Screen Time Reality Check
Turn a daily number into a week, a year, and the years ahead. Use the categories, or paste in the one total from your phone. Then see what giving a slice of it back would look like.
- 1. Enter the hours Seven categories, or one total from the phone report.
- 2. See the year Days, books, languages, and the years ahead.
- 3. Give a slice back A percent, a plan, and a line you can copy.
Your hours
A quarter hour is 15 minutes. On an iPhone the daily average is under Settings, Screen Time. On Android it is under Settings, Digital Wellbeing. Use whichever number you actually have.
The single daily average on the report. Categories stay filled in if you switch back.

A week is 7 days. A month is counted as 30 days. A year is counted as 365 days, so leap days are left out. Days in a year are the yearly hours divided by 24. Lifetime years are the daily hours divided by 24, multiplied by the years from your age to the life expectancy.
What a year of this could also be
Give some of it back
This does not change the hours you entered. It only shows the slice.
Move a slider and this line shows what that percent gives back.
A small plan
Add your hours and a small plan shows up here, aimed at the largest slices first.

A number you can actually use
A screen-time report is a pile of small sessions. Four hours a day does not feel like much when it arrives five minutes at a time. Spread across a year it is easier to see, and spread across the years ahead it is easier to decide what you want some of that time to be instead.
Enter the categories if you have them: social, video, games, news, messaging, work, and other. The daily total is their sum. If the phone only gave you one number, switch to that total and the picture uses it directly. Switching back keeps the categories you already set. If the categories add up to more than 24 hours, that usually means two apps were open together, or a guess ran long. The math still uses the number you entered.
The lifetime line is the same daily pace, carried forward. It is your age, a life expectancy you can change, and the hours divided by 24. It is not a prediction about your health, and it is not a claim that every one of those years would be spent this way. Move either number and the line moves with it. A month on this page is 30 days, and a year is 365, so a leap day is left out on purpose.
The comparisons are a way to feel the size of a year. A book is 8 hours. A language is 600 hours, which is a common estimate for everyday conversation in a language close to one you already speak, not a hard language and not fluency. A marathon is 80 hours of training, about a beginner plan, with race day left out. A movie is 2 hours. None of these is a dare. They are rulers.
The reclaim slider cuts a percent off the daily total and shows the hours and the days that come back. The plan starts with the three largest categories and offers one tip each. If you entered a single total, the plan asks you to name the largest slice on the phone report and apply the percent there. You can ignore every tip. The picture still stands.
Nothing here is uploaded. The optional save stays in this browser, and Clear deletes it. If you want the hours you get back to land next to sleep, the sleep cycle calculator can place a bedtime. If some of that time should become study, the study plan generator can hold a schedule. The digital footprint check is the privacy side of the same phone, and Which Tech Era Are You? is a lighter read on the habits underneath the hours.
FAQ
Does this send my hours to a server?
No. The math runs in your browser. The numbers you enter can be saved in this browser's local storage so you can come back to them. That copy never leaves the device. Clear removes it. You can confirm there is no upload in the browser network panel.
How are the week, the year, and the lifetime calculated?
A week is 7 days. A month is counted as 30 days. A year is counted as 365 days, and leap days are left out so the math stays simple. Days in a year are the yearly hours divided by 24. Lifetime years are the daily hours divided by 24, then multiplied by the years from the age you enter to the life expectancy you enter. If the expectancy is not above the age, the lifetime line is zero.
What do the books, languages, marathons, and movies assume?
They describe a year at the daily pace you entered. One book is 8 hours, about a novel read at an easy pace. One language is 600 hours, a common estimate for everyday conversation in a language close to one you already speak. A harder language takes longer. One marathon is 80 hours of training, about a 16-week beginner plan, and race day is extra. One movie is 2 hours. They are comparisons, not a promise that you would finish each one.
What does the reclaim slider do?
It shows what you would get back by cutting the daily total by that percent. It does not change the hours you entered. At 20%, a 4-hour day gives back 0.8 hours a day. The plan uses the same percent on the largest categories.
Where do the numbers live, and what does Clear do?
Only in this browser, under a local storage key for this page. Clear deletes that saved copy and resets the sliders. Clearing site data for cyberscryb.com removes it too. The page does not ask for an account, a name, or an email.
Is this a verdict on my habits?
No. It is straight math from the hours you type, plus a few comparisons with the assumptions written next to them. A big number is information you can use. It is not a grade, and the plan is a suggestion you can ignore.
