This app is one of the newest members of the TntMPD ecosystem by a third party developer. It will provide a copy of your TntMPD information on your iOS mobile device. This way you always have your information with you. You can make changes to the data, and it will sync back to your main TntMPD database.
It's already in the app store, but the desktop connector is still under development. So, please be patient while the final touches are being finalized.
Here's a link to the iTunes app store for more info:
