Storm Window helps you find safer outdoor windows when weather risk is changing. Instead of giving you another raw forecast, Storm Window turns hourly weather data into a clear outdoor risk timeline, highlighting when conditions look clear, marginal, stormy, or severe. Built for runners, cyclists, walkers, golfers, beach days, trail time, work crews, and anyone who plans around lightning, heat, wind, air quality, and rain. Core features: • Clear "go / wait" style outdoor risk guidance • 48-hour hourly risk strip, shown as bars or dots • Lightning-aware storm risk • Heat, air quality, wind, UV, rain, and snow context • National Weather Service alert awareness • Current-location planning, plus one saved place • Home Screen widgets and Apple Watch support • Built-in explanations of what's driving each hour's risk Storm Window Pro adds: • Multiple saved locations • Activity-specific risk profiles (runner, cyclist, golfer, and more) • Custom activity profiles • Personal heat and AQI sensitivity tuning • Full hourly detail on tap • Driest-stretch highlight within your safe window • Per-location widgets and complications Storm Window Pro+ adds: • Trips: pin an upcoming event and get its own safe-window forecast and alerts • "Should I Go?" activity-aware guidance • Forecast change reviews and 48-hour forecast summaries • Apple Intelligence-powered risk explanations on supported devices — all features work without it Storm Window uses deterministic risk rules for its core safety assessment. Pro+ guidance does not replace the underlying risk rating. Storm Window is forecast guidance, not a guarantee of safe conditions. Weather can change quickly. When thunder roars, go indoors.

FirstDrop Rain Radar
Read full descriptionHide full description
FirstDrop tells you when rain will reach where you are, before it does. THE IMPORTANT PART FIRST The app opens with a clear answer: "Rain in 14 min." Or: "Dry for the next two hours." The radar is at the top, with measurements underneath. No searching required. ALERTS THAT REACH YOU Get a push notification when rain is on the way. See a countdown on your lock screen as it approaches, or use the home screen widget. You don't need to open the app to get the answer. LIVE RAIN RADAR Animated rain radar powered by data from DMI, MET Norway, SMHI, FMI and EUMETNET OPERA. The radar covers Europe and shows how hard it is raining, measured by a national radar in the Nordics and estimated from the European radar composite elsewhere. Drag the timeline to see where the rain and showers are heading. SEVERE WEATHER IS FREE FOR EVERYONE Official weather warnings are sent directly to you, whether you pay for FirstDrop or not. The app does not replace official warnings. It passes them on and adds its own radar on top.

Verdict
The clearest difference is ads: Storm Window at none against FirstDrop Rain Radar's shown. FirstDrop Rain Radar's advantage is update cadence (every 2 days vs every 5 days) and iOS requirement (16.4 vs 26.0). On price, in-app purchases and device support there is nothing between them.
