Useful... And stable

I have been using My Pie Interactive's Carpenters Helper but it crashes enough to make me a look for an alternate - this app right here.

It adds metric and imperial lengths together, very useful for Canadian users who work with metric codes and imperial lumber!

The app could use higher contrast for its interface, bit works well otherwise.
