About
If your migraines follow your period, Baro shows you — in your own data, not a theory.
Log an attack in seconds on a dark screen, with huge buttons and no typing. No account, ever. Nothing leaves your phone.
YOUR ATTACKS, ON YOUR CYCLE
Log your period by tapping days on the calendar, or import it from Apple Health so you are not entering it twice. Baro places every attack against your cycle and gives you the line a neurologist actually asks for: "4 of 5 attacks on cycle days -2 to +3."
BUILT FOR THE WORST HOUR
Hold one button to start logging. Pain, triggers, medications and where it hurts are all optional and all one tap. Had to stop halfway? The attack stays open and waits for you.
YOUR DOCTOR'S PLAN, ON A TIMER
Put your own protocol in once — water, a pain reliever, a rescue step — and Baro reminds you when each step is due, then records what you took and when. The plan is yours. Baro never suggests a medication or a dose.
THE PRESSURE STORY, ATTACHED
Baro records the barometric run-up to every attack, so you can find out whether weather is really one of your triggers instead of wondering. Readings in both inHg and hPa.
ONE PAGE FOR YOUR NEUROLOGIST
Attacks, attack days, average pain, medication days with an overuse flag, and your cycle-linked count. The summary a three-month diary gets asked for, in one tap.
FREE FOREVER
The log, your full history, the per-attack pressure receipt and the doctor PDF are free forever. No ads, no data sales. Everything stays on your phone.
BARO PRO
- Patterns across every attack: pressure windows, sleep, meals and cycle, each line cited from your own history.
- The advanced report: a six-month trend and a pressure-correlation page.
Baro Pro is 14.99 a year with a 7-day free trial, or 39.99 once. A year, not a month.
Baro is a diary. It does not diagnose, treat or prevent any condition. Always follow your own clinician's advice.

What's New in Migraine & Cycle Tracker
1.0.1
August 9, 2026
You can now log your period the moment you install Baro — the calendar is there from the first launch, and it always tells you what it can and cannot see yet about your cycle. Also: the attack plan waits for its timer instead of letting you skip ahead, the pressure story can be added to an attack you have already logged, your local pressure follows you when you travel, and the doctor report no longer calls a number "relief" when it is really the time from your first medication to the attack ending.
