About time...

App seems to run good. Just needs some upgrades so that it actually adds up truck$, dump $,night diff, Ect. So when you click save payroll it actually gives you Accurate numbers

Minor adjustment is needed

When starting at 0400 it still shows the moon icon when it isn’t a nigh differential shift.

Thought it was Schemer App

This is nice and hopefully in development still. It’s basically a pen and paper calendar for now. It doesn’t tally any accumulative stats (truck money, charts made etc..) This replaces writing down what you did for the day at best. That’s pretty much it. Glad we finally have something for iOS, and hope this develops more.
