To all shiftworkers out there, what app(s) do you use to manage your shifts/rosters? I'm looking for one that will sync between my iPhone and iPad. So far the only one that I can find that will do this is "Firehouse Scheduler". It's OK but flaky in the sync'ing department. Also, the app that I'm looking for needs to be able to manage stats such as hours worked, overtime, annual leave and so on. Again, Firehouse does have these functions but, again, it's a bit flaky.
