If the parent meant to do those things without bringing the phone along for the run then the PineTime wouldn't work since it has no onboard GPS or enough storage for music.
There's not a lot to review, it's pretty bare bones. It has a clock, heartrate sensor, and can tell you notifications. I only really use it for the time and notifications, since that's all I really want from a watch. Battery lasts around a day and charges to full in like 30 minutes.
