Self-tracking, for anything
Discover the connections you hadn't seen yourself.
You track what's relevant to you — no fixed categories. We automatically find the relationships, including ones that only become visible after a few days.
Pattroo is currently invite-only while we test with a small group.
How it works
Three steps, in order — each one feeds the next.
Track what matters to you
Add your own variables, in your own units — no fixed list.
We find the relationships
Automatically, including relationships that only show up a few days later.
You discover the pattern
Insights you'd never have spotted yourself, laid out clearly.
Five kinds of patterns
Not just "does this correlate" — five distinct kinds of relationships, each suited to a different question.
Two variables that move together — higher caffeine, higher energy — with or without a delay.
A variable that's gradually rising or falling over time, regardless of anything else.
A variable that behaves differently on a specific day of the week — consistently low energy on Mondays.
A real shift around a point in time. Flagged as exploratory on purpose — never overstated.
A run of days that tends to be followed by a change in something else right after.
Built to be honest, not impressive
Patterns are easy to fake with a big, confident-looking number. Pattroo is built the other way around.
Real statistics, nothing invented
Every pattern comes from an established statistical method — the same kind used in research — not a made-up score.
Plain strength labels
Weak, Moderate, Fairly strong, Strong — the same four words everywhere. The exact number is always one click away for anyone who wants it.
Correlation isn't causation
Pattroo shows you what's worth paying attention to — never a diagnosis, and never medical advice.
Complete freedom
No fixed list of categories. You decide what you track, and in what unit.
Time-lagged relationships
Not just “does this correlate”, but also “does this show up a few days later”.
One overview
All your relationships fully visible at any time — no weekly drip-feed, no clinical list.
