# Temtop vs Airdog

The clearest difference is update cadence: Temtop at every 5 weeks against Airdog's every 19 months. Temtop also leads on rating (2.9 vs 2.6) and ratings volume (82 vs 18). On price, review sentiment, 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.

Temtop holds the better App Store score, 2.9 against 2.6. Both are backed by a comparable volume of ratings — 82 and 18 respectively. Written reviews complicate that: 32% of Temtop's written reviews are positive against 34% of Airdog's, so the app with the better star average is not the one people write more warmly about.

Temtop ships an update every 5 weeks, Airdog every 19 months. Both last shipped on October 24, 2026.
