Sensecast: Forecast & Storms
Power Outages, Alerts, Models
Free · In‑App Purchases
Most weather apps tell you what. This one tells you why — 18 forecast sources compared side by side, and the science behind every number.
Most weather apps just show a number. Sensecast shows you why it feels that way.
Sensecast combines multi-model forecasts, Doppler radar, power-grid outages, and natural-hazard tracking in one weather app for iPhone and iPad. Compare 18 forecast sources — including national weather services and global supercomputer models — track live U.S. power outages, watch Doppler radar, and follow earthquakes, wildfires, hurricanes and other tropical cyclones, plus U.S. tornado reports. Then tap any metric to understand the science behind it. No account required. Fully localized in Spanish and automatically follows your device language.
FEELS-LIKE & CONDITIONS
• Apparent temperature: whether humidity (Heat Index) or wind (Wind Chill) is driving the difference.
• Dew point comfort scale (under 55°F crisp; 60–65°F muggy; over 70°F tropical).
• UV index, humidity, barometric-pressure trend, and a wind compass with Beaufort scale.
• Air Quality Index (PM2.5, PM10, ozone): EPA AirNow in the U.S., global estimates elsewhere.
18 FORECAST SOURCES INCLUDING 3 SUPERCOMPUTER MODELS
• 15 forecast sources free — NOAA, MET Norway, DWD (Bright Sky), UK Met Office, Environment Canada GEM, Météo-France, JMA, CMA and more.
• Smart routing uses your country's own weather service where it has a live feed.
• Sensecast Pro adds the ECMWF, HRRR and ICON supercomputer models and a side-by-side comparison grid with consensus and model-spread chips.
DOPPLER WEATHER RADAR
• The past 2 hours of radar, plus about an hour of nowcast.
• 4 color schemes (Universal Blue, Classic NEXRAD, Dark Sky, Titan), 3 map backgrounds, and an on-device tile cache.
NATURAL HAZARD TRACKERS (FREE)
• USGS earthquakes (M2.5+, 500 miles), NASA FIRMS wildfires (150 miles, ranked by Fire Radiative Power), GDACS cyclones in every basin, and SPC tornado reports and outlooks in the U.S.
• Optional background alerts for nearby earthquakes (M4.0+) and wildfires, with clear disclosure before background location is used.
LIVE GRID GUARD — POWER OUTAGES
• U.S. county-level outage counts from the Department of Energy's ODIN feed (participating utilities), a weather risk index for power lines, utility hotlines and outage-map links, and a blackout guide.
• Grid Guard storm and outage alerts are a Sensecast Pro feature.
WEATHER ACADEMY
• A searchable 20-topic glossary. Tap any metric for a plain-language analogy, then the science.
WIDGETS & LIVE ACTIVITIES
• Small, Medium and Large Home Screen widgets, plus circular, rectangular and inline Lock Screen widgets.
• Live Activities on the Lock Screen and Dynamic Island.
APPEARANCES
• Free: Dynamic (particles) and Clean Weather Sky (gradients).
• Pro: Atmosphere (photographic skies per condition and time of day, with overlays), OLED Stealth (true #000000), Custom Photo (on-device).
• Sleet, hail, and haze included. Overlays pause in the background.
PRIVATE BY DESIGN
• No account, no ads, no third-party tracking or analytics SDKs.
• Location goes to weather and hazard services — never to an ad network. Custom Photo stays on your device.

Ratings & Reviews

Sensecast 1.1.0 — the biggest update yet.
HAZARD MAP (PRO)
A new full-screen map layers every hazard feed onto one view: SPC storm reports and the Day 1 convective outlook, NWS warning polygons, USGS earthquakes, NASA FIRMS fire detections, GDACS cyclone tracks, county-level power outages, the SWPC aurora oval and nearby tide stations. A layers sheet toggles each feed and remembers your selection between launches, a 24-hour / 3-day / 7-day window scopes the time-aware layers, tapping a feature opens a details sheet with attribution, and a collapsible legend explains every colour on screen.
WEATHER WALLPAPER (PRO)
Your wallpaper can follow the weather: 44 scenes matched to the current condition and time of day — dawn, day, sunset, night — so it always agrees with the app. All six canvas styles are offered: Dynamic, Clean Weather Sky, Atmosphere (the photographic sky plates), Custom Photo, OLED stealth black, and the verified downloadable Photo pack. The wallpaper only changes when the scene does, and a "Get Sensecast Wallpaper" Shortcuts action enables scheduled or Focus-triggered changes.
TIDES (PRO)
Pro locations show the tide picture on the dashboard — the next high or low with a live countdown, a 24-hour curve and the reporting station. The full Tides screen carries a 48-hour view, a 7-day highs/lows table, and observed water level against the prediction where stations publish it. U.S. coasts use NOAA CO-OPS; everywhere else uses TideSpy.
PRO ACCOUNTS
Email sign-in is live: purchases made on the web unlock Pro on every signed-in device, and verified store receipts attach to your account automatically. The membership card names your plan, the day the paid period ends — "Never expires" for lifetime — and your device count, and Manage Subscription routes to the store you actually bought through.
WIDGET COLOUR THEMES (PRO)
Home-screen widgets can wear Dark Slate, Cyber Cyan, Solar Warmth, OLED Black or Aurora Teal — or keep following the weather for free. Each widget's theme is independent via Edit Widget.
AND MORE IN 1.1.0
• A real aurora painted into the night sky when NOAA's Kp index says one is visible at your location — never estimated, and it respects Reduce Motion
• Hourly UV index: a fifth metric on the forecast chart switcher and a value on every hour card, with solar-angle estimates disclosed per cell
• Weather Academy doubled to 43 plain-language glossary terms — fronts, CAPE, the cone of uncertainty, rip currents, tides and more — in English and Spanish
• Tracker sections (aurora, hurricane, earthquake, wildfire, tides, models) are now Pro behind a blurred preview card — Tornado Tracker stays free
• Onboarding rebuilt: pick your dashboard up front, severe alerts ask for notification permission at the moment of intent, units preset from your location's country, and a celebration finale — all full-window on iPad
• One design system: shared spacing, corner, text and motion scales across every card, sheet and screen — tappable cards gently scale while pressed
• Complete Spanish: every screen, home-screen widgets, Live Activities, Shortcuts, permission prompts and the VoiceOver layer
• Widgets matured: a normalized type scale with a readable floor on widgets and Live Activity, and gallery previews that mirror what ships
• Air quality names the concrete reporting monitor, and action-day declarations join the Pro alert
• Location pills read "City, ST"; radar's declutter toggle produces a truly clean map; alert banners give the issuing office its own line
• API keys moved into the Keychain with legacy copies migrating away; radar prefetches tiles so playback runs from cache; the Outfit typeface ships in-app instead of contacting Google Fonts
• A drag on a locked dashboard card now scrolls instead of dying, and the dashboard scrolls clear to the bottom edge
