To me this why the iPad gen8 is the ultimate tool, this application is mind glowingly good, it does everything from schematics to led circuits to oscilloscopes. If you are any kind of electrical engineer this is an absolute must as everything’s in one convenient place!You can even test your circuits before building them on a pcb, this is the best £7.99 I have ever spent, it’s laid out beautifully and there’s literally every tool under the sun onboard the app.

I am a electronic hobbyist and find myself using this app more and more. The tools make designing simple circuits a breeze with tools to help you select the exact component and values required for a given variable like voltage or current etc.Really appreciate the hard work that's gone into this and really like the recent update. Go Pro you won't regret it.

The amount of info on the pro version is amazing.Get the free version, have a play and I’m sure most of you will buy the pro version (especially for the price).I do find I much prefer using it on my iPad than my iPhone though

This is the sort of app that demonstrates the power of iDevices. It is a must have just for day to day calculations. I'm old enough to have started design using a slide rule that cost a weeks salary - this app costs about 11 mins of my income.

Did electronics at basic level years ago and now I have found an app that allows me to rekindle a passion I thought I had lost.

This does way more than I need (but hey... who knows what I might fiddle with in the future?)So easy to use, so nicely presented and insanely thorough!Just deleted 4 other apps I don’t need any more...
