Petkey hosts the largest Nationwide missing pet network. Lost and Found pets can be listed for free in an effort to get the word out quickly and reunite missing pets with their families. If you are missing a pet you can view our live map of found pets to see if your pet has been recovered. If you have found a pet and are looking for their family you can add that pet to the map to help get the word out and reunite that pet. Every second counts so add your pet to the network today their profile is prepared in the event of an emergency. Having a profile for your pet will also provide you with quick access to your pet's important details and virtual ID. Once your pet is in the network you can receive immediate notifications if your pet has been found. You can also have some fun with it and create a custom Petmoji of your pet.

Liz turns a spare tablet into an always-on display for someone with memory difficulty, and keeps their family in the loop from anywhere. The tablet sits on a kitchen counter or a bedside table, showing today's reminders in large, readable text and a rotating slideshow of the people who love them. There is nothing to unlock, nothing to open, and nothing to remember how to use. It is simply on. From your phone, you send the reminders and the photos. FOR THE PERSON USING THE TABLET • Today's reminders, in type large enough to read across a room • Tap one to check it off — that is the entire interface • A slideshow of family photos, each captioned with who is in it • An undo button, for when something gets checked off by mistake FOR THE FAMILY • Send a reminder from your phone - once, or repeating daily, weekly, monthly or yearly • Schedule one to appear at a particular time • Mark a reminder important so it stays at the top of the display • Add photos with a caption: who is in it, how they are related, where it was taken • Get a notification the moment a reminder is checked off • Find out if the tablet goes offline • Everyone caring for the same person shares one view, so nothing is doubled up SETTING IT UP Install Liz on a tablet, choose "Set up a Liz device", and share the four-digit code with your family. Anyone who enters it can help. Liz contains no advertising, no analytics, and no tracking of any kind.
