Frequently Asked Questions

How much does it cost to build a mobile app?+

Every app is different. A simple app costs less than a complex product with custom design, backend, and real-time features. Contact us for a custom quote.

How long does it take to build a mobile app?+

A simple app can take 2 to 3 months. Standard apps with backend, accounts, and push notifications often take 3 to 5 months. Complex apps can take 6 to 9 months or more.

Do I need both an iOS and Android app?+

Not always. If your audience is mostly iPhone users, start with iOS. If Android dominates your market, start with Android. Cross-platform can launch both faster with one codebase.

What is the difference between native and cross-platform?+

Native apps are built specifically for iOS (Swift) or Android (Kotlin) for maximum performance and platform features. Cross-platform apps share code across both (React Native/Flutter) and reduce build time and cost.

Do you submit the app to the stores for me?+

Yes. We handle App Store and Google Play submission, listing metadata, screenshots guidance, and compliance checks.

What happens after the app launches?+

We offer ongoing maintenance packages for OS updates, bug fixes, monitoring, performance improvements, and new feature development.

Can you build an app for my existing website?+

Yes. We can build companion apps that integrate with your existing backend or build a new backend if needed.
