Pplkpr ranks relationships by tracking how they affect your heart rate | Daily Mail Online

Called pplkpr, or People Keeper, it syncs with a heart rate monitor to track subtle changes in emotional state.

Pplkpr notifies the wearer when it detects heightened emotion, and asks them to report how they’re feeling.

Using GPS, it also notifies them when they change locations, to ask if they’ve just left, or are about to meet someone.

The measurements are based on a metric called ‘heart rate variability’, where subtle changes in heart rhythm signal changes in an emotional state.

Pplkpr knows when the wearer is experiencing a strong emotion, but lets them decide what that emotion is.

Once established, pplkpr can write text messages, invite people to hang out, or block or delete contacts.

All of these actions are shown on the home screen before they take place.
