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.

Enjoying new exotic songs, but have no idea what their unfamiliar harmonies are doing? With a little training, you can recognize and reproduce crazy harmonies yourself! TRAIN YOUR EAR, TRAIN YOUR VOICE Interval Ear Trainer turns ratios from JI (just intonation) and EDO (equal divisions of the octave) into focused, colorful practice sessions. Choose prime limits from 5-limit (traditional Western harmony) through 7-limit, 11-limit, 13-limit, and higher. Then, identify the intervals you hear. Targeted practice brings back troublesome intervals with nearby contrasts and familiar landmarks. Once you've trained your ear, train your voice with Hum mode, and let the app detect how close you are to singing intervals. Or, get started on recognizing chords, scales, and even scale progressions!
