Do not buy.

App crashes after inputting the very first project name. Do not buy this app.

No updates

Developer does not take care of this app there are no updates it feels like you’re working with a Calculator. I got a new phone and lost all of my loads that I have done in the past there’s no way to export them out. Software is hard to use and not intuitive recommend going to right soft mobile

Useful app!

I’ve been using this app for years, and it’s very useful. The update is even more so with the Equipment Locator built right in. Even though it’s not a full ACCA Manual J8 app, it’s good enough for me to do fairly accurate loads out in the field. I like the reporting, too.

Great app!

Disappointed

Bad that it only does 1000 sq ft . Few home are that small. Makes you do room by room then put them all together for total

Cool App if you are into OK

Several quantifiers are a bit enigmatic for this App. For those like me who avoid customer service, I will need more time to establish confidence in its recommendations. Regardless, it is a very helpful program.
