Machinist Sidekick is a tool for machinist and engineers to handle a lot of the tedious day to day calculations in the shop. The user interface has been completely overhauled and is now greatly organized. The Full version includes much more functionality. Machinist have seemed to love this app thus far. It has real application to the job. The newest and best version of the app has been released. Version 15 (4.0) has been a great success. With the inclusion of swiping, tabs, references, and many more functions. The Full version is still most definitely the way too go. Thanks to all the machinist guys and gals that have given feedback on the app, it is greatly appreciated. Note: Version 15 is only available to platform 3.0 (API 11 and above) and above given the nature of the apps navigation. Thanks, Tom.
