Best Migraine App: 10 Criteria to Choose the Right One in 2026

By Laurine NicolettiNovember 3, 202612 min

You're lying in a dim room with a pounding head, and the last thing you want is a form with thirty questions. Or your doctor has just asked "how often do you get them?" and you honestly can't say. If you're searching for the best migraine app, the real answer is simple: it's the one you will actually open, even on a bad day.

This guide gives you 10 criteria to compare migraine tracking apps, from how fast you can log an attack to privacy and price. It also says plainly what an app can't do. It's part of our Living with migraine series.

In short

The best migraine app lets you log an attack in seconds and then shows your patterns clearly, so you and your doctor can use them.
Ten criteria matter most: speed, useful fields, triggers, weather, cycle, statistics, a report for your doctor, privacy, price, and a calm design.
A systematic review of 38 headache diary apps found that none met all seven quality criteria the authors set, so it's worth checking an app before you trust it.
An app records and reveals patterns. It doesn't diagnose, treat or cure migraine, and the NHS notes that there is no specific test for it.

What makes the best migraine app?

The best migraine app is the one you can fill in within seconds during an attack and still understand three months later. Everything else is a bonus.

Why does this matter so much? Because a diary only works if it's complete. The Migraine Trust says a diary can help your doctor make a diagnosis, help you spot triggers and warning signs, and show whether your medication is working. It also suggests that keeping one for three months or more will help you and your doctor work out what your triggers might be.

The American Migraine Foundation adds a useful reminder: updating a headache journal shouldn't feel overwhelming. It lists smartphone apps, spreadsheets and paper journals as valid options, so an app is a choice, not an obligation. If paper works for you, keep it. If you'd like something that does the maths and the charts for you, an app can help.

The 10 criteria for choosing a migraine tracking app

You don't need an app that ticks every box. Think of this as a checklist: decide which three or four matter most to you, then compare.

1. Can you log an attack in a few seconds?

Speed of entry is the first test, because you'll often be logging while in pain, nauseous or sensitive to light. Count the taps between opening the app and saving an attack. If you have to scroll through a long questionnaire, you'll skip it on the days it matters most.

A good pattern is a very quick first entry (the attack started, how bad it is), with details you can add later when you feel better. Mellow, for example, lets you record an attack in two taps.

2. Does it record the information that is actually useful?

Look for the basics doctors ask about: when the attack started and ended, how severe it was, where it hurt and what symptoms came with it. The NHS suggests noting the date, time, what you were doing when it began, how long it lasted, your symptoms and any medicines you took.

The 2014 review above judged apps on the clinical relevance of the headache variables they collect. It also found that only 18% of the apps it examined had been created with scientific or clinical headache expertise. That is an older study and the market has moved on, but it's a good reason to check what an app asks and why. Our guide on what to write down in a migraine diary shows what is worth recording.

3. Can you track your own triggers?

A good app lets you note the things that might be playing a role for you: stress, sleep, screens, food, your cycle. The American Migraine Foundation says that over time, patterns may appear that help you and your doctor understand your triggers.

Be wary of apps that hand you a fixed list of "your triggers" after two entries. Triggers are personal and often combine, and it takes weeks of data to see anything. If you'd like to understand how that works, read how to identify your migraine triggers.

4. Does it track the weather or barometric pressure for you?

Automatic weather or pressure tracking saves you from guessing, which is its main value. Many people feel that changes in the weather bring on attacks. The Cleveland Clinic explains that sudden changes in barometric pressure are one of the main weather factors linked to migraine.

Not everyone is sensitive to pressure, and the science is more nuanced than "the weather causes my migraines". That's exactly why an automatic log helps: you can see over time whether your attacks line up with pressure changes, without having to remember to check. Our article on barometric pressure and migraines covers what research says. Mellow records barometric pressure automatically.

5. Can you follow your cycle alongside your attacks?

If you have periods, being able to see attacks next to your cycle is one of the most useful features, because some attacks cluster around menstruation. The NHS also says it can be helpful to note when your period starts, as this can help your doctor identify potential triggers.

Check that cycle tracking is built in rather than something you have to improvise in a notes field. To learn more about this link, see menstrual migraine.

6. Are the statistics clear and calm to read?

Good statistics turn a pile of entries into something you can read at a glance: a calendar, how long attacks last, how intense they are, and how things change over time. Pretty charts aren't enough. You want to be able to answer simple questions such as "how many migraine days did I have last month?"

Be careful about over-reading small numbers. A few entries don't prove anything. Our guide to reading your calendar, duration and intensity explains what to look for and what to ignore.

A report or export you can show or send to your doctor is what turns an app from a personal log into a tool for appointments. The 2014 review listed the ability to export data and to produce reports linking several variables among its ideal criteria.

Your doctor doesn't need every detail. The Migraine Trust makes the same point in its advice on GP appointments: a simple summary is usually enough. If you're not sure who to see, read when to see a doctor for migraine. Mellow includes a report you can bring to your doctor.

