About

Eventor Play

Features
Read full description

Eventor Play records your attendance at classes and events. You walk into the room with the app open and it recognises the venue's beacon, or you scan the code the organiser shows. You see at once whether the registration was accepted, and for each of your groups how many events you have attended and how many are left to the required minimum. If you run events, the same app shows you the day: what is running now, how many registrations are going through, and which ones look doubtful and need a decision. Event settings are changed from here. Eventor Play needs an organisation that uses the Eventor platform. Ask your institution's administrator for access. Bluetooth is used only to tell that you are in the room, and your location is not recorded. Your data stays within your organisation.
