Very simple Fitbit/tracker for older person

[GoingOnce]

Hi, can anyone recommend an activity tracker for an older person who just wants to track steps, distance, calories and see the time?

I’m scrolling through Amazon and there are so many!

Distance won't be accurate unless you use GPS - some that only count steps give a distance but it will be very estimated and assumed based on stride length. Some watches track distance if you use the GPS through your phone and others have it built in but they tend to be more expensive. Likewise calories are more accurate if they have built in heart rate monitoring but are even more accurate if you use a HR chest strap monitor for exercise.
If steps and just being a bit more active is your main goal then I'd for something like a Fitbit Charge.
