Customer Reviews

Very Helpful

As a person with no real formal electrical training I find this app very helpful. It has saved me hours of reading on my own, and breaks the math formulas down so they are simple to understand. Info on downloading datasheets would be helpful as another reviewe mentioned. As with anything room for improvement, and with these guys, I'm sure there will be. Thanks Collin and LadyAda!

Too cool for words

But here they are. You can't do layout but an iPhone doesn't have half a gig. What it does do is make the thought process easier. On the road, too. I just wish there was more documentation on how to pull datasheets. But that's not a knock, just a wish list sort of thing. Can we do that, daughter of Babage ;-)

great app

A lot of small useful tools that will keep things simple. One thing that could possible be improved is, instead of a full keyboard for number inputs have a simple number keypad.
