Super useful for machining

I use this app for turning and milling. It’s great for computing speeds and also for referencing items. Aside from calculations there is a lot of information contained in this app if you know where to look for it. Wish it had Involute gear and rotating table calculations maybe in some future release. Definitely worth the price, great to have all this specialized information in your pocket for those times you are at the machining table and don’t feel like pulling out the big books!

Button presses are abysmal

There are quite a few good utilities here though the UI has one major flaw and several areas that need improvement. The major flaw is that it takes multiple presses on the buttons for data entry. A friend recommended the app to me but warned me of this problem. I didn’t realize how serious it was. Also in some case the button location is not correct so one has to press slightly above (or below) the location of the button to get the correct entry. Really, THIS NEEDS TO GET FIXED!! This app is not worth the money until this problem is resolved! No other app I have ever used has a basic data entry problem like this, please fix it. The app would get four stars if this problem was fixed. I tend not to use it because of this. The other problems are order-of-event issues with the UI, but they pale in comparison the the button entry issue.

Developer Response ,

Hello ojoazul - Please try the newest version of the app. It was released 11/08/18. This should fix your issue. Email me at shanesuan2@gmail.com if you have any problems.

Great App

I’ve used this app daily since I purchased it. It has worked flawlessly. All the issues mentioned in older reviews have been corrected. The developer seems to one of the rare ones that actually cares about his product. I would like to see the addition of a drill point length calculator. Just a simple version where you can enter drill diameter and point angle, and it will give you the point length. If you are a machinist or manufacturing engineer this is a handy app.

Developer Response ,

Thank you Rod. The drill point length calculator can be found in the "DRILL CALC" section. Just scroll down 👍
