Passel, sync group events

Passel is not a calendar app but a hub for groups to share out their schedule regardless of the operating system members use. Passel is a free and easy way for groups and teams to communicate with members. Parents simply "follow" a team/group calendar and all events are automatically synced with their native phone calendar. If a date or time is modified followers are notified and iCal is changed automatically.
Additional Features:
*RSVP "Going" or "Not Going" to events
*Admins can push text messages to Followers
*Group "comment board" on events (when enabled by calendar admin) for team/group communication
*Ability to add multiple Admins
*Followers can self organize carpools within each event
*Linked to Google maps for event address
*Followers can leave at any time and team organizers do not have to keep an email group or group-text current
