Work Scheduling app

[Oridus]

I was wondering if there was an app out there that would help me produce work schedules for my staff. The way we do them on the computer at work, is a week view (Tuesday through monday)... and we can either pick a day - and do line scheduling (Showing the break down of which hours each person would work on that given day with something that resembles a line graph), or we have our week view and have it show each person on our staff and which hours they're scheduled on any given day.

This would help while im out on the road, instead of pen/paper (i have HORRIBLE hand writing). That way when i get back to the office, I can just look at my phone and duplicate the work schedule without having to worry of deciphering if it was a B or an 8.

Thanks in advance.
