What your screen time actually adds up to
Type the daily average your phone already shows you. The first calculator turns it into days of the year; the second turns it into the hours between today and a date you choose. Both work out your number, not a stranger's.
Your daily average, as days
Hours a day multiplied by 365, divided by 24. That is the whole calculation, and it is worth seeing drawn out: each square below is one day of the year, and the coloured ones are the days your phone would account for at your current rate.
Read your daily average from Screen Time on iOS or Digital Wellbeing on Android. Each square is one day of the year. Nothing you type here is stored or sent anywhere.
Your hours between now and the exam
Set the date of the exam — or the interview, or the submission — and the same rate turns into the hours it will take out of your preparation. This is the version most people find harder to argue with, because the deadline is real and the total is theirs.
Your daily average is in Screen Time on an iPhone, or Digital Wellbeing on Android. The dates come from your own device’s clock. Nothing you type here is stored or sent anywhere.
What an average Indian user does
An Indian smartphone user spent an average of 4.95 hours a day in apps in 2024, measured by Sensor Tower and published by FICCI and EY. Across the country that came to 1.23 trillion hours in 2025, up 9% on the year before.
Treat that as a ruler, not a verdict. It is an average across users, it counts time in apps rather than time wasted, and being below it proves nothing about your afternoon. Your own number in the box above is the one that matters.

What these two numbers do not mean
- Screen time is not wasted time. Lectures, maps, the call with your parents and the alarm clock all land in the same total. The figure worth acting on is the part you would not have chosen, which no counter can separate for you.
- An average is not a day. Most people have a four-hour Sunday and a forty-minute Tuesday. The calculator assumes today repeats, which is a projection, not a prediction.
- Cutting it to zero is not the goal. The useful question is not how low the number goes but whether you chose it — and the honest test of that is whether you can put the phone down when you decide to, not what the counter says on Sunday night.
