Skylight vs Storm Window

Skylight is a weather app for people who want to know how much to trust the forecast — not just what it says. Every number tells you where it came from. Radar frames are labeled observed or forecast, never blurred together. Storm risk says it is reading forecast instability, not detected lightning. A trip three weeks out is answered by the climate record, and says so, instead of pretending to be a forecast. Where a provider has no data, Skylight shows you nothing rather than a confident zero. On iPhone, iPad and Apple Watch. One purchase covers all three.

Air quality comes from the EPA's AirNow monitor network. Tides and hurricane tracking come from NOAA. Historical weather is reanalysis of the global climate record, which is a reconstruction rather than a reading taken in your garden, and Skylight says so where it matters. Skylight Brief is composed from the forecast by rules, so the same conditions always produce the same words. Explain my forecast uses Apple Intelligence on your device — nothing is sent to a server, and it is held to the facts Skylight gives it. No account. No ads. No tracking. Your location is used to fetch weather and is never stored or sold.

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.
