FAQ
Do I need internet to use the app?
No, that's the whole point! The app stores all data locally on the device using Room/SQLite. It works 100% offline, anywhere, anytime.
Can data be transferred between devices?
Yes! On Standard and Premium packages I can add export to CSV, PDF, or Excel so you can share data easily. Local WiFi sync between devices is available as a custom add-on.
What if I need to add online sync later?
No problem. I build the app with clean MVVM architecture, making it easy to add a backend (Firebase, REST API) later without rewriting the whole app.
Will I get the source code?
Yes, always. You'll receive the full Android Studio project with all source files, resources, and assets. The code is 100% yours.
Which Android versions are supported?
The app will support Android 7.0 (API 24) and above, covering 95%+ of active Android devices.
Can you add a simple admin panel or settings screen?
Yes! A settings screen is included in all packages. A full admin panel with user roles is available in the Premium package.
