I can’t begin to tell you how much time I have spent in the 12 years since my husband first exhibited symptoms of Mild Cognitive Impairment, searching for lost keys, wallet, etc. A couple of years ago our son & wife gifted me with a couple of Tiles to put on our key rings. Woah! Downloaded the Tile app to my phone and BINGO! I can track down the keys, even if he hides them under the mattress! Now we have one on keys, in his wallet, my keys ( which he sometimes puts in a “safe” place), TV remote, & spare key to open dead bolt from inside. Now if they just made one for his glasses 😜. AND… I can find my phone from any of those Tiles. A real timesaver!
