Blue-light filter & flicker-free dimming for macOS
It knows when
your evening is.
EyeEase warms your screen past where Night Shift stops — following the sun where you actually live, not a countdown started at sunset. Twilight takes an hour in Quito and two in Reykjavík. So does the fade.
Signed and notarized by Apple. Download it, drag it to Applications, open it. No security warning, no right-click trick, no trip into Settings — macOS checks it with Apple and lets it run like anything else you'd install.
Updates won't find you. EyeEase never checks the network on its own — click “Check for updates” in the tray menu now and then to see if a newer build is out.
Already running 0.1.0 or 0.2.0? Quit it from the menu bar first, then drag the new one to Applications and open it from there. Delete the old copy. 0.2.0 could crash when you opened the panel from the menu bar — that's fixed here. If coming from 0.1.0, also check “launch at login”: turn it on once more if it shows as off, since 0.1.0 could show that switch as on while nothing actually started at login, and this version checks properly.
New York, in August: the evening fade takes 73 minutes. Midnight at the top.
Drag the slider, then change city. Same code, same thresholds — the fade gets longer as you go north because twilight does.
Zero blue, zero flicker
One switch. The blue channel is written as literal zeros, not merely turned down, and the built-in display's backlight is pinned at full so it never strobes — the dimming moves into software instead. An external monitor dims itself, so that half only applies to the laptop screen.
Follows your sky, not a timer
Type your city. It works out the sun's height through the day and warms as the light actually goes — 58 minutes at the equator, over two hours in Iceland. Fixed hours instead, if you'd rather.
Never touches the network
No accounts, no analytics, no update pings — not a single network call in the source, which you're welcome to go and check. Even the city list is carried inside the app, so knowing where the sun is never means telling anyone where you are.
If it helps your eyes
Free, and staying that way.
No license to buy, no pro tier, nothing to unlock — the whole thing is on GitHub under the MIT licence. If it saved you a headache and you'd like to send something back, here's where.

A Lightning address — paste it into any Lightning wallet, or scan the code. Nothing here talks to a payment processor: the address is plain text on the page and the code is drawn into the HTML, so this page still makes no network requests of its own.
