How we help
Turn daily logging into an answer you can trust
Ask your own questions
Build a study around whatever you're curious about — sleep, diet, mood, work habits — with simple daily yes/no or 1–10 questions. A minute a day, most days.
Real statistics, not vibes
Effect sizes, significance testing corrected for multiple comparisons, and a minimum-data threshold before anything gets called a "link" at all.
Catches delayed effects
Some effects show up the same day; others take a day or three. We test a full lag sweep and show you the pattern, not just one number.
Start from a template
Dozens of ready-made study templates — health and everyday habits alike — so you're not staring at a blank page deciding what to ask yourself.
Share safely with your doctor
Export a clean PDF of one study's results — no account needed to view it, share it however you'd like.
Ask your data questions
Optionally connect Claude or another MCP-compatible AI assistant to ask about your own logged data conversationally, study by study, entirely opt-in.
How it works
Two steps, most days a minute or less
Create a study and start logging
Pick a template or write your own cause and result questions, then log a quick daily check-in — a reminder email brings you straight into today's questions, no app, no login friction.
See what actually correlates
Once there's enough data, we surface which causes line up with which results — and how strongly.
