On iPhone, web notifications only work from the Home Screen app. Tap Share → Add to Home Screen, open it from there, then turn this on. Or use the calendar subscription below, which works everywhere.

Desk time, headcounts and breaks never trigger a notification.

The feed keeps itself up to date and sets a 15-minute alert on every non-desk block — this is the option that works on any phone, no app install needed. In Google Calendar use Other calendars → From URL.

Opens straight to your name — handy to send to a coworker.
