Questions We Hear Every Week

A focused MVP usually starts in the low five figures, and because one codebase covers both platforms, it often costs less than two native apps. You get a clear, fixed-price quote after a free scoping call.
A working MVP typically ships in 8 to 12 weeks. Larger apps take longer. We share a realistic timeline with milestones in your quote so you always know what comes next.
For most apps, yes. Flutter compiles to native code and delivers smooth, near-native performance. We reach out to native APIs through platform channels wherever an app needs them.
Yes. We manage the full release on both stores: listings, assets, review guidelines, submission and post-launch fixes.
Yes. Every build ships with a support window, and we offer maintenance plans covering monitoring, OS updates, crash fixes and new features.
Absolutely. You own 100% of the source code, design files and intellectual property. We can also sign an NDA before any discovery conversation.
