Happy Halloween! We’re all going to die someday!

At least that’s the conceit of a new $1 iOS app called Deadline. It culls information from Apple’s brand new wellness data center, HealthKit, asks you a few basic questions, and then crunches some numbers to tell you how long you’ll live.

It’s not meant to be some spoOoOoky Grim Reaper-esque invention, but rather “a way to motivate yourself to be healthier, and consult a physician as necessary.”

It works like this: When you open the app, it’ll ask for permission to access a list of biometrics: your sex, birthday, different types of blood pressure, height, quality of sleep, activity, and weight. These are all metrics that your iPhone’s Health app can track changes in, either through sensors in the iPhone, or through gadgets that can connect to your i-device.

This way the app can update your time of death depending on any new information HealthKit gathers as you go about your daily life.

After that, it’ll ask you a few questions about how much you drink and smoke and drive in cars and stress out.

Then Deadline will use whatever magical algorithm it has come up with to estimate how much longer you have to live, along with a countdown dashboard.

Of course, that number isn’t set in stone. There are all sorts of fun things like freak accidents and Ebola to keep death near and dear. But if all else goes well, I am going to live till I’m 77, according to Deadline, and I am perfectly fine with that. How cool would the latest iPhone be by then anyway?
