Plan your mobile app Compare native, hybrid, and cross-platformFrequently asked questions about mobile application development
Should I build a native app or a cross-platform app?
Choose native (Swift or Kotlin) when you need the best device performance and deep hardware access. Choose cross-platform (Flutter or React Native) when you want one codebase, a shorter timeline, and a smaller budget.
How much does it cost to build a mobile app for iOS and Android?
Cost depends on features, design complexity, and whether you build native or cross-platform. A cross-platform app for both stores is usually less expensive than two separate native builds, since much of the code is shared.
How long does mobile app development take from idea to launch?
A simple app can launch in 3 to 4 months, while a feature-rich app with backend integration and complex workflows can take 6 to 9 months, including testing and app store review.
Can you add a mobile app to a system we already run?
Yes. We connect new mobile apps to existing backends, databases, and APIs, so the app extends your current system instead of duplicating it.
Do you handle App Store and Google Play submission?
Yes. We prepare the required assets, complete the submission process for both stores, and handle any resubmissions needed to meet review requirements.
What support do you provide after the app is published?
We provide 24/7 support and bug fixing, monitor crash reports and performance, and release updates to keep the app compatible with new OS versions.
