HiByMusic 4+

This looks and sounds like a good App but no matter what I do I can't get it to play more than 1 track before it stops.

This app is great for playing hi-res music. I have used it with local hi-res flac files with track replaygain and playback to wireless and wired headphones without experiencing any issues. I’ve also used it with the hiby fc1 dac and the dac had the correct colors for each type of song, blue for under 48khz and green for higher.
The feature I like the most is the icons for CD and HR for hi-res on each track in the list. Makes it easy to find the highest res songs in a playlist or directory.
It’s also very easy to play local files and it’s one of the very few free apps I’ve found that clearly states will play hi-res and gives you all the local file playback flexibility, without any adds. The only other app that comes close to that is Foobar but hiby’s UI is much nicer and intuitive.
My Thanks to the developers of this app!

Have spent 10 minutes with this app. I have a 512GB card in my AP80 Pro X with a few thousand tracks in FLAC, some hires. The app discovers the music on the device and allows it to be selected and played but the connection drops repeatedly and, every time it drops, the artist list starts back at the top. This makes it difficult to scroll down to get to artists at the end of the alphabet. There is a scroll bar on the right hand edge of the screen to scroll faster but that just causes the app to exit immediately so it doesn’t help. The app needs to make the connection drop and reestablish invisible to the user (unless the connection can’t be reestablished within a few seconds). I’ll wait for another update before trying the app again, it’s not good enough to use with these basic flaws. I quite like the AP Pro X though (with 7Hertz Timeless AE IEMs).
