Screen time by age calculator
A daily average looks different beside the years ahead. Enter your age and daily screen time for a simple, private estimate — then choose one habit to test.
Klippy multiplies your daily average by the years from your current age to 75. It counts every hour equally, so treat it as an awareness starting point, not a score.
Use the screen time calculatorThe same daily habit has more time to repeat when you are younger. Seeing the total to 75 makes an abstract routine concrete without needing to make it alarming.
Once you see the total, you can ask a narrower question: is there one app, time of day, or cue that creates most of the automatic time? A small boundary there is easier to keep than a broad limit.
The calculator does not know which hours are for work, family, learning or unwinding. Use the number to separate the phone use you value from the checks that happen without a clear reason.
If the result surprises you, start with the least intentional time. Keep the useful parts of your phone and add friction only where the automatic check starts. See also: screen time in full days and how to find your average on iPhone.
A practical next step
Open Settings → Screen Time → See All Activity and use a typical daily number.
Used only for the estimate to 75. Nothing is saved.
Pick one app or moment that feels automatic, not everything at once.
No. It is simple math from the daily number you enter, multiplied by the years to 75. Use it for awareness, not as a precise forecast.
No. The tool runs in your browser and never connects to your iPhone.
Test one boundary for a week — for example, no social feed in bed, or quieter notifications during work — and keep what helps.
