DaySky Forecast vs Beyond UV

Know what matters in today's weather. Check the next 24 hours and the 10-day forecast. See official alerts and find favorable times to go out. A CLEAR SUMMARY The automatic summary highlights changes that may affect your plans: when rain may arrive, notable heat or cold, wind and gusts, fog, high UV, or an evening cooldown. When nothing stands out, it says the day looks calm. HOURLY AND 10-DAY FORECASTS Check current conditions, the next 24 hours, and the 10-day forecast. Sunrise and sunset appear between the forecast hours when they occur. PLAN TIME OUTSIDE Choose a day with enough hourly forecast data and a duration of 30, 60, or 120 minutes. See up to three periods that fit your temperature, precipitation-probability, and wind preferences. Daylight and official weather alerts are considered, and high UV is flagged. If no period qualifies, the app explains the main reason. These are weather comparisons, not safety guarantees. OFFICIAL WEATHER ALERTS Read available official weather alerts and open details from the issuing organization. SEVEN WEATHER METRICS Explore feels-like temperature, humidity and dew point, wind and gusts, UV index, precipitation, visibility, and pressure. Each metric has an hourly chart and day selector. SAVED PLACES AND WIDGETS Search for cities and save places you check. Each one shows the current temperature and local time. Choose a place for your Home Screen or Lock Screen widgets. OPTIONAL REMINDERS Set a daily reminder to check the forecast or a reminder for the start of a suggested period. Notifications ask you to check the latest forecast; they are not real-time weather alerts. PRIVACY No accounts, ads, usage analytics, or third-party libraries. Location is requested only while you use the app. Coordinates required to provide weather information are sent to the necessary Apple services; the developer does not receive those coordinates. Saved places remain on the device. ACCESSIBILITY AND REQUIREMENTS Designed for VoiceOver and large text, including accessibility text sizes. For iPhone running iOS 17 or later. Weather data is provided by Apple Weather.

UV Index is useful, but it is not the whole day. Beyond UV shows Apple Weather's UV Index next to UVA Context, Beyond UV's own modeled estimate of longer-wave UV, on the same familiar 0–11+ scale. The UV Index is weighted to sunburn and barely counts UVA, which gets through clouds and window glass all year. UV NOW uses the higher level of the two signals. The numbers are never added or averaged. Tap Start now when you head out and Beyond UV reminds you to reapply sunscreen, with a Lock Screen Live Activity, one-tap Reapplied, and an Apple Watch app. Set a UV alert at the level you choose for each place. A 5-day hourly forecast shows how UV Index and UVA Context move through each day, and Protect can find a lower-UV time for an activity you can move. Answer a few questions to see your sun risk profile: your exposure level, a protection score, and the one change that helps most. Add your skin type to see an estimated burn time range for unprotected skin at today's UV. Estimate only, not medical advice. Home Screen and Lock Screen widgets keep UV in view. Search any city worldwide, or use Current Location. Learn answers common sun questions from reviewed answers stored on your device, and you can share any answer as a card. No account. No ads. No analytics. UVA Context is a forecast-based estimate calculated on your device. It is not a UVA measurement, not an official UV index, and not a personal exposure reading. Beyond UV does not diagnose skin conditions or give medical advice.
