# TornadoSpy vs Thermometer

The clearest difference is review sentiment: TornadoSpy at 69% against Thermometer's 17%. TornadoSpy also leads on update cadence (every 2 months vs every 6 months) and price ($1.99 vs $2.99). Thermometer's advantage is rating (4.0 vs 3.8). On ratings volume, ads, in-app purchases and chart position there is nothing between them.

TornadoSpy costs $1.99 and Thermometer $2.99 up front. TornadoSpy sells 2 one-off in-app purchases and Thermometer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Thermometer holds the better App Store score, 4.0 against 3.8. Both are backed by a comparable volume of ratings — 12 and 5 respectively. Written reviews complicate that: 69% of TornadoSpy's written reviews are positive against 17% of Thermometer's, so the app with the better star average is not the one people write more warmly about.

TornadoSpy ships an update every 2 months, Thermometer every 6 months. Both last shipped on October 23, 2026.
