Verdict
The clearest difference is review sentiment: TK at 72% against wellyou's 38%. TK also leads on update cadence (fortnightly vs every 3 months) and ratings volume (1.2K vs 2). 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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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 fortnightly, wellyou every 3 months. The most recent releases landed on September 22, 2026 and September 14, 2026 respectively.
