Both are free to download. ioio sells 6 one-off in-app purchases and Cozy Mahjong sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

ioio holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Cozy Mahjong has 304 ratings behind it against 26, so its average is the more settled of the two. Written reviews complicate that: 83% of ioio's written reviews are positive against 86% of Cozy Mahjong's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 4 days. The most recent releases landed on November 2, 2026 and October 30, 2026 respectively.
