Time Wasted on Phone
Enter your current age, daily screen time and a life-expectancy assumption, and this tool runs real arithmetic — daily hours ÷ 24, multiplied by years already lived and years remaining — to show years already spent on your phone and a straight-line lifetime projection if your habits don't change.
The result is a big shareable card showing the total lifetime years, with the math kept fully auditable in the breakdown above it.
Key features
Real, auditable arithmetic
Years already spent, years projected, and lifetime total, each shown separately.

Private
All math runs locally, no data leaves your browser.
How to use it
- Enter your current age.
- Enter your daily screen time in hours.
- Adjust the life-expectancy assumption if you want.
- See years already spent and the lifetime projection.
Worked example
Example
Age 27, 5 hours/day, life expectancy 80 → about 5.6 years already spent and roughly 11 more years projected if that habit continues, for a lifetime total near 17 years.

A shareable, honestly calculated stat.
Tips for the best results
- Use your real average, not your best day, for an honest number.
- Recalculate after making changes to see the projection shift.
- Remember the projection assumes today's habit stays constant — it isn't a prophecy, just a straight-line estimate.
Common mistakes to avoid
- Confusing the 'already spent' and 'projected' numbers — they're shown separately for a reason.
- Using an unrealistic life-expectancy assumption that skews the projection.

Frequently asked questions
Is this exact?
It's exact arithmetic given your entered averages; real daily variation means your true total may differ.
What does 'projected' mean here?
A straight-line estimate assuming your current daily screen time continues unchanged until your life-expectancy assumption.
Can I change the life expectancy assumption?
Yes, there's a dedicated input for it so you can model different scenarios.
Is my data stored?
No, everything is calculated locally in your browser.
Does this count all phone use or just certain apps?
It uses whatever daily screen-time figure you enter, however you choose to define it.
Can I share this result?
Yes, using the Share or Save image buttons on the result card.
