From the creators of DefleMask and Minimic, introducing Polybeep, a magnificent polyrhythmic sound machine designed to unlock your creativity. We even prepared a built-in tutorial to get you started. With aesthetically pleasing colors and design alongside unmatched visual feedback, you can really feel the beeping beeps and the poly rhythms. Yes, you can set up polyrhythms as easy as 3-4-5. You can record sounds directly from your microphone or load sample files. There’s some magic to make them sound great. Arrange the sounds into up to 6 looping shapes that can be configured as polygons of 3~16 vertices, then tweak their effects (delay, reverb, EQ, panning, chorus, and more), make a sequence of many melodies, and you’ll have a song in no time! You can even tap to change the tempo based on a rhythmic pulse. MIDI device input is as well supported! MIDI output coming soon! (notes, sync) macOS version is also available! Polybeep has been designed with a touch screen in mind from day one but it works perfectly fine on computers. When ready, you can save your songs and export them to wav files. We’d love to hear the songs that you come up with!

Verdict
The clearest difference is price: VelocityScaler at Free against Polybeep's $4.99. Polybeep's advantage is update cadence (fortnightly vs monthly) and iOS requirement (12.0 vs 17.6). On ads, in-app purchases and device support there is nothing between them.
