# TK vs wellyou

The clearest difference is review sentiment: TK at 72% against wellyou's 38%. TK also leads on ratings volume (1.2K vs 2) and update cadence (every 2 weeks vs every 3 months). wellyou's advantage is rating (5.0 vs 4.8) and iOS requirement (15.0 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.

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

wellyou holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: TK has 1.2K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 72% of TK's written reviews are positive against 38% of wellyou's, so the app with the better star average is not the one people write more warmly about.

TK ships an update every 2 weeks, wellyou every 3 months. The most recent releases landed on September 25, 2026 and September 14, 2026 respectively.
