Body Temperature - Thermometer is described on Google Play as a fully standalone Wear OS app. Its measurement experience runs on a compatible smartwatch and reads wrist skin temperature from the watch sensor, so you do not need to open a companion phone screen to take a reading.
Body Temperature - Thermometer is a Samsung Health Partner app for checking wrist skin temperature on supported Wear OS watches. It shows readings in Celsius or Fahrenheit and includes calibration, a Wear OS Tile and complication support.
What does standalone mean for this Wear OS app?
In the current listing, “fully standalone” appears alongside “skin temperature readings straight from your watch sensor” and “built for Wear OS.” Together, those statements describe an on-watch measurement flow rather than a phone-based thermometer interface.
The listing does not document every installation or pairing step. A watch may still use the normal Google Play and Wear OS setup process. The supported claim is narrower: once the app is available on a compatible watch, the listed measurement features are designed to be used from the watch.
Which features are available directly on the watch?
The current Google Play description lists one-tap wrist skin temperature measurement, Celsius and Fahrenheit units, calibration, a Wear OS Tile and complications. It also says readings come directly from the watch sensor.

Does standalone mean every Wear OS watch is compatible?
No. Standalone operation and hardware compatibility are different questions. The app needs a supported watch with a temperature sensor. The current listing names Galaxy Watch 5, Watch 5 Pro, Watch 6, Watch 6 Classic, Watch 6 Classic Astro Edition, Watch 7, Watch 8, Watch 8 Classic, Watch Ultra and Watch Ultra (2025). Compatibility with other models should not be inferred.
Check the live Google Play page from the account connected to your watch before installing because device availability can depend on the watch model and current store compatibility.
Is this a medical thermometer?
No. The app measures skin temperature at the wrist. The current listing states that it is not a medical device and is not intended to diagnose, treat or prevent fever or any medical condition. Do not interpret an on-watch wrist reading as a diagnosis or as a substitute for medical care.
