This app is extremely simple. There are no ads, no glitches, and no pop ups. Pretty much nothing that annoyed me about the other 5 apps I tried. I have audio book files that I pulled off of CDs and uploaded to my google drive. They imported to this app from there easily. There are a million features that people might like which are missing from this app (pause from iPhone headphone button, select multiple files at a time, separate files from different books into their own folders, FFW/RWD) which I would've liked, but the features that it has work flawlessly. Namely, it remembers where you left off, allows control from lock screen, and doesn't have annoying bugs or ads. The worst annoyance that OTHER APPS tend to have is that they forget where I left off or skip around in between listenings. This app played exactly where I left off perfectly every time I opened the app. That reliability is my favorite thing about it. Following that, its simplicity and playback speed control make using it a very pleasant experience. As long as they keep these characteristics, this will be the only app I will ever use again for audiobooks. I very much enjoy how it is designed and functions. If they can add any of the missing features that I mentioned above while maintaining all of the positive characteristics, I'll be changing my review to five stars.
While folders are not available yet, BookPlayer now has support for playlists and remote controls as well as a brand new interface for adjustable forward and rewind. We hope you enjoy the upgrade.
