Shiftwheel is built for rotating shifts: DuPont, Pitman, 4-on-4-off, 2-2-4, or a pattern of your own. Set the rotation once and the app projects it forward, onto a month calendar, an agenda, your home and lock screens, and iCal. It tracks pay-period hours and overtime and counts down to payday. The schedule core works offline with no account, pay settings never leave the phone, and the optional assistant can answer schedule questions or read a posted roster from a photo. Built by a mill worker on a 50-day rotation.
