If you wear more than one device, you may end up with two or three places that all measure the same thing. For example: your Apple Watch counts steps, your Oura ring also counts steps, and your phone counts steps too. MigraineMe needs to know which one to trust.
Do not worry. You do not need to choose this on day one. MigraineMe makes a sensible guess on its own. But if you find your numbers look strange, here is how to take charge.
What "primary source" means
A primary source is simply the device or app you want MigraineMe to use first for a certain type of data. You can pick a different primary source for each piece of data. For example:
- Sleep from your Oura ring.
- Steps from your Apple Watch.
- Heart rate from your Garmin watch.
You decide. MigraineMe will only listen to that one and ignore the rest for that metric.
On iPhone and Android
The steps are the same on both phones.
- Open MigraineMe.
- Tap the gear icon in the top-left of the screen.
- Tap Data and Notifications.
- Open the section that holds the metric you want to set (for example Sleep or Physical Health).
- Find the metric row. Underneath its name you will see a small green pill badge showing the current source (for example "Apple Health", "Oura", "Garmin").
- If you have more than one source for that metric, the badge has a small chevron. Tap the badge.
- A menu opens with all the sources that are writing that metric. Tap the one you want MigraineMe to use.
Do the same for any other metric where you want a particular device to lead, like Heart Rate, Steps, or HRV.
If the badge has no chevron
If only one source is writing that metric, the badge is fixed. There is nothing to pick. MigraineMe just uses what it finds. The chevron appears once there is more than one option.
A practical example
Let's say you wear an Apple Watch every day, and you also recently bought an Oura ring. You like the Apple Watch for steps, but you trust the Oura ring more for sleep. Here is what you would do:
- Open the gear icon top-left, then Data and Notifications.
- Open the Sleep section. Find Sleep duration. Tap its green source badge. Choose Oura.
- Open the Physical Health section. Find Steps. Tap its green source badge. Choose Apple Health (the source that the Apple Watch writes to).
From now on, MigraineMe will read your sleep from Oura and your steps from your watch. The two will not fight.
Changing your mind
You can change the source any time. If you replace your Oura ring with a Garmin watch, just come back to Data and Notifications and pick Garmin as the new source for sleep. Your old data stays. The new readings just start coming from a different place.
If your numbers look wrong
- Open the gear icon top-left, then Data and Notifications.
- Open each section and check the green source badge under each metric.
- Make sure the device you actually wear is the one shown on the badge.
- If not, tap the badge and choose the right one.
That fixes most "my numbers look weird" problems in one minute.
