RHYTHM CHALLENGE – Metronome

RHYTHM CHALLENGE turns your iPhone into a rhythm coach. Play guitar, drums, or any instrument—the app listens through the microphone and shows how accurately you hit the beat. ► METRONOME THAT LISTENS Set BPM (40–140), choose subdivisions (quarter, eighth, triplet, sixteenth), and hit Record. Play along; the app detects your hits and scores your timing in real time. ► NO HEADPHONES NEEDED Train through the microphone even on your phone’s speaker—no headphones required. Prefer headphones for the most precise analysis, but you’re free to just pick up your instrument and play. ► REAL-TIME FEEDBACK See “Perfect”, “Good”, “Off”, or “Miss” as you play. Optional calibration compensates for speaker delay when using headphones. ► RHYTHM CHALLENGE MODE Patterns change every bar—great for building timing under pressure. Turn it on for a tougher workout. ► DETAILED RESULTS After each run you get: success rate, average error (ms), systematic bias (early/late), missed and extra hits, and a zone breakdown. Review your waveform and onset timeline. ► PRACTICE TOOLS • Training history • Statistics across all sessions • Export audio (WAV) and logs • Repeat the same setup with one tap ► FREE TO USE Unlimited training sessions in every mode, no sign-up. Tap and microphone sessions run up to 30 seconds; "no analysis" sessions run up to 5 minutes. All subdivisions, including triplets, are free. ► PREMIUM (OPTIONAL) Unlock full 5-minute sessions in tap and microphone modes, plus unlimited detailed analysis (free includes 3 in-depth breakdowns).
