The big idea
A fitness tracker on your wrist counts every step and heartbeat all day. AI inside it can spot patterns — but it can also share that data with companies.
Some examples
- Tracker notices your heart rate jumped while sitting still — interesting clue
- It can tell when you slept badly and suggest you rest
- It shares some of that with the watch maker
- It is not a doctor — never diagnose yourself with it
Try it!
What is one thing a tracker should NOT share with anyone?
