What does the death clock app do?

• Estimates your age at death and projected death date from your birth date, sex, country and BMI.
• Shows a live countdown in years, months, days, hours, minutes and seconds.
• Shows the middle half range and your survival curve.
• Lists the changes that would add the most years for you.
• Lets you save a result image or share a link.
• Includes the death date calculator, the age at death calculator, the death countdown and the quiz, once you have opened them.

Is the death clock app private?

Yes. The app runs the calculation on your phone. Your birth date, weight and answers are never sent to us or stored on a server. Once installed, the calculator also works with no internet connection. If you use it on a shared device, press “Start over” when you are done.

How is this different from other death clock apps?

We can only speak for ours. It uses UN life tables and published studies, and it shows every constant and source on our method page. It gives a range next to every estimate, and it never asks for an email, a payment or access to your contacts, photos or location. If you use another app, it’s worth checking what data it collects and where its numbers come from.

Why a web app and not an app store download?

• No cost, no subscription. We don’t charge for anything.
• No account. Nothing to sign up for, nothing to forget.
• Small and fast. It takes up very little space.
• Always up to date. When new UN or WHO data comes out, the app updates on its own.
