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.

Updated review: Still a superb app I use it in work everyday! Asked the dev to include BSP threads. And he has updated it with BSBPP. One of the best features on thread data is the ability to switch from inch and metric for the data! There are alot of very helpful features in the app which I use daily. I still think the app could use some tweaks to make it slightly easier to navigate and a few more features added. But with a dev who actively listens/replies to suggestions. 5 stars from me!
