# TFIT vs U

The clearest difference is rating: U at 4.0 against TFIT's 3.4. U also leads on ads (none vs shown) and monetization model (free vs ad-supported). TFIT's advantage is review sentiment (27% vs 15%). On price, ratings volume, 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.

U holds the better App Store score, 4.0 against 3.4. Both are backed by a comparable volume of ratings — 455 and 507 respectively. Written reviews complicate that: 27% of TFIT's written reviews are positive against 15% of U's, so the app with the better star average is not the one people write more warmly about.

TFIT ships an update monthly, U fortnightly. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
