Verdict

The call

The clearest difference is rating: Thermo at 4.6 against SensorBlue's 3.2. Thermo also leads on review sentiment (87% vs 46%) and update cadence (fortnightly vs every 6 weeks). SensorBlue's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price and device support there is nothing between them.
