# Polyglo vs 丸単

The clearest difference is ads: 丸単 at none against Polyglo's shown. Polyglo's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, update cadence and in-app purchases there is nothing between them.

Both are free to download. Polyglo sells 5 one-off in-app purchases and 丸単 sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 4 days. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
