Recalibration is one of the quiet, clever things MigraineMe does in the background. In plain English, it is the app re-learning what matters for you, now that it knows you a little better than it did at the start.
You do not need to understand the inner workings. But it helps to know what is going on, so when you see the word "recalibration" pop up in the app, you know what it means.
This article is just an explanation. There are no steps to follow.
The short version
When you first started using MigraineMe, the app made educated guesses about what might trigger your migraines. These guesses were based on averages from many people with migraine, plus the answers you gave during the AI setup questionnaire.
Over time, the app gathers more information from you: the migraines you have logged, your sleep, your watch data, your weather, your food. Once a week, if you have Premium or are on your free trial, the app pauses and asks itself:
- Were my first guesses correct for this person?
- Are there better numbers I could use now?
- Are there new patterns I missed at the start?
That pause is recalibration.
What it actually changes
When MigraineMe recalibrates, it can suggest small adjustments such as:
- The thresholds at which a trigger starts to count. For example, the app might learn that for you, a poor night's sleep only matters below five hours, not seven.
- The importance of certain triggers. Caffeine might matter less for you than the app first assumed. Stress might matter more.
- The favourites in your pools, such as the medicines and reliefs you reach for most often.
- The decay curves, which decide how quickly the risk of a past trigger fades over the days that follow.
- Your clinical profile, which is the little summary card on your Profile screen.
These are small numbers and lists deep inside the app. You will never need to touch them yourself.
You always have the final say
The app never changes anything on its own. When it has new suggestions ready, you will see a small banner on the home screen, and a push notification telling you the weekly check-in found something. Tapping the banner opens a review screen where you can read each suggestion in plain words and tick the ones you want, or untick the ones you do not.
Nothing is applied until you tap the Apply button at the bottom of that screen. If you simply close the screen, nothing changes.
When does it happen?
The check runs once a week, on Mondays, for Premium and trial users. But a check is not the same as a suggestion: the app only prepares suggestions when your data has genuinely shifted. Many weeks it will look, find nothing meaningful, and stay quiet. That silence is normal and healthy.
If you have just connected a new wearable, you can often expect suggestions within a week or two, because there is suddenly a lot of new data to learn from.
If you want a fresh start sooner, the Redo Onboarding card on your Profile screen takes you back through setup and recalibrates your profile.
Why do this at all?
A migraine pattern is personal. No two people share the same triggers, in the same amounts, with the same recovery curve. Recalibration is the part of the app that gently bends the model to you, instead of leaving you with the average.
You do not need to do anything special. Just keep logging, and the app will take care of suggesting changes when it has something useful to say.
