# CO vs QiFitPro

The clearest difference is rating: CO at 4.5 against QiFitPro's 3.5. CO also leads on ratings volume (1.2K vs 45) and update cadence (fortnightly vs monthly). QiFitPro's advantage is iOS requirement (10.0 vs 14). On price, review sentiment, ads and in-app purchases 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 3.5. That said, the two scores are not equally well evidenced: CO has 1.2K ratings behind it against 45, so its average is the more settled of the two. Written reviews split almost evenly too, at 27% and 27% positive.

CO ships an update fortnightly, QiFitPro monthly. The most recent releases landed on October 27, 2026 and October 25, 2026 respectively.
