Opsin now works anywhere on Earth. • Weather and UV wherever you are. Outside the US, Opsin now uses Apple Weather for live conditions and UV, so your vitamin D window and sun guidance stay accurate abroad. • Travel-aware. Land in a new time zone and Opsin retimes your sun windows, alarms, and meal window automatically. • Built for extreme latitudes. Under the midnight sun or in polar night, Opsin switches to honest, clock-anchored guidance instead of going blank. • Stability and accuracy improvements.

What's New: Fixes a crash when opening the app from a notification.

Your first 90 seconds, rebuilt — and proof you can see. - A new first run: allow location, see your real sunrise and today's light windows immediately, and arm your dawn alarm before anything else. - Watch the setup video — Screen Shield (blue light filter) now walks you through it on video, plus a guided setup for the Light Windows Lock Screen widget. - Lock Screen widget now counts down in clean minutes. - Haptics throughout — logging light, closing your eating window, scrubbing the UV chart. - Fixes and polish under the hood.

Your day, coached end to end. - Meals & Movement — eat while the sun is out. Opsin sets tonight's kitchen-closed time from your sun and bedtime, nudges you when it's time to start dinner, and logs a window closed on time. - Next Action card — Today now leads with the one thing to do right now: morning light, afternoon sun, dinner, wind-down. And it knows when you've already done it. - Lock Screen, alive — Live Activities count down your current light window, and the new Light Windows widget keeps the next one on your Lock Screen without ever opening the app. - UV, reborn — the chart now runs sunrise to sunset. Scrub it hour by hour; your vitamin D window is marked on the curve. - Weekly recap — Sunday evening: your week in light, and what it did for your sleep. - Plus: movement prompts, Screen Shield setup guide, a refreshed intro, and a daylight-saving alarm fix.

Opsin now runs on iPhones with iOS 18 and later — welcome to everyone who couldn't join us at launch. • A new introduction that shows you what Opsin does and why your body clock matters • Jet-lag plans rebuilt on the Eastman/Burgess light protocol — realistic shift rates, a progress ring that tracks how far you've re-timed, and an optional plan for the trip home • Guidance for setting up an evening red screen filter • Daily verses refined throughout True Alarm still requires iOS 26.
