Human Steve ,

Master Plumber here, this app rules!

I read a plumber’s bad review just before making this one, he’s nuts....
I use this app every single day in the field. Makes life and plumbing so much faster. I love to be accurate, no stove piping on my watch! This Calc speeds things up and has opened my brain to a lot of stuff I never used before.
I do a lot of bending. (Well as much as I can get my hands on) and finding angles and offsets with this app is a total life saver and actually makes things most plumbers are scared to do, the most fun things to do!
I hated math for a long time but after using this I’ve taught myself a lot of new tricks and plumbing skills.
You just need to spend some time with the app, and really it’s not hard to use at all. I’d give it 15 stars but there’s only 5.

What a review! Thanks Steve!


Pipefitter review

I have been using Pipetrade Pro, both as an app and as the calculator, for well over eight years. I teach Advanced Offsets and tube bending. All student are given Pipetrade Pro calculators at the beginning of class. By the conclusion of the semester, all students have purchased Pipetrade Pro for use in the field. There isn’t a better tool for a Pipefitter.

Developer Response ,

Mr. Bendr, thank you for the review, we appreciate it and great that your students have options!

Sir Pipe ,

Back Button

I love this calculator! Makes my life a lot easier. The only thing I wish they had was a back button to erase any wrong inputs. Having to erase all my math for imputing the wrong button is kind of frustrating at times.

Developer Response ,

In your tools menu change your preference to Legacy Mode. This will give you your back button.
