What temperature is it where you are?

My thermostat is set at 16 degrees. I have gained 4 degrees from somewhere.

The Call of the Wendigo wrote:I think I've worked out how it works. It seems that every phone has a sensor that tells it how hot the battery is, in case it starts to overheat. I would assume that, when the phone's not in use, the battery settles down to room temperature and the battery temperature tells the app what temperature the room is.

It has a temperature sensor which it uses to detect overheat. The phone will cease operation until the device cools down. The sensor is not otherwise available to applications.

Measure the Temperature Wherever You Go
Thermometer is a free app for Android devices that measures the ambient temperature in any given space. Whether indoors or outdoors, Thermometer can measure the temperature wherever you go on a Celsius or Fahrenheit scale and display it in a number of ways. From the classic thermometer look to a digital or analog style, it?s accurate for any phone with an ambient temperature sensor. For phones without this sensor, the temperature displayed will be that of the phone itself and likely warmer than the actual ambient temperature due to heat from the battery. In this case, launching the app immediately after starting your phone will give you the best reading possible.
