Treyner App Smart Guitar Trainer0
Here is a smart guitar trainer that gamifies learning to help you learn new songs in no time. The Treyner reacts to you as you play and provides you feedback. It connects to your iPhone or Android device via Bluetooth and listens to you to provide guidance in real-time. It can identify deviations in a flash.
The Treyner is pretty easy to use. Simply follow the string and fret combinations shown on it to start playing. The companion app lets you configure sessions, change LED color scheme, record sessions, and play against friends. You can find this project on Kickstarter.[where to get it]
