Yorick app icon, a golden hourglass drawn as a constellation Death Clock & Lifespan

Death clock and life expectancy calculator for iPhone

Nineteen questions, one estimated date built from actuarial life tables, and a named study behind every single number that moved it.

Download Yorick on the App Store

Free download. Your full result and date cost nothing.

Yorick is a free iPhone app that estimates your statistical life expectancy from 19 lifestyle questions, using the US Social Security Administration 2022 period life table and United Nations mortality data covering 234 countries and territories. Your estimated date, your age at death and the likely range around it are free. A one-time $4.99 Pro purchase adds the what-if levers and removes ads. The estimate is calculated on your iPhone.

What you actually get

The result first, the sales pitch never.

Most lifespan apps blur your date until you subscribe. Yorick shows it, then leaves you to decide whether the rest is worth one payment.

Four things it does

Built like an actuary would build it.

An estimated date, and the range around it

You get a date, an age, and an honest likely range. The range is never narrower than three years and grows with the amount of life you have left, because pretending to be precise about 2065 would be a lie.

Nineteen questions, nineteen citations

Smoking, alcohol, weight, diet, movement, strength, sitting, sleep length, sleep regularity, diagnoses, family, connection, stress, work, education, supplements. Tap any factor to open the study on PubMed.

Your life in weeks, as a constellation

Every week you have lived is a lit star, every week left is a dark one, and a live counter ticks down the days, hours, minutes and seconds. Memento mori with a real number behind it.

Eleven levers you can pull

Change one habit and the whole model runs again, so the years you gain are correct for your age and your other answers. One lever is free to try before you decide about Pro.

How the number is made

Actuarial tables, not an algorithm that guesses.

Yorick begins with the US Social Security Administration period life table for 2022, which gives remaining life expectancy for every single year of age and both sexes. That table alone says a newborn boy reaches 74.7 and a newborn girl 80.2.

Your country then shifts the level. Yorick carries United Nations World Population Prospects 2024 figures for 234 countries and territories, and the shift fades as you age, because someone who already reached 70 has outlived most of the gap.

Only then do your answers move the number, using effect sizes from named studies. Related answers sit in one group so the same risk is never counted twice, the total is compressed toward a hard ceiling of 18 years, and the whole adjustment shrinks as you get older.

Where the numbers come from

  • SSA Period Life Table 2022, baseline mortality by age and sex
  • UN World Population Prospects 2024, 234 countries and territories
  • Doll et al., BMJ 2004 and Jha et al., NEJM 2013, smoking
  • Fadnes et al., PLoS Medicine 2022, dietary pattern
  • Moore et al., PLoS Medicine 2012, physical activity
  • Holt-Lunstad et al., PLoS Medicine 2010, social connection
  • Windred et al., Sleep 2024, sleep regularity
  • Li et al., Circulation 2018, calibration of the combined effect
  • Manson et al., NEJM 2019, the VITAL supplement trial
The supplement answer is worth zero, on purpose. The VITAL trial found no mortality benefit for vitamin D or omega 3, so Yorick counts the question at zero years and says so on the screen. An app that wanted to flatter you would have found a way to award points.

Free and Pro

One payment of $4.99, or nothing at all.

Yorick Pro is a single non-consumable purchase, not a subscription. It is tied to your Apple ID, so a new iPhone restores it.

About the ads. The free version is paid for by Google AdMob, which asks for your advertising consent choices the first time you open the app. The interstitial is deliberately rare: it can appear only from your second session onward, and never twice within three minutes. Pro removes both. Your quiz answers stay in the app's own folder on your iPhone either way, and the estimate itself is calculated there.

Questions and answers

Frequently asked questions

Is Yorick free?

Yorick is free to download and your full result costs nothing. Your estimated date, your estimated age at death and the likely range are shown in full, with nothing blurred or held back. Yorick Pro is one optional purchase of $4.99. There is no subscription and no recurring charge.

How does Yorick calculate life expectancy?

Yorick starts from the US Social Security Administration period life table for 2022, then shifts that baseline to your country using United Nations World Population Prospects 2024 figures for 234 countries and territories. Your 19 answers then move the result using effect sizes taken from named studies. Correlated answers are grouped so the same risk is not counted twice, the total is damped toward a hard cap of 18 years, and the whole adjustment shrinks with age. The method is calibrated against Li et al., Circulation 2018.

How accurate is a death date calculator?

It is a statistical estimate for people who answered the way you did, not a forecast for you personally. Yorick makes that explicit: every result carries a likely range, at least three years wide and wider the more life you have left, and no estimate goes past age 105. Every factor names the study it came from, so you can check the reasoning instead of trusting a black box.

Does Yorick send my answers anywhere?

No. There is no account and no sign up, the mortality tables ship inside the app, and your estimate is calculated on your iPhone. Your answers are stored in the app's own folder on the device and are deleted when you delete the app. The free version is supported by ads, which are served by Google AdMob and ask for your consent choices when you first open the app. Yorick Pro removes the ads.

What does Yorick Pro add?

Pro unlocks all eleven what-if levers with the years each one is worth and the study behind it, the Lab where you stack several changes and ask what it would take to reach a chosen age, the breakdown that shows which factors cost you the most, the country comparison, and your best possible date. It also removes the ads. It costs $4.99 once, is tied to your Apple ID and restores on a new iPhone.

Which iPhone do I need?

Yorick runs on iPhone with iOS 26.0 or later. The download is about 5.8 MB because the mortality tables and every cited effect size are bundled inside the app rather than fetched from a server.

Is Yorick medical advice?

No. Yorick provides statistical estimates for educational and motivational purposes only. It is not medical advice, diagnosis, or treatment. Consult a qualified healthcare professional before making any health decisions based on your result.
