How your habits compare to averages

Daily screen time -
Phone checks/hour -
Daily notifications -

Global averages: 6.5h screen time, 8 checks/hour, 96 notifications/day. Sources: DataReportal 2025; Asurion 2024.

Each notification costs 23 min of focus recovery (Gloria Mark, UC Irvine, 2023). Pre-sleep screens delay melatonin by 30-60 min (Harvard Medical School, 2024).
