# Chaipang Math vs Adaptus

The clearest difference is update cadence: Adaptus at every 5 days against Chaipang Math's fortnightly. Chaipang Math's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.4). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Chaipang Math sells 3 in-app purchases, starting at $24.99 per month and Adaptus sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Chaipang Math ships an update fortnightly, Adaptus every 5 days. The most recent releases landed on September 30, 2026 and October 14, 2026 respectively.
