Frequently asked questions
Should I build a native or cross-platform app?
For most products, cross-platform (Flutter or React Native) is the fastest and most cost-effective route. Native makes sense for heavy device integrations, advanced graphics or platform-specific UX. We'll recommend the right option for your app.
How long does it take to build a mobile app?
A focused MVP typically takes 10 to 16 weeks, including design, development, testing and store submission.
Will you publish the app to the App Store and Google Play?
Yes. We handle builds, store listings and review guidelines, and publish under your own developer accounts so you keep full ownership.
Can you take over an existing app?
Yes. We start with a code and architecture audit, fix critical issues, then continue development with a clear roadmap.
