Offline storage and cache

how I can make my app work when there is no internet using the phone cache memory. Also how to save the photos taken with my app in the phone gallery?


Not possible I’m afraid. You need internet connection.
For photos being saved to device you will need a custom component developed for that need.

Not even when app is available in Play Store? Any way to use the phone Cache?

In Adalo not possible, regardless of where the app is.
