Deviant Weather — your weather, in context. Most weather apps tell you what the weather is. Deviant Weather tells you how unusual it is. Every reading — temperature, pressure, wind, humidity, and more — is compared against years of local climate history, so you instantly see what's normal for your location and what isn't. It's the difference between "68°F and cloudy" and "68°F — notably cooler and much cloudier than usual for this time of year." KNOW WHAT'S NORMAL. SPOT WHAT'S NOT. • A dozen conditions analyzed for anomalies — temperature, feels‑like, dew point, humidity, pressure, wind speed and gusts, cloud cover, UV, and precipitation • Baselines built from up to a decade of real local history for your exact location — not a global rule of thumb • "For this time of year" comparisons that account for the season and time of day • Thresholds calibrated to each place's own climate, so a small wobble never gets flagged like a true outlier • Plain‑language summaries with the numbers behind them: "Current temperature is 68°F vs. the historical average of 74°F — 6° cooler than typical" • Month‑to‑date trends and extreme‑event detection for the standout days SEE THE STORY, NOT JUST THE NUMBER • Interactive 24‑hour charts for temperature, pressure, and wind — current reading, historical average, and the deviation between them, all in one view • Tap any hour for an exact readout • A "normal range" band that shows the typical historical range at a glance • A 10‑day forecast with daily ranges, conditions, and a clear color language (cooler = blue, warmer = red) used everywhere BUILT TO LIVE ON YOUR DEVICES • Save your favorite places and add your current location • Syncs your locations and settings across iPhone and iPad through your private iCloud — no separate account, no third‑party servers • Privacy by design: precise coordinates stay on your device • Works offline with cached conditions, charts, and forecasts • A clean, adaptive layout for iPhone and iPad in full light and dark mode MADE YOUR WAY • Choose your units for temperature, pressure, wind, precipitation, and distance • Toggle confidence indicators, the normal‑range band, and more • Designed for accessibility — VoiceOver, Dynamic Type, Reduce Motion, and high‑contrast support throughout Powered by Apple Weather.
