Not all screens
are equal

● Passive Mindless consumption

You watch, scroll, and absorb — but your brain isn't building anything. The algorithm picks the next dopamine hit. You don't even realise an hour has passed.

TikTok, Instagram Reels, YouTube Shorts
Binge-watching Netflix / YouTube
Infinite feed scrolling
Autoplay with no intent
Every extra hour of passive screen time reduces FSI by 8–12 points on average.
● Active Engaged creation

You choose what to make, play, or learn. Your brain is in the loop — problem-solving, deciding, building. Time is intentional, not stolen.

Coding, drawing, photo/video editing
Intentional gaming with strategy
Video calls with friends
Researching or learning new skills
Active screen use preserves and builds the same attention networks passive scrolling erodes.

Sit with this for a moment.

You didn't choose to have a 7-second attention span. The platforms you use spend billions of dollars engineering it. ScrollBye exists to name the problem, measure it, and give you the data to fight back.

"The cost of a thing is the amount of what I will call life which is required to be exchanged for it, immediately or in the long run." — Henry David Thoreau, Walden (1854)
"Deep work is the ability to focus without distraction on a cognitively demanding task. It's a skill that allows you to quickly master complicated information and produce better results." — Cal Newport, Deep Work (2016)
