FAQ
Common questions
What is the FielMedina app?
FielMedina is an offline travel guide to the old medinas of Tunisia, with offline maps, audio stories and places verified by locals. Dacnis designed, built and maintains it for iOS and Android.
Should I choose a native or a cross-platform app?
Native apps (Swift, Kotlin) give the best performance and deepest device access. Cross-platform apps (Flutter, React Native) ship to iOS and Android from one code base, which lowers cost and delivery time. We recommend one after reviewing your features and budget.
Can a mobile app work without internet?
Yes. We store data on the device with SQLite, Realm or Core Data and sync it when the connection returns, as FielMedina does for its maps.
