Two hours outside a week is linked to feeling better. We’ll find you the hours.

You already know a day outside does you good. The hard part is not the knowing; it is the grey Tuesday when going out feels like one more decision. Perfect Day makes the decision once, in advance: you say what a good day is for you, it watches the forecast for the places you go, and when one is coming it sends one message: Thursday looks like the good one. 3 pm to 7 pm, 66–73°, bright. No streaks, no badges, no notification about weather you did not ask about.

What the research says, and what it doesn’t

A 2019 study of nearly twenty thousand people in England found that those who spent at least 120 minutes a week in nature were more likely to report good health and high wellbeing than those who spent none. That is an association, not a prescription, and Perfect Day is not a treatment for anything. It is a way of noticing the good afternoon before it is over, which for most people is the whole difficulty.

How it works

Describe a good day once: a temperature range, how humid is too humid, how much rain chance you will accept, how much wind, and how many good hours in a row you need. Add the places. Perfect Day fetches five weather models every three hours, averages them hour by hour, and judges the next ten days against your rule. When a day qualifies, everyone on the account gets one plain message. When the forecast turns, one more. Otherwise, nothing — which is most weeks.
