Verdict
The clearest difference is ratings volume: TK at 1.2K against mkk's 2. TK also leads on update cadence (every 9 days vs monthly). mkk's advantage is rating (5.0 vs 4.8) and iOS requirement (14.0 vs 18.0). On price, review sentiment, ads and in-app purchases 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.
mkk 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 68% of mkk's, so the app with the better star average is not the one people write more warmly about.
TK ships an update every 9 days, mkk monthly. The most recent releases landed on October 29, 2026 and October 19, 2026 respectively.
