Verdict

The call

The clearest difference is price: WeatherBlend at Free against Thermo's $3.99. WeatherBlend also leads on review sentiment (100% vs 77%). Thermo's advantage is ratings volume (1.9K vs 2) and chart position (#81 vs unranked). On rating, update cadence, ads and in-app purchases there is nothing between them.

WeatherBlend is free to download; Thermo costs $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

Thermo holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Thermo has 1.9K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 77% of Thermo's written reviews are positive against 100% of WeatherBlend's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Thermo ships an update every 6 days, WeatherBlend weekly. Both last shipped on October 24, 2026.
