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. ► 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 with Core Data • 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.
