Do you have too many friends? Is your social life a constant hassle of unwanted drinks and awkward excuses as to why you're sorry you "can't be there next Thursday"? Then you need to ruthlessly cull your contact list with Pplkpr.
No, it's not the latest rent-an-assassin service to slip through the Apple Store checks.
Using a GPS tracker and a heart rate monitor, Pplkpr (pronounced "people keeper") claims to track, analyse, and auto-manage your relationships. Measuring subtle changes in your heart rate variability, the app prompts you to record who you're with when it detects fluctuations in your emotions (or rather, heart rate).
By monitoring your stress levels and cross referencing them with who you've been hanging out with, Pplkpr provides feedback on who you should spend more time with and who causes you the most stress.
Is it 100 percent accurate? Most definitely not. Couldn't you figure this out by yourself? Certainly. But it's an interesting new development in the weird world of quantified living. If you want to try Pplkpr, you can download it here.
And we'll go on record to suggest it being the cause of a nasty argument between you and your significant other/parents/sibling upon the inevitable discovery that the time you spend together is the cause of "deep anxiety".
