# AI vs AB

The clearest difference is ads: AI at none against AB's shown. On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. AI sells 4 in-app purchases, starting at $9.99 per 7 days and AB sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

AI ships an update every 2 weeks, AB every 3 weeks. The most recent releases landed on October 27, 2026 and October 16, 2026 respectively.
