Find what changes how you feel.
Logging your day takes a few seconds of tapping. Patterns finds what actually makes a difference to your symptoms, sleep, mood and energy.

Stop guessing.
Know what really sets off your symptoms, based on your own days instead of the internet's lists. Patterns ranks what seems to matter most, strongest first, so you know which changes are worth making.

Patterns you'd never catch yourself.
Some effects take days to show up. Some build up over weeks. Some only happen when two things come together. Patterns looks at all of your days at once, and only speaks up when your own data backs it up.
- Catches effects that show up days or weeks later, or build up over time
- Finds triggers that only matter together, like alcohol on a night of poor sleep
- Learns your cycle: what shows up before your period, and what makes it late
- Gives you a heads-up when something that usually leads to a symptom just happened
- Rules out flukes, and tells you how sure it is
- Tells you what it's still checking, and how many more days it needs

Watch your year fill with color.
Every day you log becomes a ring of color. Week by week, you can see the attention you're paying to yourself add up.
- See how often any habit or symptom happened
- A recap at the end of every month
- Streaks, with reminders that skip days you've logged
