Iris applies dark mode and a warm evening glow to any site, nudges you to rest your eyes on a schedule, and tracks your screen time — all calculated and stored locally in your browser.

until your next eye break
Iris runs quietly in the background and only steps in when it's actually useful.
Inverts any page you're on — always on, always off, on a schedule, or matched to your system theme.
A gentle amber glow that eases in gradually after sunset, instead of snapping on all at once.
Follows the 20-20-20 rule by default, plus separate blink reminders — both fully adjustable.
See active time, top sites, and streaks for the last 30 days — calculated and stored only on your device.
Exclude the odd site that already looks better in light mode, or restrict Iris to just a chosen few.
English, Spanish, French, German, Portuguese, and Hindi — matched to your browser or set manually.
Choose always-on dark mode, a schedule, or "match my system theme" — whatever fits how you actually browse.
Pick a start and end time, an intensity, and how gradually it should ease in — Iris handles the rest.
A quiet notification when it's time for a 20-second break, with your streak and stats tracked in the popup.
Add sites to skip, change your language, export your history to CSV, or reset your stats — all in Settings.
Free, no account, nothing leaves your browser.
