Imperial measurements option?

Im excited about this app, as I love soft yolks and dont much care for hard-boiled, but I havent yet gotten to try it with a real-life egg, so Im tentatively giving the app a three.

To all the people who are having trouble with overcooking, did you set your altitude correctly? Water boils at a lower temperature at higher altitudes. For example, I live in Tulsa, which isnt exactly the roof of the world, but my water boils almost four degrees cooler than at sea level. Significant with something as finicky as an egg.
