EarTube Real Ear Trainer is an ear training app that uses real audio clips via youtube to demonstrate chord changes. This app is perfect for music students :)
The app provides examples of chord changes in songs and can be used for ear training. For a more fully-featured app check out ChordProg 2 Ear Trainer.
Atm, this is just a small MVP, so if you like the concept be sure to drop a review! If you dont the app will simply fizzle out, so leave a review and show it to your fellow music students :D
