# Body Temperature Memo vs Thermometer Log

The clearest difference is rating: Thermometer Log at 4.8 against Body Temperature Memo's 3.0. Thermometer Log also leads on ratings volume (6 vs 1). Body Temperature Memo's advantage is in-app purchases (none vs 1) and review sentiment (67% vs 50%). On price, update cadence, ads and device support there is nothing between them.

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

Thermometer Log holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: Thermometer Log has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 67% of Body Temperature Memo's written reviews are positive against 50% of Thermometer Log's, so the app with the better star average is not the one people write more warmly about.

Body Temperature Memo ships an update every 3 months, Thermometer Log every 2 months. Both last shipped on September 21, 2026.
