A lot of Android music players I've used have been laggy and / or constantly nagging you to like them on Facebook, so I tried to a music player that does its job efficiently and doesn't get in your way.
As much as possible, it tries to show off the album art, both in the main player screen and in the notifications. A central goal in the design is avoiding unnecessary features and allowing the user to control their own experience, so it does not attempt to provide album art -- it only used art embedded in the mp3 files. (I can't stand apps that force the the use of incorrect cover art!)
- Notifications with controls
- A simple, clean interface
- No monetization or nagging of any kind
- Improved UI responsiveness.
- Opening via some external launchers (e.g. lock screens) could prevent Mach from allowing the CPU to sleep properly, resulting in poor battery life. This has been resolved.
- There were issues with the info area height on certain screen densities. These should now be resolved.
