We're always working hard to improve the app. Thanks for your 5 star review.
The administrator had made a quick response to the problems that I had with the app. Actually the problems I had , were my own mistakes entering the data.. Thanks

Hi, you need to enter the Ib (design current) in Amps, not kW as you have done. Current is measured in Amps, the Ib input clearly states "Amps". kW is a unit of Power, not current.
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).

Thank you for your feedback.
Most of the app is just to advertise other app for yet more money.

Hi, there are no 3rd party adds in this app.
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.

Its works better than any other app than i have found on here. The only issue is some of the writing overlaps on my phone
Developer reply
Hi, we hope the writing overlap on your phone is fixed in the current version of the app.
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.

Hi, the Ze and over-current protective device type and rating ARE required in a cable calculation to ensure the Maximum permitted Zs value is not exceeded, otherwise a larger cable size maybe required to satisfy the maximum Zs and disconnection time for the selected over-current protective device type and rating, see BS 7671 for further info...
Shame you can only have a cable with same size cpc as live conductor, especially when using swa and want to run a different size separate cpc.

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