A practical buyer's guide to the best migraine tracking apps in 2026, covering what features matter most for people on CGRP preventives and how to evaluate your options.
Finding the best migraine tracking app in 2026 is harder than it should be. There are dozens of options, and they are not all solving the same problem. Some are detailed symptom diaries. Some focus on mood and wellness. A smaller set is built specifically for people on migraine preventive therapy who need to show clinical progress. This guide reviews the leading apps honestly, covers what makes the best migraine app for iPhone, and helps you match the right tool to your actual situation.
Before you compare apps, be honest about what you actually need. Most people fall into one of three groups.
Occasional migraine sufferers want simple logging: date, severity, medication taken, how long it lasted. Any basic app works here.
Chronic migraine patients on preventive therapy need much more. You are collecting evidence. Every attack you log is a data point your neurologist uses to evaluate whether your treatment is working. Gaps in your log are gaps in your case.
People on CGRP preventives specifically have a third layer. Many CGRP medications require annual prior authorization renewals, and insurers want proof of effectiveness: monthly migraine days (MMD) before and after treatment, percent reduction, disability scores. If your app cannot produce that documentation, you are building it manually every year, usually right before a renewal deadline.
See our deep dive on CGRP prior authorization renewal for what that documentation typically looks like.
Migraine Buddy is one of the most widely used migraine diary apps available today. It has a large, established user base and covers the core use case well: logging attacks with detailed symptom capture, tracking potential triggers, and reviewing patterns over time. The attack timeline visualization is a standout feature for understanding how an attack progresses across phases. Trigger correlation tools help identify patterns over weeks and months.
Where Migraine Buddy is strongest: general diary use, trigger exploration, and getting a clear visual picture of your migraine history. It is available on both iPhone and Android. The free tier covers basic logging; a paid subscription unlocks reports and some analytics.
Best for: people who want a polished, full-featured diary with a large community behind it and are not primarily focused on CGRP renewal documentation.
Bearable is a broad symptom and health tracker that many people with chronic illness use, including migraine patients. Its flexibility is the main draw: you can track essentially any symptom, correlate it with sleep, mood, medications, and dozens of other variables, and visualize correlations over time.
The trade-off is that Bearable is not migraine-specific. Monthly migraine day counts, MIDAS/HIT-6 scoring, and clinical-format exports are not built-in features. If your primary need is documenting migraine frequency for a neurologist, you will likely need to extract and reformat that data yourself.
Best for: people who want a single app to track migraines alongside other health conditions (fatigue, mood, sleep) and are comfortable with a more manual approach to clinical documentation.
N1-Headache takes a research-informed approach to headache tracking. It was designed with input from headache specialists and structures the logging process around standardized clinical data: headache days, severity, associated symptoms, medication use, and potential overuse patterns. The app surfaces medication overuse headache (MOH) risk as a built-in feature, which is genuinely useful and not common in general diary apps.
N1-Headache skews more clinical in its interface, which some users find useful and others find dry. It is available on iPhone. Report export is available, though the format is more basic than a fully structured renewal document.
Best for: patients who want a clinically structured diary, are working to understand MOH risk, or whose neurologist values standardized headache logs over narrative-style exports.
Migraine Monitor is produced by the American Migraine Foundation, which gives it a level of clinical credibility that independently developed apps often lack. The app covers standard diary functions: attack logging, symptom tracking, and medication recording. It also generates a Migraine Report Card, a structured summary you can bring to appointments.
Because it is backed by an established patient advocacy organization, it tends to stay current with clinical guidelines. The interface is functional if not flashy. It is available on iPhone.
Best for: patients who want an app with direct organizational backing from the headache medicine community, or who prefer bringing a formatted report card to appointments rather than raw data.
This is our app, so take the framing with appropriate skepticism. Migraine Tracker: CGRP Log was built from the ground up for one specific patient: someone on a CGRP preventive who faces annual prior authorization renewals. If that is not you, there are better general diary options above.
If it is you, the app automates the documentation that renewal requests require: monthly migraine day counts using the clinical definition, percent reduction from your pre-treatment baseline, breakthrough medication days, MIDAS and HIT-6 scores, and adherence. It produces a formatted PDF report your neurologist can attach to a renewal request directly.
Data stays encrypted on your device. A revocable care-team link lets you share your log with a provider without printing or emailing anything. The logging interface is designed for fast input during an attack: minimal taps to record the essentials when your head is not cooperating.
Best for: people on CGRP preventives (erenumab, fremanezumab, galcanezumab, eptinezumab, atogepant, rimegepant as prevention) who need to document clinical outcomes for insurance renewals each year.

