Homer Player is an audiobook player for the elderly. Its simple user interface makes it easy to operate for seniors and people with poor vision (or both). It features simplicity so far you can even use it in "single application mode" (kiosk), to make the Android device a dedicated Audio Book Reader the user cannot "accidentally close and get lost on".

Perfect for building a dedicated audiobook player for your grandparents.

Anti-Features:

• Tracking: The application tracks and reports your activity to somewhere – usually either without your consent, or by default (i.e. you’d have to actively disable it). It’s commonly used for when developers obtain crash logs without the user’s consent, or when an app is useless without some kind of authentication.
