Indoor Thermometer & UV Index

Is it really hot, or does it just feel that way? Indoor Thermometer & UV Index is a thermometer app that shows your indoor temperature on a 3D e-ink display and the outdoor temperature on a classic dial thermometer, with the UV index and simple advice on when to open or close the windows.

INDOOR TEMPERATURE

• Most accurate after the phone rests on a table, unplugged, for a few minutes
• Measure again any time: keep the phone still for 10 seconds
• Estimated indoor humidity and feels-like temperature

WINDOW ADVICE
• Compares your indoor temperature with the hourly forecast
• Tells you when to open the windows for a cooler breeze, and until what time

GOOD TO KNOW
• The indoor reading is an estimate based on the battery temperature. It is not a medical or laboratory thermometer and cannot measure body temperature.
• While the phone is charging or in your hand, the battery runs warmer than the room.
• Your approximate location is used only to get the forecast where you are.
• Free. No account needed.
