📵 Phone Reality Check
"4 hours a day" hides the truth. This converts your screen time into the only units that matter — years of your life, kilometres of scrolling, and what you'd get back by keeping one hour a day for yourself. No data leaves this page; iOS and Android both show your daily average in settings.
at this rate, the rest of your life on the phone is
8.3 years
— 28% of every waking day for the next 44 years
118 km
scrolled per year — thumb travel
15 days
recovered per year if you keep 1h/day
1.8 years
returned over your remaining life
61 books
readable per year with that 1 hour
One hour a day is enough to reach conversational level in 40 foreign languages before you turn 72.
~400 focused hours gets a language to conversational — that's all this means.
The maths: your daily minutes × days remaining, waking share vs 16 waking hours, ~1.2 m/min average thumb scroll, 360h per book, 400h per conversational language. It's arithmetic, not therapy — if the numbers annoy you, that's the tool working.
Frequently asked questions
You enter your daily screen time and it converts it into units that actually land: days per year, years of your life at your age, kilometres of thumb-scrolling, and what you'd get back by shaving off an hour a day — in books read, languages learned or gym sessions.
