New: Learn. Can't play a challenge yet? Learn plays the notes the click doesn't, steps back as you lock in, and ends once you've played it clean. Free, nothing saved.
Most metronomes just count. RhythmForge listens back.
Play along to the click and the app hears every stroke through the microphone. You see each hit land early or late, by how many milliseconds, and after the session where your timing held and where it drifted. Rushing or dragging, you'll know which.
HOW IT WORKS
Practice: turn on listening, play, and watch the timeline. The metronome plays one subdivision, you play another: eighths over a quarter click, triplets, offbeats.
Challenges: pick one, set your tempo, play. Every beat is scored across six tiers, from Perfect (within 10 ms) to Missed. Consecutive Perfects build a combo. Your best score is kept with the tempo you set it at.
Learn: can't play a challenge yet? Learn plays the notes the click doesn't cover, steps back as you lock in, and ends once you've played enough clean bars. Then start the challenge for real. Learn is free, costs no energy and saves nothing.
60+ challenges: rudiments (singles, doubles, paradiddles, rolls, gallops), grooves, world rhythms (tresillo, son clave, rumba, cáscara, mozambique, bossa nova, samba, baião, bembé), compound and odd meters, tempo ramps and silent bars.
WHAT YOU GET
• Live feedback on every stroke, measured in milliseconds
• Rushing and dragging per session, timing spread, beat distribution
• Assist: playing a different part than the click and lose it for two bars? The click steps back and your notes play until you're back. Those bars stay out of your accuracy
• Tempo ramp and ghost measures (silent bars, the clock keeps running)
• Per-device latency calibration, with AirPods drift corrected as you play
• Works with a practice pad, snare, hand percussion, claves, djembe
• 20 to 360 BPM, every standard subdivision, accents, odd meters
• Hold the tempo to type it, tap it, or slide a ruler
• Dark design, true black for OLED

WHO IT'S FOR
Drummers and percussionists practicing on a pad, a snare or hand drums. Guitarists, bassists and producers who want tighter time. Students and teachers.

Privacy: your audio never leaves the phone. Timing detection runs on-device. Analytics are anonymous.
Requires iOS 17 or later. Microphone access is needed for timing feedback.

Ratings & Reviews
Learn a pattern first.
• Learn: under every challenge's pattern, a Learn button plays the challenge with no score. Where the click doesn't cover your notes, Assist plays them from the first bar until you're in, and a line under the progress shows whether you're rushing or dragging. Once you've played enough bars in time in a row, Learn tells you how they went and where your best stands, and Start challenge is right there. Learn is free on every challenge, costs no Energy and saves nothing.
• Sticking: the rudiments show which hand plays each note, R and L under the notation and under the timeline as you play.
• Small fixes and improvements.
