Ratings and reviews

The conduit fill calculator is VERY temperamental, when attempting to scroll the screen. You must be very exact on where you touch the screen, or else, instead of scrolling the screen, you change one of the parameters in your plan. It might be more useful on a computer, but is tough to deal with on either of my phones.

Calculator is accurate, but CIC disclaimer needs to go. It takes up way too much space on the screen. I only get one conductor entry and have to scroll. More often than not, I end up selecting a cell entry rather than scrolling. And I cannot see all conductor data without scrolling. Very frustrating!!! Guess I'll have to look for another app....

It's easy to use and so far accurate . My only problem is with the scrolling. It is finicky about where you must touch the screen to scroll correctly. I would recommend this app.
