Screen-Time vs Lived-Time
The clock counts both the same. Your life doesn't. Phone shows you spent four hours on it; how many hours did you actually live? The gap is your receiving deficit.
Use your phone's Screen Time / Digital Wellbeing data for the screen number. Estimate the lived number honestly — you'll know it when you remember it.
The two flavours of "life"
Watching a beautiful film with attention is reception. Scrolling an algorithmic feed for the same duration is consumption. The clock can't tell them apart. You can.
This isn't a moral judgement on screens — your phone is also where you call your mother, where you read this site, where you find a recipe. The audit is about passive screen time only — the kind that leaves nothing.
