A migraine tracker should make daily recording easier, not turn it into another demanding task. Test whether you can log the important details on a bad day, understand where the data is stored and export a summary your clinician can read. If you are new to tracking, read what a headache diary records and how digital and paper diaries compare.
Start with the clinical basics
- headache and migraine-like days
- start time, duration and intensity
- nausea, aura, light sensitivity and sound sensitivity
- effect on work, school, sleep or care tasks
- acute medication, dose, time and response
Daily records can be more reliable than estimating an entire month from memory. In a prospective clinical study, patients' estimates of migraine days, other headache days and acute medication days differed from their electronic diary counts. The diary helped describe the pattern; the physician's interview and examination remained the diagnostic standard.
Treat triggers as questions
Custom fields for sleep, menstruation, stress, meals, caffeine, alcohol, weather or sensory exposure can be useful. More fields do not automatically produce better answers. In a 90-day prospective diary study, many common candidate triggers had weak or noisy relationships with the next migraine attack.
Look for an app that shows the underlying dates and counts rather than declaring that a correlation is a cause. Change one practical factor at a time when you and your clinician decide that a pattern is worth testing.
Check privacy before entering health data
- Is an account required?
- Is data stored on the device, in a private cloud account or on company servers?
- Which analytics or advertising services receive app data?
- Can you export and delete your records?
- Does the company sell or share data, including aggregated data?
An account is not automatically unsafe, and local storage is not automatically backed up. Choose the trade-off you understand. Privacy in health apps explains what to check in more detail.
HeadYogi stores its records on the iPhone or in the user's private iCloud account. It does not require advertisements or third-party trackers and does not sell user data. Verify the current policy and settings before relying on any app, including HeadYogi.
Make sure you can use the data
A readable PDF is useful when you need a summary for an appointment. CSV export gives you row-level data that you can open in a spreadsheet or move to another tool. Check whether the app lets you select a date range and whether the report clearly shows headache days, acute medication days, intensity, duration, associated symptoms, functional impact and missing entries.
Do not assume a clinic can import a CSV into its health record. Ask what it accepts. See how to prepare a short headache report and how HeadYogi supports clinician reports.
Test the app on a difficult day
- Start an entry with reduced screen brightness.
- Record medication without completing every optional field.
- Correct a mistaken time or dose.
- Export a two-week report.
- Find and delete an entry.
Core logging should work offline if you need it away from a connection. Reminders should be optional. Check recent stability reports, but remember that store reviews do not verify clinical accuracy or privacy claims.
Warning signs in a tracker
Avoid an app that claims it can diagnose, treat or cure migraine from diary data. Be cautious when it labels a trigger without showing enough observations, hides export behind an unclear process or makes deletion difficult.
A tracker also cannot decide whether a symptom is an emergency. Seek urgent medical help for a sudden extremely painful headache, new neurological symptoms, fainting, fever with severe headache, headache after injury or a clearly changed pattern.
Start small
Begin with headache day, duration, intensity, symptoms and medication. Add one or two context fields only when they answer a real question. Review the record after two to four weeks and take it to your clinician rather than making treatment changes from an automated insight.
HeadYogi is one option built around quick logging, local or private iCloud storage and PDF or CSV export. Review HeadYogi's features, how it works and the download page if those choices fit your checklist.

The best tracker is the one you can use consistently, understand and discuss with the clinician treating your headaches.
