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. Tap and microphone sessions run up to 30 seconds; "no analysis" sessions run up to 5 minutes. All subdivisions, including triplets, are free.
