Where to find your real numbers
- Open Settings → Screen Time.
- Tap See All App & Website Activity, then Week.
- Divide each app’s weekly total by 7.
Websites are listed separately from apps, so add youtube.com’s time to the YouTube app’s if you watch in Safari.
How the numbers are worked out
45 minutes a day × 365 days is 274 hours a year. Divided by 24, that’s 11 days.
- Days are full 24 hours, so results are on the low side. In waking hours (about 16 a day), the example’s 29 days would be about 44.
- A month is a twelfth of a year.
- “In 10 years” assumes your daily time stays the same.
