I love this handy app! Makes having to remember formulas a little forgiving, considering I can only remember two or three. Simple and easy to use. And free. Much rather have it and not need it than the alternative.

Apparently from the annoying ads that now pop up I've been using this app over several phones and I've found it very useful for UHF and microwave.
