Do you own a CryptoKitty? Have them always with you as a watch face! Make sure you first specify the kitty id on the app settings though.

To get a kittie ID you can go to https://www.cryptokitties.co/marketplace, click on a kitty and get the id from the URL in your browser (e.g. https://www.cryptokitties.co/kitty/469927, in this case ID is 469927) or you can just set the ID to 1 if you want the genesis cat.
