Why is it funny that their FAQ has an answer for Celsius? It's pretty much only the US that uses Fahrenheit for temperatures, the rest of the modern world uses celsius to display temperature. That coupled with the fact that Panic are a renowned Apple-based developer, should indicate really that there's likely no chance of getting a Panic-developed Android version.
It's really not trivial to those of us outside the US (Fahrenheit is meaningless to me), and enough US developers are US-centric enough that it sadly doesn't go without saying that they would support Celsius.
So... if you're an android developer, you know what product I want you to clone?
