Two experiences. One relationship.Each partner sees only what is useful to them.
Why Lights On exists
Care is easier when you know what helps.
Most partners want to be supportive. But cycle awareness rarely becomes something practical. One person still has to explain, remind and ask. The other is left trying to read the room.
Lights On bridges that gap with small, specific guidance shaped around the relationship.
“I want to support you. I just don’t always know what would actually help.”
How it works
Less explaining. Less guessing. More feeling understood.
Set it up together, then let Lights On quietly support the relationship in the background.
