Pro Reading speed changer
Option to shorten dead space between words. (Allows for faster playback without it sounding like chipmunks.)
Pro Volume boost + equalizer
Pro Very good at saving your position
Especially if you pay for Pro which gives you cloud sync for your position - so it's easy to restore and pick up listening even if you switch phones. Even if you don't pay, your position is stored in a file inside the book folder which you can easily copy.
Pro Auto rewind after a long pause
Goes back up to 30 seconds depending on how long the last pause was.
Pro Auto-theme app from cover art
Pro Completely customizable
So many customization features: playback position format, equalizer, playback speed, headset button actions, sleep length, skip lenghts, and more.
Pro Auto-find cover art for local books
If your book doesn't have cover art, the app can search for it for you.
Pro Reset the sleep timer with the accelerometer
Just leave the sleep timer set to 20 minutes and leave it on all the time. If you are walking or driving, it stays playing, but if you are listening in bed, it turns off on its own. If you are still listening, just give your phone a shake when you hear it start to fade and it will keep going for 20 more minutes.
Pro No official store
The author only profits from a better listening experience, not from user lockin due to no other place to get books.
Pro Supports notetaking
Written notes with a timestamp in the file, organized according to book (i.e., folder).
Pro Reads your own audio files
Copy your audio files into a folder, and this will assemble them into books based on the folder they're in.
Cons
Con Not all readers are high quality
All the readers are volunteers - people who clearly love the books, but unfortunately some recordings are very low-quality, jump around in volume, or are difficult to understand.
Some books offer different readers, but often a book has only been read by a single volunteer. For books with multiple options, you may have to jump between them to finally find who works for you.
