Greek Chapter is the easiest way to manage your greek organization on campus. — Study Hour Tracking — Our GPS-based study hours system ensures that your members are getting their hours in designated locations created by your organization. We're able to detect when members are using methods to game the system and block these actions so that they receive credit for only what they have actually completed. — Announcements — Your chapter leaders and designated members are able to send important information to users in the app and through push notifications. Announcements will stay prominent in the dashboard until they are deactivated by your leaders. — Gallery — All of your memories in one place for the entire organization — Points Management — Point tracking is often complicated and typically requires a computer to modify a spreadsheet.

Choose from a variety of different polling methods and start collecting answers from your members in no time. Member didn't respond to a poll yet? Nudge them with a push notification to get the poll back on their mind. — Events — It's important to keep the entire chapter updated on when and where certain events are taking place. You can keep track of these on the Greek Chapter calendar and members will receive push notifications alerting them about what they have upcoming. — Guest Lists — Have an upcoming social event that is invite-only? Create guest lists that are easily searchable so that you can quickly verify if someone is on the list or not.
