How to get started

Three steps.
Then you're in.

01
Choose migraine or allergy mode
Pick the flow that matches what you're tracking — or use both over time.
02
Log episodes and triggers
Capture severity, timing, and likely triggers while details are still fresh.
03
Export for your doctor
Generate a clean PDF summary when you need something clinic-ready — no account required.

Features

Everything that matters.
Nothing that doesn’t.

Migraine and allergy modes in one app
Trigger logging, history, and insights
Charts for frequency, severity, and correlations
Doctor-ready PDF export — no account, no server

Partnerships

Built with the platforms you already use.

01

On-device privacy

Logs and exports never need an account or server.

Doctor-ready summaries you can share from the Files app.

03

Health workflows

Built to sit beside clinic visits, not replace them.

Trace is still an experiment.
