Tomplay Interactive Sheet Music with Backing Tracks

I just discovered this app that combines sheet music with play-along tracks in useful ways: https://tomplay.com/

It started out with a focus on classical music, then branched out a little jazz and pop. I love being able to play with a piano or harpsichord accompanist on a Telemann flute sonata, with the ability to adjust the speed for practice, and to record myself in a pretty decent way along with the accompanying part.

It seems like it'd also be a good way to practice sight reading.

N.B. I don't have any affiliation with the app, just thought it was cool.
