I have only had a quick play, and the app itself is fine. What let's it down for me are the following. On opening the app you are greeted with, what I can only describe as a sales pitch for more products, when I open the app, I just want it to open, and not other things that are for sale. This could be me missing something and not the app, but It doesn't seem to have the option to add a logo or company details, which would be nice, and look more professional, as well as changing the colour.

Pro's 1. I like the layout of the app, it is formatted in a logical order. 2. Easy to use, especially onsite for a quick check. 3. App support are very helpful, I had a problem and they emailed me at various times of the day and evening. 4. Like the option to print out a document with the design and circuit data. Cons 1. Can't see an option to save circuit details. 2. Text overlapped on results sheet . However, easily sorted by reducing display font size ( support team solution to this).

Asks for too much data before calculating. It's very difficult to calculate the initial cable size, as it asks for way too much data. For example, it asks for Ze(Impedance) and Protective device rate, when it is not needed. For example, I simply run cable from transformer to the building electrical panel. If you simply need to calculate size of the cable based on kW or Amp total, all these data is not necessary and not needed. The other application from Ettoire Group is much better.

Nice easy to use calculator, would be nice if you could add a separate CPC for distribution circuits but not a deal breaker.

Thanks for your quick respond but I have worked out size of cable myself so It's fine 3 stars for quick respond But not impressed with the App Needs to be more simple.
