Fever Thermometer 98.6°F

The app shows two values: body temperature, measured with an external thermometer (e.g. from Withings, compatible with the Healthkit (see Apple Store)) and with the Apple Watch 8, 9, Ultra, Ultra 2. These have a built-in temperature sensor. The last current values are displayed with the date. With the Apple Watch, the temperature (wrist) is measured while you sleep. Alternatively, you can also activate sleep mode during the day, at least 4 hours.
