# Thermo vs SensorBlue

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.

Both are free to download. Thermo sells 10 in-app purchases, starting at $1.09 per month. SensorBlue asks for nothing beyond the download.

Thermo holds the better App Store score, 4.6 against 3.2. That said, the two scores are not equally well evidenced: Thermo has 129 ratings behind it against 14, so its average is the more settled of the two. Written reviews point the same way: 87% of Thermo's written reviews are positive against 46% of SensorBlue's.

Thermo ships an update fortnightly, SensorBlue every 6 weeks. Both last shipped on September 23, 2026.
