App Development services by IndSoft24

Your customers live on their phones. IndSoft24 builds mobile apps that feel fast, look polished and keep users coming back — whether you are launching a startup MVP, digitising field operations or giving existing customers a better way to order, book or pay.

We develop cross-platform apps with Flutter and React Native, which let one codebase power both Android and iOS and cut development cost and time significantly. When your product needs deep hardware access or maximum performance, our engineers build fully native apps in Kotlin and Swift.

Every app is backed by a secure, scalable backend and an admin panel to manage users, content and orders. We handle Play Store and App Store submission, crash monitoring, analytics and post-launch updates, so your app keeps improving after release.

Frequently asked questions

How much does it cost to build a mobile app in India?

Cost depends on features, platforms, backend complexity and integrations. A focused MVP costs significantly less than a full-featured product, which is why we often recommend launching an MVP first. We provide a fixed-scope estimate after understanding your requirements.

Should I choose Flutter, React Native or native development?

For most business apps, Flutter or React Native offers the best balance of cost, speed and quality. We recommend native Kotlin/Swift only when your app needs deep hardware access or maximum performance.

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

Yes. We prepare store listings, handle review guidelines and publish the app under your developer accounts.

Will I own the source code?

Yes. On final payment you receive full ownership of the source code, designs and documentation.

Do you provide app maintenance after launch?

Yes. We offer maintenance plans covering OS updates, bug fixes, performance monitoring and new feature development.
