Rhythm Cat / Treble Cat / Bass Cat

If music theory feels intimidating, the Rhythm Cat, Treble Cat, and Bass Cat apps turn note reading into quick, arcade-style challenges kids are actually willing to repeat. Developed by Melody Cats as simple practice games, they focus on core skills: Rhythm Cat builds timing and counting, while Treble Cat and Bass Cat drill note recognition on each staff. Kids tap answers to earn stars, unlock levels, and see their speed improve over time, making the repetition that sight-reading requires much more palatable. Parents like that sessions can be just a few minutes and that the apps work well alongside any instrument lessons. The apps are low-cost, one-time purchases (not pricey subscriptions), though they’re best viewed as practice tools, not full music curricula. For even better value, pair them with real sheet music so kids can connect the game to what they’re playing.
