FAQ

Frequently Asked Questions

How long does it take to build a mobile app?
A simple app with 5–10 screens typically takes 6–10 weeks. Complex apps with custom backends, payment integration and multiple user roles may take 3–5 months. We provide a specific timeline in the proposal after understanding your requirements.
Should I choose React Native, Flutter or native development?
For most business apps, React Native or Flutter is ideal — one codebase for Android and iOS saves cost and time. Native development (Kotlin/Swift) is recommended for apps requiring heavy device hardware access or maximum performance. We will advise which is best for your project.
Do you build the backend / API as well?
Yes — we build the complete backend API, database, admin panel and any third-party integrations your app requires. Everything is included in the proposal.
How much does it cost to build an app?
A basic app starts from ₹50,000. Most business apps with custom backend fall in the ₹1,00,000–₹3,00,000 range. Complex platforms with multiple user types can go higher. We give you a detailed, itemised quote after our discovery call.
Will you submit the app to Google Play and the App Store?
Yes — we handle the complete submission process including store listing, screenshots, description and compliance review for both Google Play and the Apple App Store.
What support do you provide after the app is live?
We provide 90 days of free bug-fix support after launch. We also offer affordable monthly maintenance plans for OS updates, feature additions and server management.
