I've been an electrician for 14 years, this is a great tool/app to have on your phone

Very handy to have in your pocket. Great quick reference for sizing, fill, etc.
★★★★★Jennifer Yates· Feb 10, 2024
This is a lifesaver, even just for quick sizing of offsets, not to even mention the ease of rolling offsets!

Derate on the app is messed up, need to fix. Emailed him and no response and no update for the fix
★☆☆☆☆A Rob· Mar 30, 2026
Frustrating app. I don't know who designed this app, but it's trash. Will not do basic functions without you having to do backwards math to get the answer you need. I wanted to know what wire size I needed for a 20A circuit with derated for 10 current carrying conductors. It will not do it, it doesn't know how. All it gives me is that the circuit is derated to 10 amps, and you need 14ga wire. This app is stupid.
