# Celsius Thermometer Plus vs Thermometer

Celsius Thermometer Plus and Thermometer both sit at 4.7 stars, but that hides the real split: 87% of Thermometer's written reviews are positive against 38% of Celsius Thermometer Plus's. Thermometer also leads on update cadence (every 3 weeks vs every 7 months). Celsius Thermometer Plus's advantage is monetization model (ad-supported vs free with in-app purchases) and iOS requirement (13 vs 15.6). On price, rating, ratings volume and ads there is nothing between them.

Both are free to download. Celsius Thermometer Plus sells 1 one-off in-app purchase and Thermometer sells 10 in-app purchases, starting at $1.09 per month. Whichever you choose, the download price is not the number that matters.

Celsius Thermometer Plus holds the better App Store score, 4.7 against 4.6. Both are backed by a comparable volume of ratings — 54 and 132 respectively. Written reviews complicate that: 38% of Celsius Thermometer Plus's written reviews are positive against 87% of Thermometer's, so the app with the better star average is not the one people write more warmly about.

Celsius Thermometer Plus ships an update every 7 months, Thermometer every 3 weeks. Both last shipped on November 13, 2026.
