This app works great for books with separate files for chapters but fails hard for books where the entire book is one file. It seems like once you pause or bookmark a book it stops downloading or something. I had a 16 hour book cut off at 6 hours yesterday and now I can't even get it to refresh back to the correct duration. This is the second time this has happened. It's extremely frustrating.

Hmm, it should keep downloading even if you pause or bookmark. I will look in to this, thanks for letting me know. If it happens again it would be great if you could send me a log file directly after it happens. You can do that from Settings->Support->Send log

Great effort and its close to being good, but this is kind of the only game in town outside plex, so thank you to the developer for your effort. Server was kind of a pain to install, got tomcat failures until I gave up and used the docker version. Not the end of the world. However, the M4B file support is not there at all. First, the server was trying to transcode it to mp3 and failing miserably, making invalid files that wouldn't open. OK, so I disabled the transcoding, redownloaded the file, still doesn't play with the android app. However, there is nothing wrong with the file as I can take the downloaded book and play it with any other audiobook app. So this is purely a player problem in the android app. So now what, do I spend a ton of time converting from a lossless format to mp3 so this app works? Do I use this app soley as a download management app and play books with another app? Edit: I did go through the work and converted everything to chapterized MP3 and its been flawless with that so far. App has issues with M4B files and some large single MP3 files. If you split them, fix the metadata, seems like it works just fine.

Yea the m4b support is very hit and miss, it seem like more miss then hit lately unfortunately As for Air, no not at the moment. That said, adding features to Air will be much more possible then the old server so I'm hoping to better support it in the future. I'm also looking at natively support it in the app so that transcoding won't be necessary

The server software works great, however the android client not so much. It especially seems to have issues with large files, it often won't remember positions within a book, it fails to download properly, I can't even scrobble to a location in the book because it'll just not do anything. It's essentially unusable unless your book library is split into much smaller mp3's. Could you at least add a download progress so we know if anything is happening?

Sorry to hear that. I will try and replicate the problem with large files and if I can I will get a fix in the next version. When a file is downloaded you get a notification showing the progress, the percent that has been downloaded will also show next to the filename. Contact me at for help if this is not showing up for you.

What's new
