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.
