# CyFit vs Lefun Pro

The clearest difference is rating: CyFit at 2.9 against Lefun Pro's 2.2. CyFit also leads on iOS requirement (11.0 vs 15.0). Lefun Pro's advantage is ratings volume (49 vs 11). On price, review sentiment, update cadence and ads there is nothing between them.

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

CyFit holds the better App Store score, 2.9 against 2.2. Both are backed by a comparable volume of ratings — 11 and 49 respectively. Written reviews complicate that: 0% of CyFit's written reviews are positive against 5% of Lefun Pro's, so the app with the better star average is not the one people write more warmly about.

CyFit ships an update monthly, Lefun Pro fortnightly. The most recent releases landed on September 15, 2026 and September 17, 2026 respectively.
