# Metronome vs 악보ON

The clearest difference is ads: Metronome at none against 악보ON's shown. 악보ON's advantage is update cadence (weekly vs every 3 months) and iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Metronome sells 3 one-off in-app purchases and 악보ON sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Metronome ships an update every 3 months, 악보ON weekly. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
