FAQ

Mobile App Development FAQs

Quick answers about our services, hiring models, timelines and support. Can't find what you're looking for?

Ask our experts

Should I build a cross-platform or native app?

Cross-platform (Flutter or React Native) suits most business apps and saves time and budget with one codebase. Native (Swift/Kotlin) is better for graphics-heavy apps or apps that depend on advanced device features.

How long does it take to build a mobile app?

An MVP typically takes 8–12 weeks. Feature-rich apps with complex back-ends take 3–6 months, released in milestones.

Do you publish the app to the App Store and Google Play?

Yes. We prepare the store listings, handle builds and signing, follow review guidelines and manage the submission until your app is live.

Who owns the app source code?

You do. On final payment, all source code, designs and store accounts are handed over to you.
