Ratings and reviews

This is a very useful, time-saving app. Settings allows an easy switch between imperial and metric units Once appropriate circuit elements are id'ed using the app, it's easy to find a wire, fuse, or breaker, etc supplier appropriate for a diy'er or professional.

doesn't work on pixel 3, but works on pixel 5 and 6. Great for calculating wire gauge. Continues load would be a nice option for duration.

It doesn't calculate on android. just gives errors. pixel 3 plus.
