Indoor Thermometer & Weather

ROOM TEMPERATURE, WEATHER AND EVERYDAY PLANS
Track indoor readings from compatible sensors or manual entries, and explore detailed local weather. Use the new Best Time widget to check windows for airing rooms, drying laundry and watching the Moon.

MONITOR INDOOR CONDITIONS

Connect compatible Bluetooth Low Energy temperature and humidity sensors to view live readings from multiple rooms. Name each sensor, switch between rooms, and keep a local history of temperature and humidity changes.
You can also add readings manually and explore practical reference methods when a sensor is not available.

EXPERIMENTAL ACOUSTIC THERMOMETER

Estimate air temperature using the speed of sound and an echo from a nearby wall. ThermoWeather runs several measurements, adjusts for humidity, and shows the estimated uncertainty instead of presenting the result as an exact sensor reading.

SMARTER HOME COMFORT

Compare indoor sensor data with outdoor weather. The ventilation advisor uses temperature, humidity, and dew-point calculations to help you decide when opening a window may improve indoor comfort.

FLEXIBLE TEMPERATURE TOOLS

Multiple BLE sensors and room names
Celsius and Fahrenheit
Automatic sensor logging
Manual room and body temperature records
Manual notes and measurement sources
Several thermometer display styles

Custom units for wind, pressure, distance, precipitation, and wave height

MOON PHASES AND NIGHT CONDITIONS
Explore the moon calendar, phase, moonrise and moonset. Compare viewing windows using Moon position, cloud cover and darkness. Check the northern lights map and Kp activity alongside conditions for your selected night. Visibility is not guaranteed.

PLAN AND LISTEN
Check airing, laundry-drying and moon-watching windows in the Best Time widget. Follow your airing timer on the Lock Screen with Live Activities. Listen to the forecast for a selected day, customize your home screen blocks and share a reading or planning window.

THERMOWEATHER PLUS

Upgrade to Plus for the full 14-day forecast, monthly outlook, weather history, extended marine forecasts, ventilation advice, severe weather notifications, and an ad-free experience. Plus also unlocks more lunar dates and night comparisons.

IMPORTANT

ThermoWeather does not directly read room temperature from an iPhone ambient-temperature sensor. Indoor readings require a compatible BLE sensor, manual input, or the experimental acoustic estimate.
The acoustic method is an estimate and may have a significant error depending on distance, room acoustics, noise, and measurement setup.
Body-temperature records are manual and intended for personal logging and informational use only. ThermoWeather is not a medical device and does not diagnose, prevent, monitor, or treat any medical condition.
