. Complex products are delivered in phases so you can launch sooner and grow the app with real user feedback.

Do you publish the app on Google Play and the App Store?

Yes. I prepare release builds, handle signing, write store-compliant listings, and manage the review process on both stores, including resubmissions if a reviewer requests changes.

Will I own the source code?

Yes. You receive the full source code for the app, backend, and admin panel, along with documentation and repository access.

Do you provide support after the app launches?

Yes. Post-launch support covers bug fixes, OS compatibility updates, performance monitoring, and new features, either as needed or on a monthly maintenance plan.
