Overnight is now its own alert. Turn it on for the place where you sleep and pick a level. From 9 PM to 7 AM, you'll be alerted when the nearest air monitor reads above it, so you can close windows or turn on an air purifier. The Home Screen widget has its own row at the bottom of the app with the steps to add it. Each place's alerts button is now labelled, Notifications shows which places have Overnight on, and the alert sliders name the EPA air quality categories in full. Also: turning on alerts from a place now turns that place on, the star asks before removing a favorite, "Use my current location" recognizes a saved city, and the app is ready for iOS 27.

A Home Screen widget. Add it to see the air right now and the next 24 hours at any saved place, in two sizes. Tap it to open that place. Each place now has its own Overnight switch. Turn it on for the place where you sleep, and Unhealthy air (AQI 151+) there will wake you. Everything else waits for 7 AM. Text now follows your phone's text size setting, and tapping a smokecast.org link opens the app. Also in this update: a tidier footer, a clearer accuracy page, the ozone reading stays on the map for the whole hour, the app opens with its logo instead of a blank screen, and there is an Open Settings button when alerts or location are blocked.

Smoke alerts arrive in the app. Save a place and tap its bell, and SmokeCast tells you when smoke is forecast to reach it, 6 to 18 hours ahead, with at most one alert per place per day. New option: wake me for Unhealthy air (AQI 151+), even overnight. And if SmokeCast is useful to you, there is now a small tip jar at the bottom of the screen.

Bug fixes and stability improvements.
