Orgo

Orgo is your go-to app for keeping everyone in your group in sync with all of theirs and everyone else's activities and appointments every day. All members can easily access Orgo from their phones to use its shared organizer, reminders, to-dos for shared tasks lists, and a journal or notes keeper. Recognizing that everyone has different circles of people they schedule activities for, Orgo allows you to create and manage multiple groups.
Orgo's intuitive interface makes it easy to use. It is free and available for iOS and Android phones.
