# Kinsa vs Thermometer

The clearest difference is in-app purchases: Kinsa at none against Thermometer's 5. Kinsa also leads on rating (4.8 vs 4.4) and ratings volume (45K vs 24). Thermometer's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.5). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Thermometer sells 5 in-app purchases, starting at $6.99 per 7 days. Kinsa asks for nothing beyond the download.

Kinsa holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Kinsa has 45K ratings behind it against 24, so its average is the more settled of the two. Written reviews complicate that: 50% of Kinsa's written reviews are positive against 55% of Thermometer's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on November 11, 2026 and November 7, 2026 respectively.
