Mobile App Development Company: FAQs
How long does it take to develop a mobile app?
A first release (MVP) usually takes 10 to 16 weeks, including design, development, testing and store submission. Complex apps with many integrations take longer.
Flutter, React Native or native: which should I choose?
Flutter and React Native let one codebase run on iOS and Android, which lowers cost and speeds up delivery. Native Swift and Kotlin is best for apps that rely heavily on device hardware or need maximum performance.
Do you publish the app to the App Store and Google Play?
Yes. We prepare store listings, screenshots and privacy details, handle submission and review, and publish the app under your own developer accounts.
Will I own the app source code?
Yes. You own the source code, designs and accounts once the project is paid for.
What does it cost to build an app?
Cost depends on the number of screens, user roles, backend features and integrations. We scope an MVP first so you can launch sooner and add features based on real user feedback.
