HORRENDOUS APP

DO NOT BUY. THIS IS A INSULT TO CHARGE FOR IT.

Not impressed

I have several ICertifi apps and find them good useful tools.
However for the price this app isn’t up to much there are free apps that do better.
Come on ICertifi for this money I would expect more complex calculations, including 3-phase calculations.
