Future updates will include Video Training Sessions. Focusing on a User-Friendly Layout, the Journeyman will continue to grow as more areas are developed and will be released as FREE Updates. Besides just producing the numbers you desire, the Journeyman illustrates certain theories while trying to educate users not familiar with these concepts. This training concept will be continued as the app grows. Visit www.smartcalculations.com to see more. NOTE: We suggest to periodically turn your device off and let it clear any stranded memory. The app will load every time after doing this small step.

User Reviews
Every thing is available that you should need for reference needs as a machinist to a point only thing it doesn’t have that I have to go elsewhere for is metric thread information.
I’ve been using this app since the creation of it. I use it everyday and show it to all my customers. I’ve been selling carbide since 1988 and have covered the Bay Area and Central Valley in California for Mitsubishi Carbide cutting tools for the past 17-1/2 years. It’s very simple and user friendly. Years ago I used an app on my old palm pilot called “Machinist”. I wish these 2 would get together and create one together. “Machinist” was amazing and had a materials data base and would allow you to input the machine data such as rapids, horse power, etc.. so when calculating drilling cycle times it would allow input for distance between the holes. Keep up the great work and thanks for the app!!
I really like the app and use it often. It would be really nice if you could add cycle times to the drilling section. All sections
Using new IOS 10. When right triangle solver is used to calculate. It will take the first known with a decimal point. However when you put the second number in with a decimal it closes the app???
Needs update crashes when adding decimal places to more than one place otherwise it works great
I am an application rep for a company that sells round tools and indexable. Works perfect!
Good app but for $10 they should also include the metric calculations.
They have fixed the issues from the last update. I will happily recommend this app to anyone.
Love this app! You should add a thread turning calculator for all threads (acme, round, exc) with min/max/pitch dia ref, internal and external. Also a ball mill scalop height calculator would be awesome. Great app!!!
Why should I have to go through up front advertisement on an ap that I paid for?! Not smart!
