# Digi vs Polyrhythm

Digi and Polyrhythm are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Digi sells 1 one-off in-app purchase and Polyrhythm sells 3 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Digi ships an update every 2 months, Polyrhythm every 5 weeks. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
