Interactive radar with animated playback and immersive full-screen mode, automatically centered on your location.

— AIR QUALITY — Real-time AQI with pollutant breakdowns — PM2.5, ozone, smoke, and more — so you know what you're actually breathing before you head outside. Coverage across Canada and the US.

— HOME SCREEN WIDGETS — A large collection of beautifully designed widgets for your home screen and lock screen. Choose from minimalist, glassmorphic, terminal-style, radial, chart-based, and more. The free METAR widget shows live aviation weather right from your home screen — no app needed.

Each widget can follow the app's current location or be pinned to any city you choose.

— AVIATION WEATHER — For pilots and weather enthusiasts: live METARs and TAFs for nearby stations, VFR/MVFR/IFR/LIFR flight category indicators, winds aloft, and 24 hours of historical METAR observations — all in one dedicated tab. Covers airports and aerodromes across Canada and the US.

— ALWAYS READY — Background refresh keeps widget data and offline forecasts current even when the app is closed. Severe weather notifications deliver local alerts the moment conditions change.

— MORE — • Apple Spotlight integration — search any city from your home screen • Share extension — open Cloudbase directly from Safari • Multi-location search with instant switching • Fully configurable units: metric, imperial, or mixed • Optimized for iPhone and iPad • Dark mode throughout
