The Eta Clock tells you where your family members are, just like in Harry Potter

The Eta Clock is a new Kickstarter project from a startup called DC Creatives that works

with a smartphone app to show you the locations of your friends and family members, using a fun, clock-style interface. So basically, it’s a real, functional version of the Weasley family’s magical clock from the Harry Potter series. And — putting aside the fraught social issues of needing to know your family member’s locations — it’s kind of amazing that it exists. While it’s worth pointing out that the Eta Clock is by no means the first to emulate the Weasley family’s tracking timepiece, it is (to the best of my knowledge) the first product that is ostensibly being sold to consumers. (Unless the Kickstarter crashes and burns, that is.) Unlike Mrs. Weasley’s version, the Eta Clock relies on modern technology rather than actual sorcery to accomplish the job. Using a companion app, each user can set specific locations on their phone corresponding to places like “work,” “gym,” or “school,” along with more general categories like “abroad” (when someone is outside their home country), “transit” (if the individual is traveling faster than three miles per hour), or “lost” (if the person’s phone hasn’t updated location in more than five days).                                                                                                         https://www.theverge.com/2017/9/6/16262010/eta-clock-kickstarter-harry-potter-weasley-family-track-locations-traveling
