Screen Time / Digital Detox Value Calculator
What that time could be instead
Why this might be worth a break
In a 2024 University of Texas at Austin / University of Oregon study, 467 volunteers who blocked internet access on their phones for two weeks — 91% reported feeling better on at least one measure of well-being, mental health, or attention span, with the sustained-attention improvement comparable to reversing roughly a decade of age-related decline. These are reported outcomes from that specific trial, not a guarantee for everyone — but they're a real, measured result, not marketing copy.
These comparisons use fixed, disclosed assumptions to make the math relatable, not to shock — swap in your own numbers if you read faster, sleep less, or fly a different amount. This is general information, not a promise of specific results.
Free screen time calculator with disclosed, honest equivalents (not inflated marketing numbers) — see your annual screen time in hours, days, books, sleep, and flights, plus real cited digital-detox research. No app download or signup required.
How it works
- Enter your average daily screen time
- See it converted to annual hours and full 24-hour days
- See it reframed as books read, nights of sleep, or round-trip flights — using disclosed, fixed per-unit hour assumptions, not gimmicky inflated numbers
Frequently asked questions
Where do the "6 hours per book" and other comparison numbers come from?
6 hours per book assumes a typical ~90,000-word novel read at roughly 250 words per minute, a commonly cited average adult silent-reading speed. A full night of sleep is 8 hours, and a round-trip long-haul flight (like New York to London and back) is roughly 14 hours. These are disclosed, fixed assumptions meant to make the number relatable, not to maximize shock value — your own reading speed, sleep needs, or flights will differ.
Does taking a break from screens actually help?
In a 2024 University of Texas at Austin / University of Oregon study, 467 volunteers who blocked internet access on their phones for two weeks — 91% reported improvement on at least one measure of well-being, mental health, or sustained attention, with the attention-span gain comparable to reversing roughly a decade of age-related decline. That's a specific study's reported result, not a guarantee for every person.
Do I need to download an app or sign up to use this?
No — this is a standalone calculator, not a funnel toward an app download or a multi-step quiz requiring an email address, unlike some other screen-time tools.
