User reviews

Meh

Not worth it. Try something else.

Not for residential

App isn't for residental. 9 rooms for a 1500sqft home is ridiculous.

Please give me a refund

Garbage

Doesn't work as advertised. Calculations are wrong and the app is almost unusable.

The name says it all

This is a quick load calc app, not one to do those detailed loads required by the city. It’s perfect for those rule-of-thumb loads I need to do so often. It’s cheap, very easy to use, and most likely within 10 to 15% of doing a real load calc. I like it!

Not for residential use

This app has been a sad disappointment of what little it can do. I feel ripped off and want my money back!
