How to check screen time on iPhone
Your iPhone already tracks a daily average, weekly trend and per-app breakdown. Here is where to find it and which number to use in the calculator.
Go to Settings → Screen Time → See All App & Website Activity. Toggle Day/Week to find a typical average. The breakdown by app is on the same screen.
Use the screen time calculatorOne day can be misleading — travel, a long call, or a weekend binge can skew it. The Week view smooths those outliers.
Use the daily average shown at the top for Week. That is the most useful input for the calculator and for the days view.
The total tells you how much, the breakdown tells you where. Compare the apps you intentionally use with those you open without planning.
That split helps you choose one realistic next step instead of a broad ‘use phone less’ goal.
