Thermometer Room Temperature

Room Temperature Thermometer is your all-in-one digital thermometer, AI health assistant, air quality meter, and weather app, trusted by 1M+ downloads as a complete indoor thermometer and ambient temperature sensor.

INDOOR & OUTDOOR TEMPERATURE

The ambient sensor reads your indoor room temperature (place your phone flat with the screen off for about 5 minutes for the most accurate reading), while outdoor temperature comes live from the nearest weather stations using GPS or a manually chosen location. Every reading includes Feels Like temperature, a 0-100 Comfort Score, and one-tap switching between Celsius, Fahrenheit, and Kelvin, with calibration options for extra precision.

AI HEALTH TIPS

AI reads your real-time location, room temperature, AQI, and humidity, then delivers a personalized health tip on your home screen, like drinking more water, avoiding outdoor exercise, or opening your windows, in your own language, every day and every season.

SMART NOTIFICATIONS, FULLY CONTROLLED

Turn notifications on or off anytime, and choose your frequency: every 3 hours for real-time updates, every 6 or 12 hours for regular daily and morning/evening summaries, every 24 hours for a daily digest, or every 2 days for minimal alerts. Smart Alert Rules let you set your own AQI and temperature thresholds for instant alerts, with a live preview while you set them up.

AIR QUALITY METER

Track the Air Quality Index (AQI) with a full 24-hour history, plus detailed pollutant levels including PM2.5, PM10, CO, NO2, SO2, and O3, hour by hour.

HYGROMETER & BAROMETER

A built-in hygrometer shows humidity and dew point, useful for a baby's room, houseplants, or general home comfort, while the barometer shows air pressure in hPa and inHg. Wind speed and direction are shown alongside Feels Like temperature, and a UV Index and sunrise/sunset times are calculated for your exact location.

5-DAY FORECAST

Plan your week with a 5-day forecast covering temperature, humidity, rain, and wind.

PHONE TEMPERATURE

Monitor your device's own CPU and battery temperature in real time to help prevent overheating, alongside battery health, percentage, and voltage.