8. What happens to your health data?

Check where your data is stored and whether it's shared, because migraine diaries are health data. In a 2018 study in the journal Headache, researchers looked at 14 migraine diary apps. All of them collected medical information, 57% could store diary data on the provider's servers, and 79% had a visible privacy policy.

Among the apps with a visible policy, six of eleven stated that some user data were used to serve targeted advertisements. The authors also noted that there are few legal protections against the sale or disclosure of data from medical apps to third parties. This study is from 2018, so policies will have changed, but the questions it raises are still the right ones:

Does the app say clearly where your data is stored?
Does it share data with advertisers or other companies?
Can you delete your data?
Is the privacy policy easy to find and written in plain language?

9. What does it cost, and what's behind the paywall?

Look at the real price before you invest time in an app, since moving your history later is rarely easy. Some apps are free but run ads or sell data. Others are free for a few weeks and then lock the statistics or the doctor report behind a subscription.

Ask yourself: can I do everything I need without paying? Mellow is free on iPhone and Android. Whatever you pick, read the store listing to see what's included and what isn't.

10. Does it feel calm to use?

A migraine app should lower your mental load, not add to it. That means a clean screen, a dark mode that doesn't hurt on a sensitive day, and reminders that don't make you feel guilty if you skip an entry.

This one is subjective, but it matters, because you'll only keep logging if opening the app doesn't feel like a chore. Some apps also include educational content. Mellow offers short courses to help you understand, prevent and manage migraine. They're a complement to medical advice, not a replacement.

What an app can't do

A migraine app can help you notice patterns, but it can't diagnose you, treat you or tell you what medication to take. Be sceptical of any app that promises to "cure" or "prevent" your migraines on its own.

Here is what a tracking app can reasonably do:

Save you time and memory by keeping an organised record.
Show patterns in timing, duration, intensity and possible triggers.
Give you something concrete to bring to an appointment.

And here is what it can't:

Replace a medical assessment. The NHS says a GP needs to identify a pattern of recurring headaches along with the associated symptoms, which is exactly where a diary can support the conversation.
Prove what causes your attacks. Correlation in a diary isn't proof, and triggers can change.
Decide on treatments. For questions about medication, talk to your doctor or pharmacist. Our overview of migraine medication explains the options in general terms.

Also remember that new or sudden symptoms need medical attention, not an app. If you're unsure, our guide on when to go to the ER for a migraine can help you decide.

How to test a migraine app in one week

You can judge most apps in about a week, even if you don't have an attack in that time. You don't need to wait for a migraine to find out whether an app suits you.

Day 1: Download one or two apps. Read the store description and privacy policy for a few minutes. Check what's free.
Days 2 to 3: Enter a past attack from memory. Is it quick? Are the questions clear? Does it feel natural?
Days 4 to 5: Add daily notes (sleep, stress, cycle, anything relevant). Does that feel light or heavy?
Days 6 to 7: Look at the statistics and the report. Would you be happy showing this to your doctor?

If an app feels annoying after a week, it will feel worse after three months. Switch early rather than late, and don't be afraid to try another. Just be consistent with one app at a time, so your history stays in one place.

Choosing without pressure

Choose an app that's quick, honest about its limits and kind to your data, then give it a few weeks. There is no single winner for everyone, and no app will fix your migraines.

If you remember only three things, make them these: log fast, keep it simple, and share what you've learned with a healthcare professional. The best migraine app is a quiet helper that lets you see your own pattern more clearly, and gives you more to say in the consulting room than "I get a lot of headaches".

And what about Mellow?

Mellow is this site's app, and it was designed around these criteria. Here's how it measures up:

Quick logging: you record an attack in two taps, even in the middle of one.
Triggers: you track stress, sleep, screens, your cycle and food.
Barometric pressure: it's tracked automatically, so you don't have to enter it.
Statistics and history: calendar, duration, intensity and trends, plus a report for your doctor.
Price and platforms: the app is free, available on iPhone and Android, and also offers courses to help you understand, prevent and manage migraine.

If you'd like to judge for yourself, try it for a week using the method above. If you open it without having to think about it, that's a good sign. If not, you'll at least have learned what matters to you.

Frequently asked questions

Is there a good free migraine app?

Yes, many migraine apps are free, and the Migraine Trust says that some free apps are good options for keeping a diary. Check what "free" includes, such as ads, data sharing, or features locked behind a subscription. Mellow is free on iPhone and Android.

Do I need an app, or is a paper diary enough?

A paper diary is enough if you'll use it. The American Migraine Foundation lists apps, spreadsheets and written journals as valid ways to track migraine, and the best format is the one you keep up with. An app mainly adds speed, automatic data like weather, and charts.

Can a migraine app diagnose my headaches?

No. According to the NHS, there is no specific test for migraine, and a GP makes the diagnosis by identifying a pattern of recurring headaches and their symptoms. An app can help you record that pattern, but it can't replace a medical assessment.

How long should I track my migraines before seeing results?

The NHS says that keeping a diary for a few weeks can help with diagnosis. The Migraine Trust suggests three months or more to work out your triggers. Don't wait for perfect data before talking to a doctor if your migraines are affecting your life.
