# AI vs AB

The clearest difference is ads: AB at none against AI's shown. AB also leads on update cadence (every 2 weeks vs every 3 weeks). AI's advantage is iOS requirement (15.6 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. AI sells 3 one-off in-app purchases and AB sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

AI ships an update every 3 weeks, AB every 2 weeks. The most recent releases landed on November 9, 2026 and October 31, 2026 respectively.
