This iOS app predicts your death with HealthKit data

Apple's latest push is to make you as healthy as possible -- or at least give you the tools to do so -- but a new app will read your newly available HealthKit data and use it for a more sinister purpose: predicting your death. The app is called Deadline, and it uses health statistics, along with your own personal readings to make an educated guess on when you'll meet your demise.

Once your numbers are crunched, the app produces a rather grim timer which ticks down by the second. It's a bit creepy, to be honest, but the good news is you can push the date back by being healthier. Lose a few extra pounds, get more sleep, and ditch the ice cream for some fresh fruit and you'll notice that days, months, or years are being added to your life. It's a strange bit of motivation, but if it works for you, go for it!
