Most metronomes just count. RhythmForge listens back. Play along to the beat and the app hears you in real time. Every hit is measured, every drift is shown, every session tells you exactly where your timing is strong and where it's not. Your phone becomes a practice coach. HOW IT WORKS Pick a challenge. Set your tempo. Play. RhythmForge scores every beat across six accuracy tiers — Perfect, Great, Good, Okay, Weak, Missed. Build combos with consecutive Perfects for bonus points. Beat your personal best. See exactly where you rushed or dragged. 63 built-in challenges spanning rudiments (singles, doubles, paradiddles, rolls, gallops), grooves, world rhythms (tresillo, son clave, rumba, cáscara, mozambique, bossa nova, samba, baião, bembé), compound and odd meters, and odd subdivisions. From first-week beginner to serious drummer.
