Ratings and reviews

Unusable! Should be taken off the Play store! On start up, the app takes GPS coordinates and uses that info, even if you enter a different jobsite address. It also ignores fuel type likely based on the apps GPS location. Loading a high resolution picture, blows away the screen form's formatting, losing almost any chance of propper data entry. Overall, a waste of my time that I'll never get back! a very poor reflection on the company trying to promote its product.

Personal information harvester. Tries to get you to create an account and divulge location, addresses, names, contact information when none of it is relevant to the task of sizing a heater. I gave up without a useful result.
