Conversions use round figures for illustration. They are here to change the unit, not to be precise.
This calculator turns your daily screen time into hours per week, days per year and months over a decade. Enter the figure your phone already shows you.
- You enter: Your daily screen time, in hours.
- You get: Hours per week, days per year and months over a decade.
- Cost: Free, instant, no sign-up.
The hours are real. The next one doesn't have to be.
Offimo puts a few seconds between the urge and the app, so the quick look stays quick.
Screen time reports give you a daily average, and a daily average is the one unit that makes the number feel fine. Four hours is an evening. Sixty-one days is a season of your life, and it is the same fact.
That is the entire trick of this calculator: it does no research and knows nothing about you. It takes the figure your phone already shows you and moves the decimal point into a unit you can feel.
Where to find your real number
On iPhone: Settings → Screen Time → See All App & Website Activity. Use the weekly average rather than today's total; a single day is noise.
Most people's honest number is higher than their guess, and the gap itself is worth noticing. If you had to estimate before checking, the size of the error tells you how much of that time is invisible to you while it is happening.
Why the yearly figure changes the decision
A daily average invites a daily response: try harder tomorrow, be more disciplined tonight. That response fails on volume, because the decision comes back fifty times a day and you only have to lose once.
The yearly figure invites a structural response instead: change the setup, not the willpower. That is a decision you make once, calmly, and it holds while you are tired, bored, or already three swipes in.
What a realistic reduction looks like
Cutting a four-hour habit to zero is not a plan, it is a mood. Cutting it by an hour is arithmetic: that hour is fifteen days a year back, and it survives contact with a bad week.
Run the calculator twice: once with your real number, once with your real number minus one hour. The gap between the two results is what is actually on the table.
Frequently asked questions
Where does the data go?
Nowhere. The whole calculation happens in your browser and nothing is sent or stored. Close the tab and it is gone.
Is the yearly figure accurate?
It is exact arithmetic on the number you typed: hours × 365, divided into days. Whether it describes your year depends entirely on whether your daily average is honest.
Why compare against 16 waking hours?
Because comparing screen time to a 24-hour day quietly counts the time you were asleep as time you could have used. Sixteen hours is the closer approximation of a day you are actually available for.
What do I do with the number?
Pick one hour of it. Then change something structural about how that hour starts, which is the problem Offimo exists to solve, by putting a pause between the impulse and the app.
