Weather worth looking at, and a forecast you can trust. Most apps give you one model's guess. Atmos weighs several of the world's best forecasts by how accurate they've actually been, and gives you one honest verdict. A LIVING SKY A real, moving scene: sun and moon in their true places, clouds that thicken before rain. 128 hand-built skylines, from Tokyo to Tromsø. NORTHERN LIGHTS, FORECAST HONESTLY Live space weather fused with your cloud, darkness and moonlight into an hour-by-hour aurora chance, plus a three-night outlook. Overcast? Atmos says "clouded out" instead of getting your hopes up. ONE HONEST VERDICT Several models, blended and graded against real ground stations. When they disagree, Atmos shows who, about what, and by how much. EVERY HOUR, IN COLOUR Temperature, rain, wind, humidity, pressure and UV. The whole day, readable in a second. RAIN BEFORE IT ARRIVES Live radar and a minute-scale nowcast (where supported), and your next dry window. PLAN THE WEEK "Turning cooler and wetter next week." Saturday vs Sunday, in one sentence. YOUR PLACES, ON YOUR HOME SCREEN Follow the cities you love, with widgets in every size. Native on iPhone and iPad. PRIVATE BY DESIGN No account. No ads. No tracking. Atmos+ unlocks the full multi-model Verdict, the animated radar, the complete Portal and widgets — try it free for 7 days. The core app is free. Atmos+ is an auto-renewable subscription. Payment is charged to your Apple ID at confirmation of purchase, and it renews automatically unless cancelled at least 24 hours before the current period ends. Manage or cancel anytime in your Apple ID settings. Data from MET Norway, Apple Weather, DWD, Pirate Weather, WeatherAPI, Open-Meteo and RainViewer.
