Incredibly Useful and Efficient

I do a lot of radius woodwork. This app saves me from waiting until I get back to my desk to figure out the radius of whatever project I'm producing.
I recommend this to anyone in construction. It surely has other uses as well for other trades.

Very, very basic app

There are no settings and no graphical representation - all you get is a table with 2 input fields for width and elevation and it gives you 4 results in your selected units.
Very, very basic app.
The description refers to the calculated "centre angle" being an estimate - but it does not provide a definition or any identification of what they are calling the "centre angle".
I expected more, even if this were a free app I would still feel disappointed.
