PolyCyclo vs Epicycle

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/

Epicycle is a MIDI sequencer for iPhone and iPad. Every rhythm is a Euclidean ring, and each track's parameters generate its pattern. Layer rings of different lengths for polymeter, and hear them on the built-in sound engine with no external gear. EUCLIDEAN RINGS Each track is a ring, and you can run up to eight at once. A track's pattern follows from its parameters, so you see the rhythm as a shape. POLYMETER Give tracks different lengths and they play together. Loop-lock protects one track's pattern while you change the others. SCENES Save pattern states as scenes and launch them with quantize. FREE TO PLAY Epicycle is free to download. The full sound engine and every creative feature are free, up to eight tracks, with no time limit. MIDI OUT, CLOCK AND EXPORT A one-time lifetime unlock adds live MIDI out, MIDI clock in and out, and .mid export, so you can drive and sync external hardware and apps. Requires iOS 18 or later. VoiceOver is supported.
