When you open MigraineMe, near the top of the home screen you see a half-circle dial with a number inside it, for example 3.4. That number is your risk score for today. It is a friendly way of saying:
"Based on what we know about you so far, here is how likely it looks that a migraine could happen today."
You can think of it like a weather forecast. The forecast does not promise rain. It tells you the chance of rain so you can decide whether to bring an umbrella. The risk score works the same way.
What the colour means
The dial itself stays purple. The level is shown by the coloured word just under the number. There are four levels:
- Negligible (grey) means MigraineMe does not see any clear risk signals today. Often the case on quiet, well-rested days.
- Low (green) means a quiet day for your body. No special action needed.
- Mild (orange) means worth paying attention. A good day to drink water, eat regularly and not skip sleep.
- High (red) means be gentle with yourself today. Rest if you can and keep your medicine nearby.
You do not need to memorise the exact numbers. The colour and word are what matter.
What goes into the score
The score is built from the triggers and early warning signs (prodromes) that have been logged for you over the last seven days. Some of these you log yourself, and some the app spots automatically. The main ingredients are:
- How you slept last night and over recent days
- Your heart and stress signals if you wear a watch or ring
- The weather where you are, especially changes in air pressure
- What you ate or drank if you log meals or connect a food app
- Your menstrual cycle, if you track it
- Things you have told us trigger you in the past
Each item counts for more when it is more severe and more recent. A trigger from this morning weighs a lot more than one from six days ago. You do not have to give the app all of these to start. The more pieces of the puzzle it has, the better the score becomes over time.
Tapping the circle for more detail
The dial is a button. Give it a tap.
- A screen called Risk Detail opens.
- You will see a list of everything pushing the score up today, in order, with a small bar showing how much each one is adding.
- You will also see the 7-day forecast, a row of small gauges for today and the days ahead.
- From there, tap History at the top to see how your score rose and fell over the past two weeks.
If you scroll down on the home screen, you will also see a card called Top contributors. It shows the top three items in a shorter form so you do not have to tap in. The full breakdown, the forecast for future days and the Top contributors card are part of the premium plan; today's score itself is always free.
Why the score changes during the day
The score is not frozen at the moment you wake up. It refreshes as new information comes in. For example:
- A poor night of sleep can bump it up in the morning
- A drop in air pressure as a storm rolls in can push it up later in the day
- A coffee logged at lunch may shift it again
If you have just connected a new wearable or food app, give the score a few days to settle. It needs time to learn what a normal day looks like for you.
"But I had a migraine on a green day"
This will happen sometimes, and it does not mean the app is broken. Migraines have causes we cannot all measure yet. A green day means less likely, not impossible. Please always trust your body first and the score second.
If the score stays at 0.0
A score of 0.0 with the word Negligible means nothing is adding to your bucket right now.
- Make sure you have logged something. A brand new account has no data yet, so there is nothing to score.
- Refresh. On iPhone, pull down on the home screen to refresh. On Android, close the app fully and open it again.
- Check your internet connection. The score is calculated in the cloud, so the app needs a moment to fetch it.
If you have logged triggers and the score still shows 0.0 after a full day, please write to us at help@migraineme.app and we will take a look.
