Looks fantastic, will give it a try. One thing I like with SmartAudioBookPlayer on Android is for the sleep timer you can have it give a light chime and then a fadeout period - if you want to extend it you just slap/shake the phone enough to have the gyro or whatever detect motion so you don't need to open your eyes and have the light wake you back up to whatever extent. I didn't see that in the app feature list but it may be there, looks like everything else I like already is. Oh, assuming it lets you listen 'offline' with a local copy :)
Which client did you download for? Been running this in conjunction with the Android app, downloading works fine and playback sync has been pretty smooth.
On my previous phone downloading worked on its own and syncing the position of streamed files worked but the position of downloaded files wouldn't sync.
However I just switched phones and now downloading doesn't work at all (if I try to add a media folder outside of the Downloads folder it will get permission errors; if I add a folder inside the Downloads folder it will allow me to add it but the app will crash whenever I actually try to download a file).
Basically it just seems to be incredibly buggy so maybe it's just a crapshoot whether it will work on your phone.
My current setup is to host the audiobooks in a Plex library and use a third party app like Prologue [1] on iOS or Chronicle [2] on Android which both work really well for offline listening and progress tracking.
I've been using this for a couple weeks now. It's clearly in its infancy, there's a lot still to do. But even with what it is so far, it's very well done.
I'm seeing other users commenting in particular that its syncing between player devices is much more robust than any other tools offer.
This looks great! I've been self-hosting something with a similarity idea to. I can update manually, pulling metadata from Audible if available. But my version is currently just a rough set of scripts that lists from a directory and builds a static RSS feed I can listen to in Podcast Addict. The (experimental) built-in ebook reader in this project looks really intriguing to allow both collections maintained together.
