Kit is the first Apple Watch app from NPE Team, Facebook’s research and development group. The team was responsible for meme-making app Whale, a chat service called Bump and social music listening tool Aux. More recently, it released Tuned, an app for couples to share things in private with each other. 

The availability of NPE Team apps varies on a case-by-case basis. However, Facebook isn’t shy about shutting down experimental apps that don’t take off, so if you’re interested in trying out Kit, it might be best to check it out swiftly if it’s on your local version of the App Store.
