TempMate: Room Temp & Comfort

TempMate turns your phone into a practical room thermometer. See the current indoor temperature and comfort level of any room, track how it changes over time, and connect Bluetooth Low Energy (BLE) thermometers for live, measured readings.

Honest by design: Measured vs. Estimated

Most phones do not have a dedicated room-temperature sensor. TempMate never pretends otherwise. Phone-based readings are clearly labeled Estimated, and readings from a connected BLE thermometer are clearly labeled Measured. No exaggerated "always accurate" claims — you always know exactly what you are looking at.

What you get

• Live room temperature & comfort gauge — a clear Cold → Cool → Comfortable → Warm → Hot scale

• BLE thermometer support — scan, connect and read compatible BLE thermometers (Health Thermometer profile), with auto-reconnect. Pair any BLE thermometer you already own; the app is a neutral, open client

• Temperature alerts — get a notification when a room crosses the threshold you set

• History & charts — hand-drawn day, week and month graphs with min, average and max

• Multiple rooms — name and track each room separately

• Body temperature log — record readings manually with notes and measurement position (oral, forehead, ear, wrist, axillary). Note: this is a logging tool; it does not measure your body temperature

• Weather tab — outdoor conditions plus 24-hour and 7-day forecast via

• Settings — °C or °F, system/light/dark theme, calibration offset, font picker, weather-vs-comfort coloring

Your temperature history stays on your device.

Frequently asked questions

How accurate is the room temperature estimate?

Most phones lack an ambient temperature sensor, so the estimate depends on your device. For the best result, leave your phone idle and flat for a few minutes, avoid charging, and use the calibration offset to match a known thermometer. Every estimate is labeled as Estimated.

Can TempMate measure my body temperature?

No. A smartphone cannot measure body temperature without dedicated hardware. TempMate only logs readings you enter or readings received from a connected BLE thermometer.

Do I need a BLE thermometer?

No. TempMate works as a room thermometer with the phone alone. BLE support is optional, for when you want real measured data.

Is this a medical device?

No. TempMate is a general comfort and temperature-tracking helper. It is not a medical device and does not provide medical advice — for any health concern, consult a doctor.
