Verdict
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.

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.
