Use PolyCyclo as a visual metronome. Set any whole-number tempo from 40 to 240 BPM, find a tempo with Tap, and turn on an independent reference pulse. Watch rhythm take shape as moving points, glowing traces, and polygons. Swipe between rhythms and sound sets, edit the pattern, save favorites with the star, and share a loop as MP4. Without an account or purchase, BPM, Tap Tempo, and the reference pulse are unlimited. Playback, the existing editing controls, star saves, and short watermarked MP4 export (15 seconds at 720p) are also included. Choose from the included selection of rhythms and sound sets. PolyCyclo Studio is an optional, one-time, non-consumable purchase. It unlocks all 312 rhythm presets, all 16 sound sets, watermark-free MP4 export up to 60 seconds at 1080p, and background playback. Restore the purchase any time from Settings. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
