Best App Ever 5 out of 5.0
User: , Architect from Salt Lake City, Utah
User Rating: ★★★★★
I have had a Construction Master Pro Calculator since 1990, when I wanted to replace it around 2009, I bought an i-phone just so I could have this app! I love this app and it's the only one I need to buy.

Greetings! Android customer here. Just downloaded Construction Master Pro. I'm actually an artist, and its what I've been looking for for quite some time to help me accurately upscale my works from small sketches much larger works. My review is 'I love it!'

This is one of the best apps I could ever have on my phone. I have used several of these calculators over the years on a daily basis, but now I carry it with me wherever I go. One of the best tools I own!

This calculator works just like the hand-held units we all rely on. I tried several other construction specific calculators available for the iPhone/iPad, but found them all clunky and confusing. I think I’ll stick with what I know.

Finally ... Have had the standalone in the shop for years, now have it on my phone. There is nothing better on the market, in any form! Thank you, Calculated Industries!

I had been waiting for this app. I have had many Construction Masters over the years and love the format. Now with the app on my phone I never am without it. The format is just like the hand held units so nothing new to learn. Like the heading says it is worth the money.

great product! 5 out of 5.0

I use the original Construction Master Pro in my remodeling business for rafters, stairs, squaring foundations, etc., so this was the first App I downloaded to my iTouch! I just started to use it, but it looks and feels like the real thing-- no learning curve.
