If you know a bit about use electricians calculators or are willing to learn, this app will save you time. It has up to date NEC references and can point you in the right direction for all of its calculations to allow you to verify accuracy. I highly recommend. ### 5/5 — Excelente *2021-01-01, version 1.6.2* Poderosa herramienta que contiene datos de muchas tablas del NEC y permite hacer cálculos de circuitos, selección de cables, caídas de tensión, interruptores, cableado y proyección de motores, etc. La uso desde hace muchos años y la recomiendo absolutamente. ### 3/5 — Abbreviation *2020-10-30* Abbreviation on the keys for cell phone use makes it hard to know what the buttons do for me maybe make a hover option over the key would give you the full description on a landscape verses portfolio **Developer response:** Thanks for the feedback. We will look into adding this functionality into a future update. ### 1/5 — It’s awesome except I have to restart the app many times to get it to calculate *2019-11-14* Wish this issue could be fixed ASA!! Seems the equal sign does t work? **Developer response:** Please contact us at techsupport@cyberprodigy.com so we can assist in resolving the issue you are having with your device. ### 1/5 — Just dead wrong *2018-08-04, version 1.6* Can’t even compute Ohms Law correctly. A 9 watt LED bulb draws .075 amps at 120 volts. This app says that a 9 watt, 120 volt bulb draws 0.043 amps. I’m sure not going to use it to calculate how many 9 watt lightbulbs I can put on a 15 amp light switch ### 3/5 — Needs updating *2016-12-19* This app was last updated in 2013 and needs to be brought up to date. I would not buy it unless this is done. This is a useful app, particulary if you use it regulary so you know all the key strokes. It has a fairly steep learning curve becasue entering date typically requires memorizing the many key required. ### 1/5 — Over priced *2015-02-14* They could have made this much easier to use by just adding more pages and tables. You can find the info you want in a nec codes book faster than you can input all required info into the app, assuming you remember how and don't have to go back and read manual. ### 3/5 — Uneccesarily Complicated *2014-12-02* This is not intuitive - it works but you have to have the manual in front of you to be able to get the right key strokes to make it work. Not worth the money in my opinion. For $20, you should be able to come up with something not so cryptic. I will use it for derating because I have not found anything better but there are much better apps out there for sizing conduit and voltage drop in my opinion. ### 5/5 — Amazing app *2014-05-21* By far the best app available for electricians. Handy little tool, use it all the time. Once you get familiar with the buttons it's quick ### 5/5 — Absolutely superior *2014-01-23* This app is by far the best electrical tool I have ever used. It is current to the NEC standards and even lets me set to whatever NEC year standards I want to calculate by. The large help manual is very useful and I love that I don't have to carry around an extra physical calculator with me. ## Frequently asked questions about Electrical Calc Elite ### What does the Electrical Calc Elite app do?
