Finally, an app for my audiobooks

Over the years I have downloaded Overdrive books as well as audiobooks on cd’s with the intent of listening to them eventually on an iPod. With the advent of Bluetooth earbuds, it has become much more convenient to listen wirelessly while working in the yard or working out. I wanted to use my old iPhone 5S like an iPod, but Apple only offered Apple Music as a player when I copied my books from iTunes on my MacBook to my old phone. But that app didn’t allow bookmarks, faster listening speeds or certainty that your place in the book would be the same if you stopped listening, then started again the next day. So often, Apple Music would start up at the beginning of your current file, which file could be 70 minutes long. It’d be a pain in the neck to have to keep fast forwarding the audio to find the place where you had left off. I started to screen shot the player so that I could more easily regain my position if Apple Music had decided to go back to the 0:00 position. Thankfully, with BookPlayer, I have an app that solves all of the problems with Audiobooks that Apple Music ignored.

Two Issues Keeping App from 5 Stars

There are two issues that are keeping me from rating this App 5 Stars: 1: Chapter starts are clipped when using the chapter picker and 2: when importing an audiobook (I use OneDrive), no cloud download progress is shown. The file just suddenly appears after it has downloaded. It needs to show download progress!! The first issue was almost a deal killer for me (and why I’ve given it 2 stars). Why does the App not play the audio starting at the chapter marker when a chapter is selected? It seems to either suppress or skip the audio starting at the chapter marker to somewhere between 1 to 2 seconds later. This means if you’ve got chapter markers closer than 1 second before the start of audio, the start of the chapter audio is probably clipped if you’ve the chapter picker to start a chapter. No other audiobook player I’ve tried does this. They all play audio starting at the chapter marker when using their chapter pickers. The second issue is just plain craziness. I can’t remember the the last time I used an App that didn’t show download or transfer progress. I think maybe 40 years ago ( at the start of the PC revolution)? When I started using the app, I tapped on the the audiobook multiple times in the file picker, because the app gave me no feedback it was downloading the file. With a large audiobook and slow internet, it can take 5 to 10 minutes for the audiobook to show up. Please add download progress functionality.

Stop begging for reviews ,

Simple, bugless, no annoying ads or pop ups.

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.

Developer Response ,

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.
