SkyForge makes the weather radar the whole app — a full-screen, buttery-smooth animated map is your home screen, and everything else floats cleanly on top. RADAR THAT MOVES • Smooth, motion-interpolated radar: the past two hours, then up to an hour of forecast radar where it's available • 3D storms — heavy rain rises off the map as shaded clouds that cast shadows • Live wind streams — thousands of moving particles showing direction and speed • Temperature overlay with a color-graded legend • Show precipitation, temperature and wind together • Fronts & pressure from NOAA's surface analysis • Zoom out far enough and the map becomes a spinning 3D globe, colored with NASA satellite land cover A FORECAST WITH DEPTH • 10-day forecast — tap any day to expand a plain-English brief • Interactive charts for every day: temperature, precipitation, UV, wind, humidity, visibility, and pressure — drag to pinpoint any minute • Hourly forecast, current conditions, "feels like", and high/low • Air quality (US AQI), UV index, sunrise & sunset, dew point, and more BUILT FOR WHERE YOU ARE • Automatic radar and forecast for your current location • Save cities and reorder your list with a long-press • Dark and light map themes that remember your choice SEVERE WEATHER • Live watches, warnings, and advisories from the US National Weather Service, right at the top of your screen when they matter HONEST BY DESIGN • 100% free and ad-free • No account, no sign-up, no tracking • Your location is used only to fetch weather — never stored or sold Weather data from Open-Meteo, LibreWXR, RainViewer, NOAA / National Weather Service, NASA GIBS, Iowa State Mesonet, and OpenWeatherMap.

Verdict

The call

The clearest difference is in-app purchases: SkyForge at none against Arc's 3. SkyForge also leads on device support (4 vs 2) and iOS requirement (15.1 vs 17.0). Arc's advantage is update cadence (every 2 weeks vs monthly). On price and ads there is nothing between them.
