The app, called Deadline, uses iphone's Healthkit to "determine your date of expiration."

Healthkit tool records statistical information, like the user's height and diastolic blood pressure, and monitors their sleep and the amount of steps they take in a day.

Using this data and a short survey with more questions about their lifestyle, the app determines the approximate date and time of a person's demise, and then counts down how much time they have left, '' reported.

The app's developers Gist LLC pointed out in the product's description, "no app can really accurately determine when you will die."

Instead, the company suggests using the app as a way to monitor your own health and motivate yourself to make better lifestyle choices or consult a physician, if necessary.

Users can change their predicted date of death by following a healthy diet and an active exercise routine.
