Ten minutes a day is four months of your life.
Kept counts the exact weeks and days between today and the date you name, shows where they currently go, and prices one small daily trade in the life it gives back. Your dates, your number. No averages.
2,817 weeks and 5 days
Each cell is one month of your life. Born 28 July 2000, horizon 80 — so on 28 July 2026 that is the exact count to 28 July 2080, not an estimate. Yours is computed from your own dates, on the day you look.
If this stirs up real distress, that is a conversation for a person you trust, not something to click through.
The problem
“Where did the last decade go?”
You can feel time moving faster and you cannot point at where it went. The years are a blur and the evenings are a habit.
“I know my screen time is bad. Knowing hasn’t changed it.”
Your phone tells you the number every Sunday. It has never once changed a Tuesday. Awareness is not the missing piece.
“I’ll deal with it later.”
Later is the whole problem. Nothing about an evening on the couch costs anything you can see, so the cheap choice wins, one evening at a time, for thirty years.
How it works
See what’s left.
Two fields: your birth date and a horizon age you choose. Kept turns them into a date — born 28 July 2000, horizon 80, gives 28 July 2080 — and counts the exact days between then and today. Your life renders as a grid of months, one row per year, grouped by decade, the lived ones dimmed. Takes about two minutes and no account.
Each square is one month of your life.
Describe a day, and your year.
One typical weekday, one typical weekend, as blocks across 24 hours: sleep, work, people, the scrolling. Each day fills exactly 24 hours, with everything else absorbing the remainder, so nothing hides in the gaps. Then one number: days off a year. Those come out of your working days, not on top of them. Counting them the other way invents work that never happens: 30 days off at 8 hours is 240 phantom hours a year, about 13% more than the year really holds.
Weekday template — 24 hours, no gaps. Sleep, commute, work, people, scrolling.
Trade ten minutes.
Take ten minutes from something draining, give it to something you’d rather have. Kept prices that trade in years, months and days of your own life — computed from your dates, not an average — and lights up the months it buys back on your own grid. Tap once a day when you hold it. What you’ve banked only ever goes up.
4 months, 13 days
if you hold it — on 28 July 2026, 19,724 days × 10 minutes, counted across the real dates in between.
Zoom, any time. Your whole life, a year, a month with its real dates and weekends, a week, a single day. Change a block in your Tuesday and watch the months move on your life. Days you already lived stay blank — Kept was not there, and it will not invent them.
Works inside Claude
Ask Claude to log it.
Kept is built to connect to Claude, so you will be able to log today’s trade, check your reclaimed total or adjust where your week goes in a conversation, without opening the app — and see exactly which actions Claude may take before you approve. The connector is not live yet; it ships with the app.
- Read your grid, your day templates and your reclaimed total
- Write today’s hold and changes to your trades
- Account your horizon and settings
A 60-second walkthrough replaces this panel once the connector is live.
What people say
Kept is new. When people have used it long enough to have something true to say, their words go here.
Questions
Isn’t this morbid?
It is arithmetic, not a memento mori. There is no countdown, nothing ticks, nothing turns red. Most people describe the grid as clarifying rather than frightening. If it isn’t for you, close the tab — that is a reasonable response and the app will not chase you.
Where does the horizon number come from?
You pick it. Kept does not estimate anyone’s lifespan, does not ask about your health, and has no actuarial model. The horizon is labelled as an assumption you chose everywhere it appears, because that is what it is.
Ten minutes a day really gives back four months?
For someone born on 28 July 2000 expecting to see 80, asking on 28 July 2026: ten minutes a day across the 19,724 days they have left is 197,240 minutes, which is 4 months and 13 days. Every figure on this page is that one person on that one day — yours comes from your own dates, on the day you look. No averages, no rounded years. It also means the reverse is true, which is the uncomfortable part.
Do you track my screen time?
No. No device access, no OS integration, no always-on agent. You type the numbers yourself. Self-reported screen time runs low — your phone’s own report is worth checking, and we say so in the app.
What happens to my data?
It is a birth date and private notes about your own life. It is never sold, never advertised against, never shared. You can export everything as plain text and delete the account and all its data from settings, in one screen, without emailing anyone.
