Air Today

Air Today turns air quality into something you can feel. Instead of burying you in numbers, it paints the sky — the entire screen shifts from clear blue to hazy amber to deep red, so you know the moment you open the app whether it's a good day to be outside. The number is there if you want it. But the real answer is the verdict above it: "Great day to be outside" or "Limit prolonged outdoor exertion." Plain language, no interpretation required. ALWAYS CURRENT Air Today shows the nearest monitoring station when it has reported in the last two hours and is close by. Otherwise it shows a live estimate for your area from the Copernicus Atmosphere Monitoring Service — and always says which you're looking at and how fresh it is. The weather right now, temperature and sky, sits under each place's name. KNOW WHAT YOU CAN DO TODAY Advice for the things that actually matter: • Running and cycling — how hard can you push? • Walking and outdoor dining — is it pleasant out there? • Playground time with kids — are the little ones safe? When it isn't a great time, Air Today tells you when the air will be cleanest, from the hourly forecast. PERSONAL TO YOU Tell Air Today three quick things — asthma or another respiratory condition, ozone sensitivity, kids in the household — and the advice adapts. Your answers never leave your devices. SEE WHAT'S COMING An hourly forecast for today and tomorrow, then each day's worst hour for the days after (4 days ahead in Europe, 5 elsewhere). Going for a long run tomorrow morning? You'll know the best time. GET WARNED WHEN AIR GETS WORSE • Alerts when the air reaches the level you choose, here and in your saved places • Daily verdict at the time you choose • Best time to go out, from the hourly forecast • Spike alerts when the air worsens fast — often a sign of smoke nearby Every alert is independently togglable. No spam. YOUR STANDARD, YOUR CHOICE Switch between the US EPA AQI, the European Air Quality Index and the UK Daily Air Quality Index. The European and UK indices are calculated from pollutant concentrations with each index's own averaging, and the verdict, activity advice and alerts follow whichever you pick. EXPLORE NEARBY STATIONS A built-in map shows monitoring stations around you, each pinned with its reading. TRACK MULTIPLE LOCATIONS Add up to 6 places and swipe between them — each clearly named, with its local time and weather. WIDGETS & SHORTCUTS • Air quality, Activity Check and Best Window widgets • Lock Screen and Home Screen widgets, with a refresh button • "What's the air quality in Air Today?" / "Should I run today with Air Today?"
