Verdict
The clearest difference is review sentiment: @Thermometer at 75% against Celsius Thermometer Plus's 38%. @Thermometer also leads on update cadence (every 6 weeks vs every 7 months) and chart position (#197 vs unranked). Celsius Thermometer Plus's advantage is rating (4.7 vs 4.5) and monetization model (ad-supported vs free with in-app purchases). On price, ads, in-app purchases and device support there is nothing between them.
