PassCall was created to mimic the chance interactions that we may have previously experienced with your best friend. PassCall is meant to trigger short interactions (“a call”) between close friends in response to those friends simultaneously walking by (“passing”) their respective devices, just as if—by chance—they walked by each other in another context (e.g., a hallway at school, or at the grocery). Forget scheduling your video calls with best friends  in advance: let PassCall help promote and re-develop those relationships with our patented technology.
