StillfeedScreen-time life clock: how much of what's left goes to your phone
This isn't a medical prediction of when you'll die — it's a rough, average-based estimate, built to show what your current screen-time habit adds up to over however much time is left. Enter your age and daily phone/social time below.
This is an estimate from population averages, not a prediction about you. It doesn't know your health, habits or family history. If you're looking for an actual demographic estimate, see the Social Security Administration's own life expectancy calculator.

How the estimate works
Your "years left" starts from life expectancy at birth in the CDC's most recent US data — 78.4 years overall, 75.8 for men and 81.1 for women (National Center for Health Statistics, Mortality in the United States, 2023) — minus your current age. That's a simplification: real actuarial tables give people who've already reached a given age more remaining years than this subtraction does, because they've already survived the mortality risk of the years before it. This page doesn't apply that adjustment, so treat the "years left" number as a rough, slightly conservative average, not an actuarial one. If the subtraction goes to zero or below (you're already past the average), it floors at 1 year so the calculator still has something to show.
From there: your daily minutes × the days in a year × your remaining years gives the lifetime total, shown in hours, waking years (at 16 waking hours a day, the same assumption the doomscrolling calculator uses) and as a share of your estimated years left.
Why a "life clock" for screen time?
People search for death clocks and life-expectancy calculators to put a number on time, and most of them get a single answer and move on. This page asks the same question a different way: of the years an average life-expectancy estimate gives you, how many would your current phone habit actually use up? The CDC can tell you the average years; only your own Screen Time data can tell you the real daily number — see average screen time by age for how your number compares to others.
Keeping more of it
The honest version of "cutting down" usually isn't willpower, it's changing what loads when you open the app:
- Remove the endless feeds, keep the app. Stillfeed is a free iPhone browser for Instagram and YouTube that removes Reels, Shorts and Explore before they load, and works with X, Reddit, TikTok, Snapchat and LinkedIn too.
- Add a stopping point — a daily limit that puts back the "do I want more?" moment an endless feed removes.
- Check your actual number, not a guess. Take the phone addiction test or try the screen time calculator for the books, films and money a cut would win back.

Common questions
Is this a real life expectancy calculator?
No. It's a screen-time tool that borrows the "years left" framing from life-expectancy calculators to make a point about scrolling, using one public average (CDC life expectancy at birth) as a rough starting point. A real estimate would also need your health, family history, habits and country, and even then it's an average, not a prediction for you specifically. For an actual demographic estimate, the Social Security Administration's own life expectancy calculator is a better starting point, and neither tool replaces medical advice.
Why does it ask for sex?
Life expectancy at birth differs by sex in US population data: about 75.8 years for men and 81.1 for women versus 78.4 overall (CDC/NCHS, 2023). It's optional; leave it on "Average" if you'd rather not say.
How is "years to the feed" calculated?
Your daily phone/social minutes are multiplied by the days in each remaining year, then added up across your estimated remaining years. It assumes your current habit stays exactly the same, which real habits rarely do — it's a "what if this continues" number, not a forecast.
Is my data stored?
No. Everything is calculated in your browser. Nothing you enter is sent anywhere; your numbers only appear in the page address so you can share or bookmark your result.
How is this different from the screen time calculator?
The doomscrolling calculator projects your scrolling to a fixed age (80) and shows books, films and money you'd win back by cutting down. This page instead starts from an actual population life-expectancy average for your estimated years left, and focuses on the share of those years the feed would take rather than what cutting down gives back.
