Outstanding product and outstanding support

I’ve been a subscriber to BuildCalc for many years, maybe as many as 15 but I honestly can’t remember. The software and app performs as it should but the advanced features is what sets this product apart. It’s difficult to put into words as there are too many to list. If I’m performing a calculation that I haven’t completed in a long time or if it’s a new calculation I’ve never attempted the app/software has a function that allows you to hold down any desired key and it will open a background to explain the function and its uses. When this doesn’t work I have reached out on a few occasions and I was always answered promptly with a solution to my problem. I recently found a bug (as all apps have) and the owner reached out for a meeting in which we shared screens and attempted to replicate the problem. This shows the amount of buy-in the company has in their product and customer service as well as their desire to continue to be THE platform for job site calculations.

Construction Foreman

I work in the film and movie industry and have been using Build Calc for over 13 years. Some your favorite movies like Spider-Man, Guardians of the Galaxy, Vennom, Black Panther and many many more have benefited from the use of this app. I have made several recommendations to the developers for improvements and additions and they add them. Hands down, you want professional results, use the apps that the Pros use.

I purchased build calc several years ago, it is something I feel every Carpenter should have in their pocket.
I love the blueprint features it offers. It makes clear prints to send easy.

Also. I originally purchased this on my Samsung, and transferred to iPhone over the holidays. I sent an email with my recipes to Ben, an within 5 mins I was sent back a code.

Exceptional app and exceptional service.
