# Klima vs TK

The clearest difference is rating: Klima at 5.0 against TK's 1.4. Klima also leads on review sentiment (74% vs 64%) and iOS requirement (13.0 vs 18.0). TK's advantage is ratings volume (15 vs 1) and monetization model (free vs ad-supported). On price, update cadence, ads and in-app purchases there is nothing between them.

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

Klima holds the better App Store score, 5.0 against 1.4. That said, the two scores are not equally well evidenced: TK has 15 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 74% of Klima's written reviews are positive against 64% of TK's.

Klima ships an update every 4 weeks, TK every 5 weeks. Both last shipped on October 25, 2026.
