I featured this item when it first came to the market, but it is such a great idea, that I am featuring it again.  How many times have you lost your keys, and, in my case I never remember where I put my coffee cup.

Tile is a Bluetooth tracker that helps you locate misplaced items so scatterbrains on both iOS and Android can get some peace of mind. Each Tile costs $25, and can be attached to any item you are afraid of losing: phone, purse, car, laptop, car keys, baby, etc.

The app is free.  So you ask, “how can I use the app to find my phone if the app is on my phone?”  Great question.  You can use a friend’s phone to find your phone.  You can also program your tile to ring. 

I can’t think of a more useful gift.  Oh, by the way, I wonder if the tile can be slipped into your teenager’s pocket?
