Every 20 minutes, look 20 feet (≈6 m) away for 20 seconds. This is the single most evidence-backed move against digital eye strain — recommended by the American Optometric Association.
- No formal cap, but every 20 min look 20 ft away for 20 seconds — the single best move against digital eye strain.
- No screens in bed: blue + engagement is a worse combo for sleep onset than caffeine.
- If you cross 8 h/day total, that's heavy — consider an evening cap and one full screen-free day per week.

What this tool does
Free screen-time budget tool. Add the hours you spent today on each device — phone, tablet, PC/laptop, TV, game console — pick an age band, and the page tells you (1) the total, (2) where that total falls against the WHO and AAP age-based caps, (3) the per-device share as a self-rendered SVG donut so the page weighs almost nothing, (4) an eye-strain risk band, and (5) age-targeted tips backed by the WHO under-5 guideline and the American Academy of Pediatrics. The reference caps in the UI are: under 2 — none (video calls excepted); 2–5 yr — ≤ 1 h of high-quality co-viewed content; 6–17 yr — ≤ 2 h recreational; adults — ≤ 4 h non-work as a soft target with the 20-20-20 rule (every 20 min, look 20 ft away for 20 seconds) recommended for any work-hour block. Save today's number to a 7-day browser-local history to see the trend — single days don't tell you much, the trend does. Nothing is uploaded; everything is computed in your browser and stored in localStorage only. Built for parents who keep googling "is X hours too much for a Y-year-old" and for adults who want a cross-device total that iOS Screen Time and Android Digital Wellbeing don't give them.

Real-world use cases
A parent settles the nightly iPad argument with one household number
Your 7-year-old swears she "only used the iPad a little." Add it up here: 35 min iPad, 50 min phone games, 1 h of console TV. That's 2 h 25 min, well over the AAP 2 h recreational cap. Show her the donut: the console TV is 41% of the day, not the iPad she's defending. Now the conversation is about the biggest slice, not a vague "too much."
A desk worker checks whether 8 work hours plus evening scrolling is the real problem
You log 8 h work screen, 1.5 h evening phone, 1 h TV. The tool flags that work dominates and your non-work total is 2.5 h, under the 4 h soft target. So the fix isn't "cut Netflix"; it's the 20-20-20 rule across the work block and no phone in bed. The number tells you where cutting actually moves the needle.
Tracking a kid's screen trend across a school week, not a single day
One Saturday at 4 hours looks alarming. Save 7 days and the history shows Mon-Fri averaging 1 h 10 min, with weekends spiking. That pattern is normal and fine; a single panic-day is noise. The 7-day local history turns "did we blow it today" into "is the week trending up," which is the question that actually matters.
Comparing two devices when iOS Screen Time only shows one
iOS Screen Time reports 30 min on the iPad and you feel reassured, but the kid also had 45 min on a sibling's phone and 40 min on the Switch. Enter all three and the cross-device total is 1 h 55 min, right at the AAP line. The OS tools each tell the truth about their own device; this tool gives you the one number none of them can.
Common pitfalls
Counting school work and video calls as recreational screen time. A kid doing 1 h of math homework on a Chromebook is not "1 h over the AAP cap." Enter recreational use only, or the number scares you for no reason.
Judging a single day instead of the trend. One 4-hour rainy Sunday means nothing alone. Save 7 days first; a Tuesday-to-Tuesday average is the honest signal, not yesterday's spike.
Logging only the phone and forgetting the TV and console. The whole point is the cross-device total. If you skip the 90-min console session, you've recreated the exact iOS blind spot this tool exists to fix.
Privacy
Everything stays on your device. The hours you type for each device and the age band you pick are never sent to a server, and they are not put into the URL either, so a shared link carries no one's actual screen numbers. The optional 7-day history lives only in this browser's localStorage and is visible only to you on this device; clearing browser data wipes it. No sign-up, no tracking cookies, no analytics on your entered hours.
