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 FREE • The full metronome, tempo ramp and ghost measures included • Every click sound • Unlimited practice with live feedback and every analysis screen, nothing blurred • Learn, on every challenge • Every challenge playable, nothing locked: 6 minutes of challenge time a day, refilling as the day goes, four times faster while you practice. Out of time, any challenge still gives you a free 25-second run • Your last 7 sessions RHYTHMFORGE PRO Try it free for 7 days: • Unlimited challenge time, no meter • Pattern builder: tap in your own rhythms, loop them, score them • Triplet and sixteenth targets over any click, plus per-beat patterns • Full session history 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. It isn't a drum-kit transcriber: it doesn't tell toms from cymbals. It grades your time, not your kit. 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.

Mr. Drum is a rhythm trainer for players who want to know how their timing actually feels. Play along to studio-quality drum patterns, and Mr. Drum measures where each of your hits lands against the beat - ahead of it (Push), behind it (Layback), or right on it (Center). PRACTICE TO REAL PATTERNS - 4-beat, 8-beat, 16-beat, swing and Latin styles, each with multiple variations - Tempo from a slow practice crawl up to full speed, with tap tempo - A count-in that follows the actual time signature of the pattern (3/4, 6/8, 12/8 and more) - Per-instrument mixer so you can pull the kick up or take the ride down - Haptic metronome and a visual flasher for practicing quietly SEE YOUR TIMING, NOT JUST HEAR IT - Play along with the microphone, or tap along on screen - both are analyzed the same way - Every session gives you an average offset in milliseconds, how consistent you were, and which beats you rush or drag the most - Tempo drift is separated from feel, so "playing behind the beat" is never confused with "slowing down" - Your Groove Profile builds up over time from your practice history TIME FEEL (PRO) Shift snare, ride, toms and percussion ahead of or behind the beat independently, and hear how a groove changes when the parts do not sit in the same place. YOUR AUDIO STAYS YOURS Mr. Drum listens through the microphone, but audio is never recorded or saved. Only the timing of each hit is kept, and it never leaves your device. There is no account, no sign-in, and no server.

Verdict
The clearest difference is ads: RhythmForge at none against Mr. Drum's shown. Mr. Drum's advantage is update cadence (every 2 days vs fortnightly) and iOS requirement (13.0 vs 17.0). On price, in-app purchases, monetization model and device support there is nothing between them.
