Google Play states that Body Temperature - Thermometer includes a calibration setting to fine-tune readings. The public listing does not document a universal offset, an exact menu path or a clinical conversion method. Follow the labels in the installed version, and do not treat calibration as conversion to core temperature.

Because screen labels can change between versions, use the control and instructions shown in your installed version rather than following an invented numeric offset.

Before opening the calibration setting

Confirm current eligibility on Google Play. The compatibility section currently names Watch 5 and 5 Pro; Watch 6, 6 Classic and 6 Classic Astro Edition; Watch 7; Watch 8 and 8 Classic; and Watch Ultra and Ultra (2025).

Samsung's current sensor documentation says skin-temperature tracking is available on the Galaxy Watch 5 series and later, and notes that Watch 5 requires Android 13 (API level 33) or later. The app listing specifically names Samsung Galaxy Watch models and does not name Pixel Watch or another non-Samsung model.

How should I use the documented calibration option?

Open the installed app and follow the calibration labels presented by that version. Google Play confirms that a calibration setting exists but does not publish its exact screen path or prescribe a universal number. This article therefore does not invent button names, offsets or a step sequence that the public source cannot verify.

What calibration means here

The public description says calibration can fine-tune readings. It does not describe calibration as a clinical method and does not say that it changes where the sensor measures temperature.

Samsung describes its Galaxy Watch tracker output as skin temperature and ambient temperature around the watch, and explicitly says this is not the same as body temperature. A calibrated app reading therefore remains a wrist skin-temperature reading.

What should you avoid?

• Do not treat calibration as a conversion to oral or core temperature.
• Do not copy an offset from another person or watch as a guaranteed medical correction.
• Do not use the result to diagnose fever or illness.
• Do not assume compatibility with a watch model that is not named on the current listing.

This app is not a medical device and is not intended to diagnose, treat, or prevent fever or any medical condition. Consult a healthcare professional for medical advice, diagnosis or treatment.

For context before changing any setting, read why wrist skin temperature differs from core temperature. The feature and compatibility overview covers the wider app listing.

Frequently asked questions

Where is the calibration option?

The current listing confirms a calibration setting but does not publish an exact menu path. Follow the calibration labels in the installed version.

What calibration number should I use?

The public listing does not prescribe one universal offset. Use only the adjustment interface in the installed app and do not treat any offset as a medical conversion.

Does calibration make the reading medically accurate?

No. Calibration does not turn wrist skin temperature into core temperature and does not make the app a medical device.

Where can I verify the latest app details?

You can view Body Temperature - Thermometer on Google Play for current features, screenshots and compatibility.
