Great little electrical watts amps calulator 1 , 3 pahse with power factor

Noticed some reviewers like snap dragon are purposly writing bad reviews . This app works 100 percent .This is a very useful little app, it works out all the single pahse three phase watts , amps and voltage results from any combination with a power factor setting, all can be set and saved in a settings area which is very useful. Very nice interface simple to use.

Would recommend to any electrical contractor on the move, plus it is a UK developer. more updates.
