Why track your
happiness daily?

It's hard to remember what makes us happy. By Friday, Monday is a blur. A mindful sentence a day, captured in the moment, turns into the most honest record you'll ever have of how you actually feel.

01 · notice
Notice what you'd otherwise forget.

The walk that lifted you. The meeting that drained you. How you felt, and why. Captured in the moment.

02 · patterns
Find your more-happy patterns.

After two weeks: top givers, top drainers, your best day of the week. After a month: real signal.

03 · design
Design more happy into your days.

When you can see what fills the tank, you can put more of it on the calendar.

How it works

Thirty seconds. Every evening.

Designed to take less time than checking your messages, so it fits inside the day you're already living.

01

Set today's light.

A single slider, 1 to 10. The lantern dims or brightens to match. That's it.

02

Tag what made the day.

Pick from your activities or jot a new one. Mark each as a giver or a drainer, plus how it felt and a one-line why.

03

See your more-happy shape.

After two weeks the patterns appear. After a month you know what to keep doing, and what to design out.
