As answered by people managing Code Effects and Attenda.
Attenda's answer:
Attenda keeps everything on the phone. There are no student logins, no accounts, no cloud sync, and no tracking — the roster never leaves your device. Taking attendance is a swipe: right for present, left for absent, so a whole class or team is done in seconds. It is built for the actual moment of taking attendance, not for administration, which is why nobody resists using it.
Attenda's answer:
Most attendance apps push you toward accounts, cloud sync, and student logins, and treat attendance as one feature buried inside a larger platform. Attenda does the opposite. Your roster stays on your phone, nobody else has to install or log into anything, and there is no data to manage or leak. It does one thing — take attendance for a class, team, or club — and does it fast and privately, so it stays out of your way.
Attenda's answer:
Teachers, coaches, and anyone who runs a recurring group — small classes, tutoring, clubs, youth sports, and church or community groups. In short, anyone who takes attendance for the same set of people on a regular basis and wants it to be quick, private, and free of accounts or student logins.
Attenda's answer:
Attenda is made by AnchorKite, an independent software company that builds small, considered apps. It started from a simple frustration: taking attendance should take seconds, and it should not require accounts, student logins, or handing a roster to a cloud service. Most tools do the opposite. So Attenda was built to do that one job — fast, on-device, and private — and nothing more.
