One Daily Stream, Calibrated to Her

Every day there is one action. Most days it is the cycle-calibrated Daily action. But the app layers in a few other kinds of guidance when the moment calls for it. You never have to think about which type you're getting. You just open the app and find today's one action.

☀️

Daily

What to do today, tuned to where she is in her cycle. This is the heartbeat of the app; the reason the right action changes every week.

📈

Investment

What to build over time. Longer-horizon actions that invest in the relationship or in yourself; health, provision, household weight, character.

🎯

Milestone

The big recurring dates. Anniversary, her birthday, and similar moments. Prep prompts with lead time, plus day-of guidance so important dates never get fumbled.

📅

Episodic

The occasions in between. Seasonal moments and one-off things coming up; a trip, a holiday, an event. Surfaces while there's still time to act.
