    Anyone in the machining industry should have this app. It has everything needed to answer regular everyday questions on the shop floor. I use it in the QA department and am constantly sharing with my coworkers on the floor.

    I like it when an app works. Good job and very useful. My only complaint is when my Boss sees me at the machine using this app he thinks I'm texting! Thumbs up to an app that makes my job easier. Keep up the good work!
