User Reviews
I use this app for various things, but it’s worth it for the thread data alone. If you’re single pointing a lot of threads, it’s very handy to have thread data at your fingertips.
I would have given this 5 stars a few years ago. It’s a great app and has a lot of useful information, but the creators of it seem to have abandoned it and aren’t adding any more features. Which is a shame cause this is my go to apps for machinist reference.
I use this app every day programming mills and designing fixtures
I bought this app several years ago. I gave them a 5 star review the first time. They ask me every month for another review. Now you get 1 star.
Absolutely love it!!! All the information I need at my fingertips.
Wow.. do I love the brain check portion of this app.. I failed miserably only to memorize the answers and pass all 100%. Would love a new updated version with potentially harder questions and answers.! Love it love it love it. Btw .. recently used the Material weight calculator to ensure that I had enough lifting power for my new 990.2 lbs chunks of 6061 aluminum! Thank you designers and hosts for this app!
I’m a machinist in training still learning and making mistakes, this app helps me a lot with speeds and feed and some of the things I didn’t consider before.
Good
This has everything I need all in one I’ve got 28 years of experience and I e always had to do research for data to have an edge. Now I have all the technical data I could ask for!
No easy reference chart for threads with major and minor diameters etc. you have to go through multiple menus to look up a specific tap or thread size
