Just curious if there is an app that can turn the Droid into a temperature gauge?
I don't think this would work at all
You basically have to options:
1. Droid's temperature gauge
2. External temperature gauge
Anything used to measure temperature on the Droid itself would be considerably affected by the hardware, giving inaccurate readings. So you're basically left with pulling from outside sources such as Beautiful Widgets and WeatherBug
