FAQ
Q: What is included in this gig?
This gig includes a simple Expo/React Native mobile app prototype, basic screens, navigation, Expo Go testing instructions, and source code based on the package you choose.
Can the app be tested on iPhone and Android?
: Yes. The app will be made for Expo Go testing, so it can usually be tested on both iPhone and Android through the Expo Go app.
Do you publish the app to the App Store or Google Play?
No, App Store and Google Play submission are not included in this gig. This gig is for prototypes and MVP source code only.
Do I need an Apple Developer account?
No, not for Expo Go prototype testing. You only need an Apple Developer account later if you want App Store publishing, TestFlight, or production iOS builds.
Do you provide API keys or paid accounts?
No. If the app needs an API, Firebase, Supabase, OpenAI, Google Maps, or another service, the buyer must provide their own account/API key. I can add a clear place in the code where you can paste your key.
Can you build any app idea?
Not every idea fits this gig. This gig is for simple prototypes and MVPs. Advanced apps with payments, secure login, complex backend, medical, financial, legal, crypto, or high-security features must be discussed before ordering.
Can you fix problems after delivery?
es, revisions are included based on the package you choose. Revisions cover small changes and fixes within the original order scope. New features may require an extra order.
