1/5Not good.
First pipe fitting app. I pay for. Looked great. Appearances are deceiving though,, the items i do need the info on. It says that they are not on the DATABASE. The ones that are available. They are also on the free apps. This was a total waste of my hard earned money.

4/5Please update app to remove background grid lines.
Great app and super helpful. After the most recent update, background grid lines are too visible. Make it hard to read dimensions and other text. Please update! This is on an iPhone 7 plus. Will give deserved 5 stars when grid lines go back to how they used to be.

4/5Great little piping app
After a week of use while checking a job, I love the way the calculator works integrating piping components and being able to continue a dimension string from catalog to calculator back and forth. This is so handy compared to spinning the old piping wheel! The calculator itself needs some attention with the store and recall functions not working like a real calculator. Clear button also needs to clear only the last input mistake, not everything! Frustrating when making a mistake along a string of dimensions and having to start over. I recommend to pipers trusting the app will continue evolving. June 2017 update improved the app more!

5/5Awesome piping design & engineering reference APP.
Totally helpful. I use this APP almost everyday. Thanks to the person that developed this as It has been long overdue. It has helped me become the full and complete piping designer I could expect, with all the info. it provides. Very inexpensive and worth every penny. A must have for every piper. People pay tons of money for piping design products. But this $9.99 spent is a tremendous value. I can't say enough about it really.

5/5Outstanding
Thanks to Jean Pierre for creating such a user friendly app for those of us looking for quick info while conducting field work. This app let's you have less things to worry about in the field and puts a plethora of data at your fingertips that would otherwise take a binder or multiple books to equal. Worth every penny!
