05 faq
questions, answered.
Do you build native apps in Swift or Kotlin?
No — and that’s intentional. I build with React Native / Expo: one codebase for iOS and Android, faster and cheaper to build and maintain. For most business apps users won’t notice any difference.
PWA or a store app — what should I choose?
A PWA is cheaper and faster, needs no store review and is great for catalogs, bookings and internal tools. A store app is better when you need deep device features, the store presence, or reliable push notifications on iOS.
How long does an MVP take?
Usually 4–8 weeks depending on the number of screens and integrations. We agree on the scope and the timeline before development starts.
Do you publish the app to App Store and Google Play?
Yes. I prepare the builds, store listings and handle the review process. Developer accounts are registered in your name, so the app belongs to you.
Who owns the app and the source code?
You. After the final payment you get the repository, backend access and the store accounts stay yours.
What about support after release?
Phones get OS updates every year, so apps need care. Post-release bugs get fixed, and ongoing updates and features are available monthly or per task.
