DABPlayer

Distributed AudioBook Player Sync Across Devices (optional), Take Notes, all without always needing internet access.

Human Written:

This entire app is just a way for me to solve the issue of listening to audiobooks (in mp3 format, either pulled form YouTube or pirated) without having to stream an MP3 from a home server (or even have a homeserver/something publically facing). As such, this better version of audible was born. It solved the biggest issue I faced when listening to audiobooks, not being able to 1) sync accross devices efficiently, 2) not being able to take notes when listening to a book (espetually saying notes witch the build in WhisperAI model can do). I had AI write most of the app and I basically guided the featurs/did testing of app functionality. Im sure its horrible, from a security, preformance, and bug standpoint, but its not very critical and it serves the usecase pretty well.
