I'm a hvac/r student and right now taking blue print reading this helps me out and got me through a test far faster then the rest of the class. This also helps me in the field with trying to figure out if the roof top unit can fit or if the furnace will fit in the space



Love this app. Does all of the calculations i need in ft & in. It is so good I upgraded to Pro to support this free version. Little did I know that Pro has a ton more features beyond just a calculator! Btw the tutorial button is the '?' towards the top not under any ad.

Love it!


This app is perfect for me i am in the landscaping industry. I am disappointed with the ads. There should be a pro version with no ads.
