Samsung SmartTag 2 Black

I bought this Smarttag for my father with early Alzheimer's. Unfortunately, it sometimes gets lost. A nice compact thing that can easily be hung on a bunch of keys. We first tested it ourselves, but unfortunately it does not work at all for this purpose. No movement of the tag was visible on my mobile phone screen, while my husband had walked quite a distance from home to check how accurately it indicates the location. So just buy a GPS tracker.

I sometimes use it a bit inaccurately for the keys of an Alzheimer patient, but that probably also has to do with how many Samsung phones are nearby

Installed on a Samsung phone and then installed on another Android phone, which unfortunately does not work. Tag can only be used with/on a Samsung Galaxy device
