Check your relations

You open up the little device and see a little blinking app.

It's a tracker app, it shows you how much time you've spent where and with whom.

"That's pretty neat" you think to yourself.

You scroll down a little and by each person, there are little hearts and bars.

"Huh, what?"

The app explains that it's also tracking the heartbeats of other users on their devices and checks for compatibility. 'It's very useful when dating in the resort ;)'
Enjoy!
