TimeTree - Free Shared Calendar

The mobile solution enables you to create multiple calendars and use them to keep track of personal, family or work events. Furthermore, after designing a timetable, you can invite the right people to join the group, and coordinate joint activities together.
Recording a new happening on the agenda is remarkably straightforward.  Pick the date, enter a title, select a color, indicate location, attach additional links or notes, turn on notifications, point out the time interval and specify whether it recurs daily, weekly or yearly.
All group members can include and edit special occasions in a shared calendar, not only the admin. More than that, on the event page, users can send pictures, write comments and chat, just like with any messaging app.
TimeTree also helps you see on the same schedule all daily, weekly and monthly events, without having to switch from a calendar to another. Set reminders to make sure you do not forget about any family celebration, birthday party or business meeting.
