# Chaipang Math vs 라임타운

The clearest difference is update cadence: 라임타운 at every 2 days against Chaipang Math's fortnightly. Chaipang Math's advantage is iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Chaipang Math sells 3 in-app purchases, starting at $24.99 per month and 라임타운 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Chaipang Math ships an update fortnightly, 라임타운 every 2 days. The most recent releases landed on October 27, 2026 and October 31, 2026 respectively.
