The big idea
Fitness trackers use AI to interpret what your body is doing. It is mostly accurate but not always. And the data goes to the company — which is a privacy thing to think about.
Some examples
- AI estimates your sleep stages from heart rate variation (mostly accurate, sometimes way off).
- AI counts your steps (good for walking, less good for biking or skating).
- AI detects irregular heart rhythms (Apple Watch has actually saved lives).
- AI predicts when you might be getting sick based on subtle changes.
Try it!
If you have a fitness tracker, look at what data it has on you. With a parent, check the privacy settings. Decide together what data you are comfortable sharing.
