Good content with the references to look at and calculators at the press of a button however my only gripe is that it’s a bit too expensive in my opinion. I have purchased it and intend to keep using it to make it up to myself but that’s just my opinion. Overall very good app for sparkys who need to calculate on the go.
10/10 App

I never ever ever leave reviews. But with this app I make an exception. This app is easily THE MOST USEFUL app I have ever owned. I use it daily and it has absolutely everything in one convenient place. If you are discouraged by the price let me tell you… if it was £50 I would pay for it just because of how useful it is. Amazing app and we’ll worth a purchase!

Had this app for sometime now and really recommend it for any electrician, engineer, trainee and designer. It provides a great level of information at the touch of a button and prevents having to carry reference books out on site.
Use it every day

A brilliant app and worth every penny. Concisely gives you the information you need when filling out certificates or doing on the fly cable calcs. I’d be lost without it
