Good but popup annoying

Great app and been using it for years but latest update is annoying as popup advising update to ver 11 is in version 11

Based on AWG cables

If you are in the USA this will probably work for you.
Try to work out volt drop in AWG in metric Europe / UK
After paying for the supposed 50 calculators, in less than 3 mins the app was trying to sell me 16 more!
I want my money back.
In a word - disappointedIn a word - disappointed

This app is really bad . I don’t like it

I lost my money

No impedance calculators

Am I blind or is there not a single impedance calculator in the bunch? The other calculators are great but I can’t give this app 5 stars without there being any impedance calculators on here.
