Blue Jay is an iPhone app designed by Santas AI Lab Inc. It falls under the Social Networking category and offers a unique feature of providing feedback on photos. Users can upload selfies to receive feedback on their energy levels or share pictures of outfits to enhance their style. The feedback received can be shared within the Blue Jay app or externally.

In addition to photo feedback, Blue Jay incorporates a novel chat feature where a photo is taken every time a message is sent or received. These photos are analyzed but not shared, providing users with descriptions of the person they are chatting with at the time of messaging.
