Piping Design app for Android

Hi, I just created an app called "Pipeflex" and I want to share it with you guys.
It come in two versions: FREE and PAID (PRO).

With this app you can calculate the pipe thickness, the stresses due the piping flexibility, pressure vessel shell and head, and so on.
In the future I'll implement a FEM (finite element method) to calculate the stresses, just like CAESAR does (not eexactly..)

Anyway, I hope you guys like it!

Thank you!
