corr(work, life)

See what moves together.

corr connects the sources you already have — Health, Calendar, GitHub, Oura — and finds the patterns between them. Then it tells you, in a sentence, with the number behind it. Nothing to log. Ever.

Correlation, not causation. We show you the pattern and don't pretend to know why.

What it finds

pairrwhat corr says
corr(sleep_hours, commits)0.61// your best days follow 7h+
corr(meeting_hours, steps)-0.54// back-to-back days, you stop moving
corr(prs_after_10pm, hrv_next_day)-0.47// late PRs cost you tomorrow
corr(weekend_offline, monday_focus)0.58// the weekends you log off, Monday ships
corr(coffee_after_2pm, deep_sleep)-0.39// you already suspected this

Example findings. Yours come from your own sources, need a few weeks of data, and arrive in the chat as plain sentences — the number is there if you want it.

How it works

1 / connect

Tap the sources you use.

Sign in once. corr only ever reads. Apple Health is read on your phone and never leaves it.

2 / wait

Do nothing.

It watches for a couple of weeks. There is no form, no daily check-in, no number to type. If you have to log something, we built it wrong.

3 / read

Ask it anything.

Findings arrive as sentences in one chat, and you can ask why, what to change, or what happened last month. It answers from your data, not a pep-talk script.

Dashed ones are on the way. A source with an MCP server connects itself — no waiting on us.

Where we draw the line

Reads only.

corr never writes to your accounts. Every connection asks for the smallest read scope the provider offers.

Health stays on the phone.

Apple Health is read by the app on the device. The server never sees a HealthKit sample.

No manual logging.

Numbers arrive only through connections. There is no "add entry" button anywhere, and there won't be.

Your life has patterns. You're just not the one who gets to see them.
