  • Please metric wire size (mm2)

    My best app on AppStore

  • Does Not work with iOS 7

    by Le Moch

    CI should fix this before they launch iOS 7 GM

  • Great Electrical Technical App

    by YellowJacket83EE

    I have owed the hand held calculator for years and I swear by it. I am able to design wherever I am with this. The price is well worth it. My ability to solve client issues on the spot only enhances their faith in me. There is a slight learning curve, but once you learn the process, it will be seamless.

  • Just like the handheld Device

    by Harley1234554321

    I have been waiting for this to come out for a long time. I have been searching for it quite often. This app operates just like the real thing. Thank you for finally offering it. It does everything I need it to do. The original device does not do conduit fill but it would be a good addition. I texted a friend of mine that the app was available and he also downloaded it within 1 minute of the text. Thank you, Thank You.

  • Excellent!!!!

    by JDelgado1977

    Great Electrical calculator!! The interface is not retina display optimized jet, so is a bit blur. Otherwise would be 5 stars!

  • Great calculator!!

    by vemotorsports

    Just like the handheld version only on my phone! If you do design build work, you need this calculator it will save you hours of paperwork and math by hand. Will calculate voltage drop, amperage conduit and wire size, you name it. Highly recommend. And great support.
