While things like parking reminders, proper timer management, and bill pay reminders have already seen their public release, the ability to set contact-based reminders ("remind me when I'm with this person"), hasn't come forward yet. But it will likely appear very soon with a new feature in Android called Nearby, which will allow new interactions between you and nearby people, places, and things.

We've received information indicating that Nearby will come with an upcoming Google Play Services update. While we still caution readers that anything related to a leak can change, we are not treating this as a rumor, as our information is reliable and complete enough to inspire full confidence that this functionality will be revealed (in an official capacity) soon.
