App Development FAQs
Should I build a native or cross-platform app?
Most products are well served by React Native or Flutter, which share one codebase across iOS and Android. We recommend fully native Swift or Kotlin for apps that depend heavily on device hardware or complex animation.
How long does it take to build an MVP app?
A focused MVP usually takes 8–12 weeks, including design, development, testing and store submission.
Do you build the backend as well?
Yes. We build APIs, authentication, databases and admin panels, commonly with Node.js, Supabase or Firebase.
Do you publish the app to the App Store and Google Play?
Yes. We prepare store listings, handle review submission and set up release pipelines for future updates.
Can you take over an existing app?
Yes. We start with a code and architecture audit, then stabilise, update and extend the app.