The query "best migraine app for iPhone" has a specific meaning: Apple ecosystem depth matters. iPhone users reasonably expect apps to integrate with Apple Health, support Apple Watch for quick logging away from the phone, offer Home Screen and Lock Screen widgets for fast access, and potentially use Live Activities to track an active attack in progress.
Here is how the apps above compare on Apple ecosystem integration:
Apple Health integration lets your migraine data live alongside sleep, heart rate, and activity data, which matters both for personal pattern tracking and for any future care coordination. Not all apps write to or read from Apple Health natively.
Apple Watch support is a meaningful differentiator for iPhone users. Being able to log the start of an attack from your wrist, especially when reaching for a phone feels like too much, is not a gimmick. It changes what actually gets logged.
Widgets (Home Screen and Lock Screen) let you see your recent migraine count at a glance without opening the app, which is useful for staying aware of monthly counts especially late in a billing cycle when you are close to the threshold your neurologist watches.
Live Activities can track an active attack duration on the Dynamic Island or Lock Screen, giving you and your care team a more accurate attack length without having to remember to log the end time later.
Among the apps above, Migraine Tracker: CGRP Log is built specifically for iPhone and Apple Watch, with native Apple Health integration and widget support. Migraine Buddy also has iPhone and Apple Watch support. If Apple ecosystem depth is a priority for you, check both apps directly, as feature sets update regularly.
For a broader look at how to track migraines accurately regardless of device, that guide covers logging discipline and common pitfalls.
This sounds basic. It is not. Some apps count headache days. Some count attack events. Some count calendar days with any head pain. The definition that matters clinically is a calendar day with a migraine lasting four or more hours untreated, or any duration if abortive medication is taken. Your app needs to count this correctly or your MMD numbers are wrong.
Read more about how monthly migraine days are defined and tracked.
You need a documented pre-treatment baseline to show improvement. If you started a CGRP preventive six months ago and only began tracking last month, you have no baseline. Good apps prompt you to establish a baseline period, or at minimum log clearly when your treatment started.
Both disability scoring tools are standard in neurology practices. An app that auto-calculates them from your log means you walk into every appointment with current scores rather than filling out paper forms from memory. For more on these tools, see MIDAS and HIT-6 explained.
Your data is useless if it lives only on your phone. PDF export, shareable reports, or a direct care-team link gives your neurologist something to attach to a renewal request. This is a dealbreaker feature if you are on a CGRP preventive.
You are not going to fill out a five-screen form when your head is splitting. Apps that take two taps to log an attack get used during attacks. Apps that require more friction get filled in the next day from memory, which is less accurate. Look for a one-tap or minimal-input attack mode.

Medical data is sensitive. Check where your data is stored, whether it is encrypted, and whether you can delete it. Encrypted on-device storage with optional encrypted sync is the safest architecture. Understand what the app does with your data before you start logging.

Migraine Tracker: CGRP Log (PixelPort LLC) was built from the ground up for people on CGRP preventives. It auto-builds the prior-authorization renewal report from your logged data, calculating MMD, percent reduction from baseline, breakthrough medication days, MIDAS, HIT-6, and adherence. Data stays encrypted on your device. A revocable care-team link lets you share your log with your neurologist without printing or emailing anything. Get the CGRP renewal report or download the app.
Educational, not medical advice. Migraine Tracker: CGRP Log is a personal tracking tool, not a medical device. It does not diagnose, treat, or provide medical advice. Always talk to your clinician.
The best app depends on your situation. For people on CGRP preventives who need prior authorization renewals, an app that auto-builds renewal reports and tracks monthly migraine days is far more useful than a general diary.
