Study time is almost always self-reported, and self-report is exactly where the honesty goes. Rawen's own framing of the problem is blunt: you will say you studied three hours; the band shows the real number.
The design constraint follows from that. A device meant to correct a distraction problem cannot itself be a distraction, so Rawen has no screen, no microphone, no camera and no GPS — one button, and sensors for motion, light and heart rate. It stores several days of sessions offline and syncs over Bluetooth once a day, which is also why a single charge lasts about a week.
The product is deliberately positioned as a mirror rather than a monitor: the daily summary is for the student, not for anyone watching them.
