Everyone searching for the best migraine tracker apps is really asking one of three different questions. Some need a diary a neurologist asked them to keep. Some want to find out, properly, whether wine or sleep or weather is doing this to them. And some just need to record that an attack happened, right now, in a dark room, with one hand. Those are not the same product, and picking the wrong one is why most migraine logs die in week two.
So this list is organised by job, not by ranking. One of these is ours — MigrainePal — and we've put it on the single job it genuinely wins, and named other apps for the jobs they win. Every app here is real, on iOS, and free to download.
Best for logging an attack while it's happening: MigrainePal
Every other app on this list is built around the assumption that you can answer questions. MigrainePal is built around the moment you can't. When an attack starts you tap once, the app opens an active episode stamped with the start time, and you put the phone face-down. Pain level, aura, triggers and medication get added later, when your head clears — which is the only realistic time to add them.
That one decision shapes the rest of it. The headache calendar shows a whole month visually rather than as a wall of text, so cluster days, weather-linked spikes and menstrual patterns surface by shape. Trigger tracking is opportunistic — log sleep, stress, food, weather, screens, hormones or scents when you notice them, rather than filling a checklist. The medication log covers triptans, NSAIDs, anti-CGRP and preventives, and is honest about helping you notice when you're drifting toward medication overuse territory. Insights read in plain language — frequency, average pain level, aura percentage, most common triggers, medication response — so you can hand your neurologist the phone rather than an export.
It's a native iOS app with Dark Mode and Dynamic Type, which matters more than it sounds when you're looking at a screen with a pounding head. No account, no data collection, no ads; records stay on-device with optional Apple-encrypted iCloud sync. Free, in English, Japanese and Traditional Chinese.
Skip it if your clinician has asked for formal structured exports, or you want an algorithm to do statistical trigger analysis for you.
Best for doctor-ready reports: Migraine Buddy
Migraine Buddy is the giant of this category and deserves the position. It's made by Aptar Digital Health, claims around four million community members, and holds a 4.8 rating from over 250,000 ratings — a scale no other app here approaches. It was started by someone who lives with migraine and built with neurologist input, and it shows in what it prioritises: structured logging of symptoms, triggers, medications and migraine-free days, pattern and trigger-correlation analytics, medication reminders, and shareable reports designed for healthcare providers.
That report is the real product. If your neurologist wants documentation — or you need to make a case to an employer or an insurer — this is the app whose output was designed for exactly that. It's free with a premium tier called MBplus.
Skip it if the structured questionnaire is the thing standing between you and actually logging an attack. We wrote a longer, fairer MigrainePal vs Migraine Buddy comparison if you're weighing exactly these two.
Best for scientific trigger analysis: N1-Headache
N1-Headache, from Curelator, is the most rigorous tool here. Its stated purpose is to let you "scientifically discover everyday factors that can increase, decrease or have no association with your risk of migraine" — note the middle and last clauses, which are the ones most trigger tracking quietly ignores. Ruling a suspected trigger out is as valuable as confirming one, and few apps will tell you that chocolate isn't doing anything.
It pairs a mobile app with a web dashboard on the clinician side, so a provider can follow your data between appointments, and the company publishes peer-reviewed research with clinical advisory boards. Pricing isn't listed publicly, but clinicians can hand out a Clinician Code that gives patients free premium access — worth asking about at your next appointment.
Skip it if you're not prepared to log consistently. Statistical analysis needs volume; sporadic entries produce nothing.
Best when migraine is one of several conditions: Bearable
Bearable isn't a migraine app — it's a general symptom and mood tracker founded by someone with chronic migraines, and that's precisely why it belongs here. If your migraines sit alongside a mental-health condition, another chronic illness, or a treatment whose side effects you're trying to separate from your headaches, a migraine-only diary can't see the interaction.
