Body Temperature - Thermometer is a standalone Wear OS app by HSN Softs for reading wrist skin temperature on the Samsung Galaxy Watch models listed below. The app is designed around a simple idea: open it on the watch, start a reading with one tap, and view the result while the developer's Google Play declaration states that the app does not collect or share temperature data.
This is a wrist and skin temperature utility, not a clinical thermometer. It is important to understand both what the app does and what it does not do before using its readings.
What does Body Temperature - Thermometer do?
Body Temperature - Thermometer reads the skin-temperature sensor on the Samsung Galaxy Watch models listed below. It displays a skin temperature reading from the wrist and lets you switch between Celsius and Fahrenheit. The app also includes a calibration setting for users who need to fine-tune how a reading is presented.
The Google Play listing identifies the app as an accepted member of the Samsung Health Partner App Program. This allows the app to use the supported watch temperature sensor through authorized access. That partnership does not turn the app or the watch into a medical device.
Quick access on Wear OS
Because the app is built for the watch, you do not need to open a companion phone screen to begin a check. Its Wear OS Tile can place quick access near the watch face, while complication support can surface the app from a compatible watch face. The app is described as fully standalone.
The core feature set is deliberately narrow:
- One-tap wrist and skin temperature readings
- Celsius and Fahrenheit display options
- A calibration setting
- A Wear OS Tile for quicker access
- Watch-face complication support
- Standalone operation on the watch
Which Galaxy Watch models are listed as compatible?
The current Google Play description lists the following Wear OS models:
- Samsung Galaxy Watch 5 and Watch 5 Pro
- Samsung Galaxy Watch 6, Watch 6 Classic and Watch 6 Classic Astro Edition
- Samsung Galaxy Watch 7
- Samsung Galaxy Watch 8 and Watch 8 Classic
- Samsung Galaxy Watch Ultra and Galaxy Watch Ultra (2025)
Compatibility is limited to the Samsung Galaxy Watch models listed above running Wear OS; the store listing does not claim support for Pixel Watch or other Wear OS devices. A phone by itself cannot provide the wrist sensor reading described here.
Does the app collect temperature readings?
According to the current Google Play data-safety declaration, the app does not collect data and does not share data with third parties. The product description says temperature data stays on the wrist. This may appeal to people who prefer a focused watch utility instead of a broader health-profile app.
Is it a fever thermometer or medical device?
No. Body Temperature - Thermometer measures skin temperature at the wrist. Skin temperature can differ from core body temperature and can be influenced by the environment, watch contact and other conditions. The app is not intended to diagnose fever, treat a condition or replace a medical thermometer or professional medical advice.
If you need a clinical temperature measurement or are concerned about symptoms, use an appropriate medical device and contact a qualified health professional.
Who is this wrist temperature app for?
The app is best suited to owners of a listed Galaxy Watch who want a direct, uncomplicated view of the watch sensor reading. It may be useful when you want to check a wrist temperature value during everyday activities such as work, exercise, sleep routines or travel, while keeping the result on the watch.
Frequently asked questions
Can a Galaxy Watch measure wrist temperature?
Supported Galaxy Watch models include a temperature sensor. Body Temperature - Thermometer reads that sensor and displays a skin temperature value on the watch.
Can I change from Celsius to Fahrenheit?
Yes. The app includes a one-tap switch between Celsius and Fahrenheit.
Is wrist skin temperature the same as core body temperature?
No. Wrist skin temperature is not the same as core body temperature. The app is intended to show a skin-temperature sensor reading for general information, not to diagnose fever or a medical condition.
Does it work without a phone app?
The listing describes it as a standalone Wear OS app, so its temperature-checking experience runs on the compatible watch.
Where can I inspect the app?
You can view Body Temperature - Thermometer on Google Play to check the latest compatibility notes, screenshots and app information.
