Your calendar
has a recovery cost.

DayGauge reads your calendar shape and Apple Watch recovery data, then sends three calendar decisions every Sunday. Built for meeting-heavy PMs and EMs.

No event titles, attendees, or addresses are ever read or stored. Calendar shape only.

Calendar shape, not content.

We read meeting count, duration, and gaps. Never titles or attendees. Apple's most restricted Calendar scope.

Three decisions, not a dashboard.

Every Sunday at 7pm, the Brief lands with three concrete calendar edits for next week. Move the late meeting. Protect the recovery block. Stop reading rings.

Cited, not generic.

Every recommendation links to the research behind it. Clow 2010, Åkerstedt 2020, Mark 2008. No wellness platitudes.

Who it's for

DayGauge is built for one person: a meeting-heavy product or engineering manager, in a London or NYC tech company, who wears an Apple Watch and already complains about calendar debt.

Also useful if your calendar shape drives your energy, sleep, or recovery.

If neither of those is you, this probably isn't the app you're looking for.