It tracks custom symptoms, mood, medications and treatments, sleep, energy, nutrition and hydration, menstrual cycle, activity, and measurements like heart rate and blood pressure, then runs 30+ reports over the lot — correlations, weekly and monthly trends, and structured experiments to test whether a change actually helped. It syncs with Apple Health, Google Fit and Fitbit, so some of that arrives without typing. Free tier includes unlimited custom symptom tracking, weekly reports and basic correlation graphs; premium unlocks the deeper correlation reports and longer history. Rated 4.7 on iOS.
Skip it if migraine is the only thing you're tracking — the breadth becomes overhead.
Best for staying connected to a specialist: Migraine Monitor
Migraine Monitor, from RPM Healthcare, is built around the patient-to-specialist link rather than around self-analysis. You log symptoms, and the point of the logging is that your specialist can see it — the app is explicitly positioned to "connect patients with their specialists" for coordinated care. It won a Digital Health Award in 2018.
It's the narrowest pick here, and worth it mainly if your headache clinic already works with it or you want your tracking tied directly into care rather than sitting in your own phone.
Skip it if you're tracking independently — the value is in the connection, and without it there's less on offer than the alternatives above.
Which one for which job
| If you need to… | Use | Because |
|---|---|---|
| Log during an attack | MigrainePal | One tap opens the episode; details backfilled later |
| Give your doctor a report | Migraine Buddy | Provider-shareable reports, built with neurologist input |
| Prove or rule out a trigger | N1-Headache | Statistical risk-factor analysis, clinician dashboard |
| Track migraine plus other conditions | Bearable | 30+ reports across symptoms, mood, meds and sleep |
| Stay linked to a specialist | Migraine Monitor | Built around patient-to-provider connection |
| Track with no account at all | MigrainePal | On-device records, optional encrypted iCloud sync |
The honest summary
The best migraine tracker app is the one you'll still be using in March. That sounds like a platitude until you look at what actually kills migraine logs: not a missing feature, but a mismatch between how much the app asks for and how much you can give at the moment it asks. Research-grade tools ask a lot because the analysis genuinely needs it, and if you can sustain that, the payoff is real. If you can't — if the honest truth is that during an attack you can barely look at the screen — then the app that captures a single timestamp beats the app that captures twenty fields you never enter.
Be honest about which of those you are. Then pick from this list and stop shopping, because three months of mediocre data beats another week of comparing apps.
Frequently asked questions
What is the best free migraine tracker app?
All five apps on this list are free to download, and each keeps some capability behind a paid tier. MigrainePal is free with an optional upgrade and needs no account at all. Migraine Buddy is free with an MBplus premium tier. Bearable has a genuinely usable free tier including unlimited custom symptom tracking and weekly reports. Which is best free depends on whether you want speed during an attack, reports for a doctor, or correlation analysis across many symptoms.
Which migraine app is best for showing my neurologist?
Migraine Buddy is the strongest choice if your clinician wants structured documentation — it was built with neurologist input and generates shareable reports for healthcare providers. N1-Headache is designed to be used alongside a clinician too, with a web dashboard on the provider side. MigrainePal takes a lighter approach: its Insights screen shows frequency, average pain level, aura percentage and medication response in plain language you can hand over on the phone, without exporting a PDF.
Do I need to log every trigger to find my migraine patterns?
No, and trying to is the most common reason people abandon migraine tracking. Consistency beats completeness — a log that captures the date, rough pain level and any medication for every attack is far more useful after three months than a perfectly detailed log you kept for nine days. Add trigger notes when you happen to notice something, not as a checklist you owe the app.
Can I track migraines without creating an account?
Yes. MigrainePal requires no account and keeps attack records, trigger notes and medication history on your device, with optional iCloud sync between your own devices encrypted by Apple. Most research-oriented migraine apps do require an account, because syncing your data to their servers is how the analysis and the provider reporting work.
A migraine diary you can use mid-attack
One tap starts the episode. Pain level, aura and meds go in later, when you can. No account, no data collection.
