It’s ok, but needs some maintenance

The app is ok and could be great, however there’s some maintenance required.
I have noticed that when using the various antenna references, the measurements between mm, cm and m are not consistent and makes me doubt the app overall.

Why does it not do anything?

Err- is this meant to be a working app? Tried entering values in several calculators but nothing happens. Eg J pole calc and inductor calc. Only one seen working is resistor colour code. Not clear if this is a trial app which would explain issue.
