Allow me to be skeptical about the reliability of this algorithm. How can you ever know the temperature of the air outside by measuring the temperature of your pocket? Sure, there's a correlation, to some degree. But what if you wear different pants, or put the phone in your bag? I just don't see how that's possible (to a meaningful degree of precision). I would think data from weather stations would be a lot more reliable, and make the temperature sensor obsolete.

It presumably relies on having multiple phones recording the temperature, averaging out person-to-person variations in attire (thickness of pants, etc.). If those variations are correlated among people for a given day (everyone is wearing thicker pants), it's probably colder, and that would have to be included in the algorithm.

Wouldn't I know when I'd do that? For example, civilization has known for decades now how does a thermometer work. It will show correct body temperature only at a few places. If we can somehow isolate the sensor to not to read its own machine temperature but read the ambient temperature, I think it'll be a big thing.
