How to measure room temperature correctly

For accurate indoor temperature:

• Place your phone on a flat surface
• Leave it untouched for 3–5 minutes
• The reading stabilizes to actual room temperature

If your device has an ambient temperature sensor, the app uses it directly.
Otherwise, advanced calibration estimates the indoor temperature reliably.

Ratings and reviews

Absolutely great. I would have rated it 5 stars if it were not for the annoying long list of potential problems, how to calibrate, etc. that displays on the screen. You cannot see the room temp, and this list has no CLOSE (X) button in the upper right corner. I have to click GO BACK (<--) on my Android cell to see the room temp. (A real pain!) Otherwise, a really good app!

Seems the developers paid attention. There are not a lot of adds. A good balance I would say. Good job listening to your users. The app seems to work fairly well too. !)ETA 2/10/25 DOESN'T WORK ANYMORE. Every room is 69.5 whether they have been heated or not, this includes a deep freezer. The Feezer is really my litmus test at this point.

Incredible app! I've been searching for an app like this for a long time! It's pretty accurate on room temperature, about 2 degrees off but that might be because my phone is running a little warm. The outside temp right now is 102 degrees; this app says it's 104 degrees outside. I can't complain! It's the nearest and best of the best. 5 star app! Now if I can only get rid of that huge add right in center of the beautiful display!
