Rubbrband: Practice Companion

Rubbrband is an app that tells you gives you feedback on music practice sessions. It has a smart Metronome, and a Flow mode for tracking rubato and rhythm changes.

The app is all about giving feedback to musicians in real-time to help you become better, regardless of your skill level.

When initially learning a piece of music, set your Metronome to your desired tempo and start playing! You'll be able to change time signature to match the signature of the piece you're practicing. Once you're finished, press stop, and Rubbrband will tell you when you were offbeat.

For jam sessions, use Flow! Flow will tell you when you're slowing down or speeding up to help guide your expression. It is important for musicians to play freely and vary tempo with time, so use Flow to visualize your changes in tempo and volume.
