Ratings and reviews

Love this app. It literally has every feature you could ever use. Amazing how extensive it is. You could use 10 different apps and not have as much as this gem. No issues of animations or slow scrolling as another review mentioned. Easily switch between metric or imperial. Custom macros, thermal expansion, angles, weight, everything! Great developer, well worth the cost and I highly recommend this invaluable tool!

A nice app with a lot of great tools baked in. However one thing that bothers me are the animations. For example, the drill and tap chart. It takes what seems forever to scroll down because of the smooth animation. Or the G and M codes list. It takes way, way, way too long to scroll down the list. Granted I don't use G or M codes feature but that is one area that could a major improvement.

As of now, I'm still a greenhorn when it comes to machining. So my knowledge of how to set tools at the right speeds is lack luxture, but this app has been a great help in learning as well as not breaking tooling with incorrect speeds and feeds. I also use to find the correct drill sizes for taps which is always a bit difficult without a proper chart.

What's new

Easily convert inch thread data to metric & metric data to inch in the "Thread Data" section
Also flattened some bugs
