Participate
Not open yet. Here is what it will involve.
Contributing should take one careful read and a few taps, then nothing. No daily logging, no extra exercise, no watch required. This page is the whole of what we will ask.
What you will do
1. Understand
Who runs this, what is collected, who sees it, the main privacy risk, and that this is not medical care. The whole explanation fits on one screen, with the full notice one tap away.
2. Confirm and choose
Confirm you are an adult. Choose which measurements to send. Optionally give your age bracket and region, each with the reason it is asked. Nothing is bundled; you can send steps and nothing else.
3. Allow the phone
Grant the health store read access for the categories you chose. Agreeing to contribute and letting the phone share are two different permissions, and the app shows you both.
4. See the first contribution
The app shows what was actually read and the first successful sync. Not a green check mark: the real date and the real number.
Which phones
| Platform | Source | Status |
|---|---|---|
| iPhone | Apple Health | First release. Apple Watch optional; adds resting heart rate. |
| Android | Health Connect | Second release, same measurements and same map. |
| Watch or fitness apps directly | Vendor cloud services | Not planned. Everything they hold already lands in the phone's health store. |
What you get
- A weekly card: your week, your age group's week, and this week against your own last twelve.
- Where you sit in the distribution for your age group, shown as the whole distribution, not a rank.
- After twelve months on the map, your own trajectory drawn against the age curve.
- A complete export of everything you contributed, any time.
- The same public map everyone else sees, inside the app.
What you do not get: coaching, targets, streaks, scores, or predictions. The app never tells you whether you moved enough.
