# CO vs AICare Pro

The clearest difference is rating: CO at 4.5 against AICare Pro's 2.4. CO also leads on review sentiment (27% vs 9%) and ratings volume (1.2K vs 165). AICare Pro's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, update cadence, 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.

CO holds the better App Store score, 4.5 against 2.4. That said, the two scores are not equally well evidenced: CO has 1.2K ratings behind it against 165, so its average is the more settled of the two. Written reviews point the same way: 27% of CO's written reviews are positive against 9% of AICare Pro's.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
