iAttended

Confirm your attendance at events and meetings by simply scanning a QR code, entering a text code, watching a video, or, in some cases, clicking a button to say you're there. You'll get immediate confirmation that your presence was recorded, and you'll be able to track your progress towards meeting attendance requirements defined by a school or organization.
Login is as easy as entering your email, though you can also use existing logins from Apple, Google, or Microsoft. Once logged in, your attendance data is stored in the cloud and syncs immediately with the school or organization that hosted the event, meaning you can know that they know you were there.
