# Keyboard AI vs Math

The clearest difference is ads: Keyboard AI at none against Math's shown. Math's advantage is update cadence (every 3 days vs monthly). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Keyboard AI sells 2 in-app purchases, starting at $7.99 per month and Math sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Keyboard AI ships an update monthly, Math every 3 days. The most recent releases landed on September 19, 2026 and August 18, 2026 respectively.
