Private · local-first · for iPhone
A calm, private journal for migraine, reflux, sleep, food and the weather around you — tracked together, so you can see how they line up over time.
Try it
Living with a condition is effort enough — the diary shouldn't be. This is the real flow, right in your browser. Go on, log one.
Tap one — the timer starts when you do.
Severity is always labelled — never colour alone.
That's the whole thing. No forms, no login, no loading spinner.
In the app, the weather, barometric pressure and last night's sleep are captured automatically — so most days, this is all the effort a good diary takes.
Cross-condition view
Most trackers follow one thing in isolation. Patternwise holds your conditions side by side on the same timeline — so when one tends to show up before another, you can see it in your own history.
Illustration with example data. Patternwise shows you what you logged in the days around an entry — context to explore with your doctor, never a cause, a diagnosis, or a prediction.
Why Patternwise
Made by one developer for his wife's migraines and reflux — then shaped by what actually survives months of daily use.
Migraine, reflux and any condition you define live side by side — so cross-connections can surface instead of hiding in separate apps.
Pick what and how intense — done. Food, sleep, stress and custom factors take a tap. You just tried it above.
Entries are stored encrypted on your device and never uploaded. No account. Optional AI summaries run entirely on-device.
A calendar and frequency view, plus a look-back at what you logged around an entry — context, never a verdict. No predictions.
Keep separate private profiles for more than one person on the same phone — each with their own conditions and history.
Export a clean CSV or a tidy PDF summary any time — to keep, or to bring to your doctor.
A calm place for hard days
The sage-green palette isn't a style choice alone — green is the light a migraine brain tolerates best, and the whole app avoids the harsh blues and whites that make bad days worse.



Privacy
Patternwise has no backend, no account and no analytics SDKs — we couldn't read your journal if we wanted to. That's not a settings toggle; it's the architecture.

The diary itself — logging, history, export — is free and always will be. Premium exists so one purchase can keep the app independent, private and ad-free.
