I'm looking for thinnest tracking device such as TrackR sticker to be able to tag multiple objects, then track them down using some smart app. For example for organizing or locating the lost items. So basically it should allow me to apply a unique name. Item ringer (ring activated by app) would be an advantage.
I've been using TrackR, but I had some issues when item ringer was activated by itself.
So I'm curious if there are some alternatives to it.
