RHYTHM CHALLENGE – Metronome

Play any instrument—the app hears you and scores your timing in real time. Try Rhythm Challenge mode!

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.

► PREMIUM (OPTIONAL) Unlock full 5-minute sessions in tap and microphone modes, plus unlimited detailed analysis (free includes 3 in-depth breakdowns).

Built for musicians who want to improve timing and feel. No wires, no tapping on the screen—just play and get honest feedback.
