Easy to use. Managing different worksites/shifts is easy. Syncs to my Google calender. Only complaint is the length of time it takes yup sync the data. Update: this has trouble syncing to my Google calender. I reset it and it synced one month but not anymore than that. I don't want to have to go into my Google calender and reset this each time. Once this is fixed, back to 5 stars. Update: 3 years after that review and still no resolution. I'm glad it's free.
