Gone are the days of lost dog posters taped to street lamps and telephone poles. Finding Fido is an app that provides a modern way of reuniting lost dogs and their owners. Whether your dog has gotten away or you've found one roaming around the neighborhood, you can upload its picture to this app and it will search the database to see if there's a match. If not, users will receive a notification the moment a match is uploaded. Finding Fido uses facial recognition to reunite wandering pups with their worried owners.
