Just what I needed

Wiring diagrams are excellent. App is well worth the money. Voltage drop calc was very helpful in figuring out the correct size wire for welder outlet in my garage.

A must have!!

Calculators work great for use at my job. Ive doubled check calc answers by hand and impressed they are just as accurate. Definitely saves me some time for those quick calcs. Looks slick with the new retina display on my iPad :) A++

Not enough info, too lame

I think this developer is trying to make money without going through developing a good app. He just cut and paste few light circuit images and asking 5.99 for it. As of the app it is worth maybe 99 cents. Hey developer add more info about house wiring, how about all the other electrical wiring info in residential houses? My suggestion to anyone who wants to buy this app is don't. unless of course the developer adds more info. Much much more info into the app for the app to be worth 5.99. I am sorry for myself wasting my time even writing this review. I felt like I am robbed, literally. If the dev update the app with more stuff then I can come back with a follow up review.
