# I vs Cognitivebotics

The clearest difference is update cadence: Cognitivebotics at every 3 weeks against I's every 10 months. I's advantage is iOS requirement (11.0 vs 15.3). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

I ships an update every 10 months, Cognitivebotics every 3 weeks. The most recent releases landed on October 13, 2026 and October 4, 2026 respectively.
