My favourite audiobook player for the iPhone is Bound.
- Adjustable playback speed
- Sleep timer
- Bookmarking
- Easy to load audiobooks
- Easy to use
These are my criteria for a good Audiobook player.
You will have to pay to use all of the features, I have had lots of value from this app. This product is cheaper than buying the author a beer, and I at least owe them that 😉
Playback Speed
This has been an awesome productivity hack for me, turning an 8 hour book into 4 hours.
You will need to train your ear and mind to listen at speed, so work your way up over time, x1.2, x1.5, x1.8, x2 or more if you like.
Sleep Timer
This feature allows me to have the book stop after 5 or 10 minutes. I do this if I’m having trouble sleeping.
I know I will be asleep before 10 mins while listening.  So I setup it up and drift off. The next time I open the book, I just go back 10 mins and carry on.
Cloud Download
This was a new feature for me. But made loading books on to the iPhone a game changer.
I use Google Drive. I sync the book from my PC to gDrive, I have connected Bound to my gDrive, and I can just download the book to the phone.
No messing around with iTunes and cables, and all sorts of other unknowns.
This feature works brilliantly! And not just Google Drive also iCloud, Dropbox, OneDrive, Web Uploader.
Highly recommended. This post is basically to make it easy for me to share this app with friends who have an iPhone and want to listen to audiobooks.
