# Piano ∞ vs KORG Module

The clearest difference is update cadence: KORG Module at monthly against Piano ∞'s every 9 months. Piano ∞'s advantage is review sentiment (79% vs 52%) and iOS requirement (13.0 vs 15.6). On price, rating, ratings volume and ads there is nothing between them.

Both are free to download. Piano ∞ sells 4 in-app purchases, starting at $2.99 per 7 days and KORG Module sells 21 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

KORG Module holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 567 and 783 respectively. Written reviews complicate that: 79% of Piano ∞'s written reviews are positive against 52% of KORG Module's, so the app with the better star average is not the one people write more warmly about.

Piano ∞ ships an update every 9 months, KORG Module monthly. Both last shipped on October 1, 2026.
