For $1, its great

A study in function and minimalism, this app is great on a lot of fronts. Its very useful to have the results of previous calculations available for later review. I would like to see the app include scientific calculator features too - perhaps a scientific mode could be enabled in Settings. And really, we dont need an Equals button - this app proves that. At its current price of $3, Im not sure the value is there.
