Keysaver

Everyone loses their keys every once in a while, especially with the serious prevalence of Alzheimer's in the elderly.

This is a perfect key proximity sensor for retirees - I hate missing my keys! Work to pay your bills & find your keys in a reasonable amount of time without all of that frou-frou - no more digging under car seats & in couch cushions. Crack open the app, and it will 'scream' beeps with more urgency as you get 'warmer' (closer to the RFID-chipped keyfob) such that you get in touch with your own keys.

I recommend this as a gift to older folks as they especially hate missing keys (understandably). Made in memory of my late & deceased grandparents, may they rest in peace.
