**Strengthen your internal sense of rhythm.** Time Guru is the only metronome that periodically goes silent—randomly, in patterns, or both—so you discover whether you rush, drag, or lose your place. **Random & Pattern Muting** Set any percentage of random muting to test your timekeeping. Or create sequenced muting patterns. Or combine both. You'll quickly learn where your time falls apart—and strengthen it. **Complex Meter Sequences** Build unlimited chains of shifting meters: 4/4 -> 7/8 -> 3/4 -> 11/16 -> 4/4 -> 3/8. Meters go up to 16/x, patterns have no length limit, and you can rearrange them with drag-and-drop. **Gradual Tempo Changes** Automatically speed up or slow down over time—perfect for building technique. **Practice Timer** Set the metronome to stop after a specified duration. **Also includes:** • 35 loud, clear sound sets • Drum machine-style rhythmic patterns • Voice counting in English, Chinese, French, German & Russian • Tap tempo (5–300 BPM) • iCloud backup and sync • Light and dark themes • Full VoiceOver accessibility • Rock-solid timing via custom audio engine Developed by Avi Bortnick and Adam Bellard
