The Best Migraine Tracking App Is the One You Still Use

I make one of the apps in this category, so read this the way you would read any review written by someone with a stake in the answer. What follows names competitors, says where they are better, and ends without telling you which to install. If that is not what you wanted from a page with this title, the honest summary is at the bottom of this paragraph: the best migraine tracking app is whichever one you are still filling in twelve weeks from now, and almost nothing else about the choice matters.

That sounds like a dodge. It is actually the whole finding, and the reason is arithmetic.

Why month three decides it

Every threshold in headache medicine is counted in days per month. Whether a pattern meets a definition, whether a preventive did anything, whether acute medication use has crossed a line — all of it is a rate, and a rate needs a denominator.

A diary with three weeks missing cannot produce one. It can prove that bad days happened, which you already knew. So an app that captures twelve fields beautifully for five weeks and then gets skipped loses to a notes app used every day, and it loses badly rather than narrowly.

Which turns the choice into a question about failure modes rather than features. Four of them decide it.

1. How long does logging take at severity eight?

Not on the demo screen. During an attack, one-handed, in the dark, with the brightness at zero.

This is the one thing worth testing before you commit, and you can test it inside a week. Install a candidate, wait for a real attack, and see whether you actually opened it. An app that requires you to pick a pain location on a diagram, tick six symptoms and rate three sliders is asking for a minute you may not have, and the field it loses first is the start time — which happens to be the one a clinician can most use.

The design decision underneath every app in this category is where it sits on that trade. More fields captured per attack, or more attacks captured. There is no version that gets both.

2. Does it produce the four numbers?

Migraine days per month. Total headache days per month. Acute medication days per month. A disability score.

Those are what a headache appointment is largely spent establishing, and they are the output that matters. Plenty of trackers record beautifully and then show you a wall of entries, leaving the counting to you — which is the specific job you wanted a computer for.

Two details separate the ones that count properly. Days rather than attacks: an attack running from Tuesday evening into Wednesday afternoon is two migraine days, and an app that reports “1 attack” is giving you a number the criteria are not written in. And medication days rather than doses: three doses on one day is one medication day, counted the same way the diagnostic thresholds count it. Medication overuse headache: how many days is too many covers why that distinction changes the answer.

3. What happens to the data if you stop paying, or stop using it?

Ask before you start, because the answer is hard to change afterwards.

Can you export everything, in a format that is still readable without the app? Does the record live on a server, and if so, whose? For a health diary this is not an abstract concern — you are about to build a two-year record of a neurological condition, and where it sits is a decision you make once, silently, on day one.

The paired question is which half of the app is free. In migraine trackers “free” almost always means free to log and paid to understand, and how to tell which free you are getting is a check you can run off the App Store page before you build any history at all.

4. Can it record the one thing paper cannot?

Barometric pressure over the preceding 24 hours, stamped at the moment you log.

It is the only field a later lookup cannot reliably fill in for you: an hourly archive can answer only for the time and place you give it, and an entry that says “Tuesday” gives it neither. Everything else you can write up that evening. Weather noted the following day from what you remember of the sky measures your beliefs about weather, which is worse than not recording it, because it looks like data. If you suspect weather plays a part for you, this is the one capability worth choosing an app over paper for — and why the pressure studies disagree is worth reading first, because the effect the research supports is on how often attacks come rather than how bad they are. The implementation detail that decides whether the field is worth anything is when the app takes the reading: a value stamped as you log and a value looked up afterwards are not the same measurement.

Where the other apps are better

First the part you can check without me. Everything below is read off the App Store listings as of August 2026, so it is verifiable and it will go stale — dates and platforms move, and the listing is the authority, not this page.

Question one is deliberately absent from it. How long logging takes at severity eight is the question that decides the whole thing, and there is no honest column for it: I cannot time someone else’s app during someone else’s attack, and a number I invented for a competitor would be worth less than no table at all.

	Platform	Pressure or weather	Export for an appointment	Last updated
Migraine Journal	iPhone, iOS 17+	Yes, stamped when you log	PDF summary	August 2026
Migraine Buddy	iPhone and Android	Yes, 7-day forecast	“Comprehensive reports”	May 2026
N1-Headache	iPhone, iOS 11+	Yes	PDF analytical report	January 2023
Apple Health	Pre-installed on iPhone	No	No	Ships with iOS
Paper	Anything	No, and cannot be added later	It is already paper	—

Migraine Buddy, listed on the App Store under Voluntis, is the largest by a distance and uses the phone’s own sensors to pick up movement and sleep alongside what you type. If you want sleep captured without having to remember to enter it, that is a real advantage and my app does not have it. The scale brings a second benefit that has nothing to do with software: a very large user base, and the sense of a place where this condition is ordinary.

N1-Headache, from Curelator, is doing something genuinely different. After 90 days of tracking it produces individual trigger and protector maps — a statistical read of which factors associate with your own attacks, including the ones that appear to be protective. If what you want is a serious attempt at per-person trigger analysis rather than a diary that also charts, it is the most ambitious option in the category and it is not close.

One caveat on that recommendation, and it is a serious one: its listing shows version 3.0.2, last updated in January 2023, still targeting iOS 11. Three and a half years without an update does not mean an app has stopped working, and the analysis it already does is unaffected. It does mean nobody should start a multi-year health record in it without first installing it and checking it still runs properly on a current iPhone.

Apple Health is already on the phone and costs nothing, which is not nothing. It will record a headache with a severity and a start and end time, and that is close to the whole of it — no medication tied to the attack, no note of what it stopped you doing, and no monthly count of the kind above. How to log a headache in Apple Health walks the four taps and is honest about the three fields it has nowhere to put.

Paper beats all of it for the first three months. Nothing to learn, no screen to wake, and the friction of a pen is genuinely lower during a bad week. The free printable diary is a monthly grid designed so that filling it in produces the four numbers above.

Migraine Journal, the one I build, is a bet on the first question rather than the second or third: log in under a minute, capture the pressure change automatically, and print the summary. It does less analysis than N1-Headache and has no sensor integration. Whether that trade is the right one depends entirely on whether you are someone who abandons diaries, and you know the answer to that better than I do.

The test that settles it

Pick one. Any of them. Use it for six weeks without switching.

The switching is the actual risk here, more than picking wrong. Four weeks in one app and five in another produces two records that cannot be added together — no migraine app imports another one’s history — and the person who has tried five migraine apps has, in tracking terms, nothing. A mediocre choice held for three months beats the best one in the category restarted three times.

At the end of six weeks, ask whether you logged the bad attacks or only the manageable ones. If the answer is only the manageable ones, the app is too slow for you, whatever its features do on a good day. That is the finding, and it is worth more than every column in the table above put together.

What no app can do is interpret itself, and none of this is medical advice. The record’s real payoff is at the appointment, where the four numbers on one page change the conversation regardless of which icon they came out of.
