This free app is popular with parents who use it to log and view each family member’s schedule in one place. You can view schedules by week or month, and each family member’s schedule is color-coded so you can quickly see who’s doing what.

With Cozi, you can set up automated emails with schedule details on a weekly or daily basis and set reminders so no one misses important events. The app also includes shopping and to-do list features that allow every family member to contribute so nothing falls through the cracks.
