Hi everyone. My 12yo wants a Fitbit/activity tracker to wear. I grabbed one on amazon, but have realized now that you have to manually press the button any time you go on a long-ish walk. This is kind of useless. I was hoping for one that will just sense his movement and track his steps. Does anyone have a recco for one that’s not too expensive, but will be automatic? I’ll read through reviews on amazon, but figured I could ask you guys too. Thanks!
