How the questions, the morning and evening check-ins and your week fit into an ordinary day.
Why Life Clock exists
Health advice talks in decades and percentages. “Raises your risk by 17%” is true, but nobody feels it. Everyone understands time.
A cigarette costs about 20 minutes. A brisk walk buys some of them back. When the price shows up today, the choice changes today.
What it does. Life Clock starts from the official life table for someone of your age, sex and country. Then it moves the clock with your real habits: smoking, alcohol, movement, sleep, food, mood, the people around you, your heart and blood sugar. Twice a day, a few taps turn the day you just lived into minutes gained or lost.
Why we built it. Most of the years people lose come from small, daily choices that feel free in the moment. We wanted to put a fair, visible price on each of them, so that doing the right thing becomes a reward you can see, not a lecture you ignore.
The ancient Greeks had two words for time.
Life Clock shows you Chronos so you can live in Kairos. That’s why the voice of the app is called Kairos. The Stoics kept a similar idea, memento mori: remembering that time is limited, not to be afraid, but to spend it on what matters.
- Truth, told kindly. Honest numbers without shame or scare tactics. Kairos can be strict, never cruel.
- Science, not hype. Every effect comes from peer-reviewed research and links to its source. Estimates are labelled as estimates.
- Small days, big years. You can’t change a decade tonight. You can change today, and the days add up.
- Better together. Habits stick when someone is in it with you. That’s why Lifeline exists.
- Your data is yours. Your answers stay private. A Lifeline partner sees only whether you closed your day.
Your clock moves every day
The average is where you start. Your habits decide where you go from there, and Life Clock shows it in minutes, not lectures.
A short, specific questionnaire
Age, body, smoking, alcohol, movement, sleep, food, mood, people, heart and blood sugar. Your personal clock appears at the end.
Morning and evening check-ins
Tap a few answers. Each habit adds or removes minutes, based on how much a day like this, every day, would change your years.
Kairos and your Weekly Wrapped
Kairos, your clock’s calm, sometimes strict voice, tells you what each day was worth. On Sunday you get a 9:16 story of your week to share.
Example values for a 36-year-old man in the US. Your clock computes your own.
Lifeline: link your clock with someone you love
For 21 days you each keep one promise. Your rings turn together, you can send a heartbeat when they need it, and the time you buy back together grows only on the days you both keep it.
They see whether you closed your day and the minutes you earned. Never your answers.
Learn
One 30-second science question a day, with the study behind it.
Check-ups
Which screenings are due for your age and sex, based on the US Preventive Services Task Force.
Calculators
Daily calories, protein, waist-to-height ratio and metabolic age, all from the same answers.
Science first. No guesswork.
Your starting point is a life table calibrated to your country’s official life expectancy. Each habit moves it by its effect size from large, peer-reviewed studies, adjusted so nothing is counted twice. Every number links to its source.
- Jha et al., NEJM 2013 · smoking
- Arem et al., JAMA Internal Medicine 2015 · physical activity
- Global BMI Mortality Collaboration, Lancet 2016 · body weight
- Wood et al., Lancet 2018 · alcohol
Facts, not guesses
Every number in Life Clock comes from published, checked sources, never from random blogs or one small study:
- Official life tables from national statistics offices in 14 countries, including NCHS/CDC (US), Eurostat, ONS, StatCan, ABS and MHLW.
- Large peer-reviewed studies in leading medical journals such as NEJM, JAMA, The Lancet, BMJ and Circulation, many following hundreds of thousands of people for years.
- Guidance from major health organizations and expert panels: the World Health Organization, the American Heart Association, the CDC and the US Preventive Services Task Force.
Where the science is less certain, the number is labelled as an estimate.
A framework, not a forecast
These figures describe large groups of people, not you personally. Your genes, medical history, treatment and plain luck make every body different, so no app can tell you exactly how long you will live.
Life Clock is a framework: an honest picture of how everyday habits tend to add or take away time. It is built to give you clarity and a sense of responsibility, and to make looking after yourself simple, visible and even fun, one day at a time.
For motivation and education only. Life Clock is not a medical device and does not replace your doctor.
