Retrievr is a mobile application that works in tandem with a QR enabled pet ID tag. Users can create profiles for their pets and let users in their community know if their pet has gone missing. In that, any user that has a home location close enough to the last known location of the missing pet can be notified that a pet has gone missing and will know to look out for this lost pet and hopefully help the user find their furry friend. If a user comes across an animal that appears to be lost that has a Retrievr QR tag on their collar, that user can scan the tag and immediately let the owner of the pet know that their companion has been found and give them the information necessary to reunite.
