Use this app almost daily, quick and easy solution for applying load to units in the field, eliminates the guess work.
Thank you for your efforts.

You download this app to test it. Was not minutes into testing and see what it can do that the message pops up in your face to pay. You haven’t even finished looking at a piece of it yet.

When you make it that annoying, the app is already garbage. You want to force people to pay before they know what they are getting. That is a sign.

Developer Response ,

The first 5 calculators are free to use.
And for unlocking the remaining calculators, you got to make a one time payment.
Once unlocked, the App works both in your iPhones and iPads.

Demand charge entry needed.

Very good application but Needs a field optional entry for "Demand Charge" for energy cost calculation. Energy cost calculator not useful for customers who are charged for kW demand without it. Other functions seem to work well.

Developer Response ,

Demand cost has been included in the latest version.
