Activity tracking
Why has apple not made an extremely durable ankle bracelet that tracks your steps, heart rate, etc. basically does everything an Apple Watch does but send the data to the iPhone and can be wore during sporting events that wouldn’t allow an Apple Watch.
I would guess that it would generate an enormous chunk of money and you could get a famous athlete to sponsor it. Plus, it furthers demonstrates that apple truly believes in people’s fitness. I see no downside to the creation of this product and hope you take my comment into serious consideration. I would indefinitely buy one and I’m sure other athletes like me would as well.
-Have a great day thanks
