How many years of your life
will you spend locked in on a screen?

defrag. is a free screen-time and life-balance calculator. Not a lecture. Not a screen-time shamer. Just the math — and a plan that's yours. Built for students, parents, educators, and anyone ready to look honestly at the numbers.

Built for everyone

One calculator. Every perspective.

defrag. adapts to your age, your obligations, and your life — whether you're 12 or 52. The math changes, but the question doesn't: how much of your life is actually yours?

For Students
See how much of your life you're spending on screens — not as a guilt trip, but as a grid of months you can actually see. Then decide what you want to reclaim.
For Parents
Run the numbers alongside your teen. It's the conversation starter you've been looking for — grounded in math, not lectures.
For Educators
Use defrag. in advisory, health class, or digital citizenship lessons. The data is personal, anonymous, and research-cited.
How it works

9 steps. 5 minutes. Your number.

defrag. walks you through a guided flow — each step builds context for the next. At the end, you see exactly how your time breaks down and what you could change.
