About
Practise like it's a game. Improve like it's real.
SUS4 Practice is a full music-practice game — 250 levels across multiple themed worlds, with characters, achievements, boss levels, and Game Center leaderboards — that is actually built around real musical skills. The exercises are real: scales, arpeggios, ear training, rhythm, theory. The game mechanics make you want to come back every day.
The on-device AI tutor adjusts difficulty in real time based on your performance. A daily routine is available to every user, with no paywall on the essential practice habit. Boss levels test what you have learned across an entire world before you move on. The level packs — Jazz, Latin, Metal, Blues, and Classical — each add 50 levels built around the specific vocabulary of that genre.
