# Thermometer vs HS

The clearest difference is rating: HS at 5.0 against Thermometer's 4.4. HS also leads on in-app purchases (none vs 1) and ads (none vs shown). Thermometer's advantage is review sentiment (30% vs 0%) and ratings volume (4.2K vs 1). On price there is nothing between them.

Both are free to download. Thermometer sells 1 one-off in-app purchase. HS asks for nothing beyond the download.

HS holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Thermometer has 4.2K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 30% of Thermometer's written reviews are positive against 0% of HS's, so the app with the better star average is not the one people write more warmly about.

Thermometer ships an update every 2 months, HS every 3 weeks. The most recent releases landed on September 29, 2026 and September 16, 2026 respectively.
