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.
