User Reviews

Users praise the app as a very useful, accurate, and fast voltage-drop calculator that’s easy to use and handy for on-site verification. It helps explain results to clients and supports AC/DC work. Recurrent drawbacks include UI/UX problems with the agree button, poor screen scaling on phones, feature gaps like no 3-phase mode and no 16 AWG option, and concerns about cloning/licensing. Overall it’s a valuable tool when interface and feature gaps are addressed.

Pros

Very useful and accurate voltage drop/design tool
Easy to use with a clean, to-the-point interface
Handy on-site tool that helps verify conductor performance and explain results to clients
Fast performance and versatile for AC and DC work
Reduces guessing and provides quick, reliable numbers for quick decisions

Cons

Agree/acceptance button placement blocks access to the app (UI issue)
App appears to be a clone and raises licensing concerns
Doesn't fit or scale well on phone screens (UI responsiveness)
Lacks 3-phase calculation capability
Missing 16 AWG option

works perfectly, I do have a suggestion though. It would be helpful if it would give information on how much to up size the ground wire. Even if it is just circular mill difference in wire being calculated.
