Screen Time Calculator
Turn daily phone or app time into hours per year, days lost, workweeks, books, workouts and a simple focus-blocking plan.
What the numbers mean
Small daily habits compound. One hour a day is 365 hours a year: more than nine 40-hour workweeks, or roughly fifteen full 24-hour days.
When LockHour Pro helps
If Apple Screen Time is too easy to ignore, a dedicated focus blocker can create intentional sessions for deep work, study, workouts and sleep routines.
FAQ
How do I find my iPhone screen time?

No. Work, navigation, reading and communication can be valuable. This calculator is best for discretionary apps you want to reduce.
What reduction goal is realistic?
Start with 20–30%. For example, cut a 3-hour habit by 45–60 minutes before attempting a full digital detox.
