Start with an official source
Find the developer’s official store listing and read its current requirements and support information. Avoid APK mirrors that you cannot verify.
Complete setup
Open the app while connected and finish any required resource downloads. Record whether an account or sign-in is needed.
Try without internet
Test the intended mode with connectivity disabled. Check launch, controls and save behaviour rather than only whether the home screen appears.
Review settings
Look for sound, accessibility and notification controls. Keep enough free storage and review any permission request in context.
