My 15-year-old daughter wants a fitness tracker, like a fitbit. But I know there are a lot of other options as well. Doesn't have to be too fancy, but wants steps, heart rate, sleep monitoring, stopwatch, and some other probably pretty standard features in a fitness tracker.

Any of you have one, or have one for a family member that isn't really high-end, but is solid and you/they like? Price range from around $50-$100, but if there's a decent one for less than $50, I'd be all for it.
