A little friendly
competition.

Six musical puzzles. Two listens each. No speed bonus and no Pro advantage.

Open this invitation on your iPhone with HearBack installed. You can also enter its code in the Compete tab, under Play → Have a duel code?

No friend free right now? Quick match finds another listener near your league, and when the queue is quiet a HearBack rival bot steps in. Bots are always marked as bots and never change your league.

Your current practice stays saved.
