Works fine for laying out posts and such. Was looking for a free/ cheap app similar to inchcalc for ios and this was the best I found. Usable and accurate for what I've done. Only thing I miss is a memory function.

Sorry, it doesn't do square footage yet. It's been added to the GitHub page as a future enhancement. Thanks for the feedback!

Add vibration or some sort of sound so user knows if key has been pressed or not. But overall good.
