WeatherAlarmApp vs VortexWeather

WeatherAlarm helps you follow the weather at home and at the other places that matter to you. Add a parent’s house, a child’s college town, or anywhere you want to keep an eye on. Each saved place has its own alerts, conditions, forecast, and weather context. All for free, with no ads, no subscriptions, no tracking, 100% free, like apps used to be. When the National Weather Service issues a warning, WeatherAlarm checks the places you monitor and sends a location-specific alert. Open it to see what happened, which place is affected, and the latest available storm context. WHAT’S NEW IN VERSION 3 Apple Watch: See your saved places and their warning status in the paired Watch app. Add a complication for a quick glance from your watch face. Set up and manage places on iPhone. Live Activities: Eligible active Tornado and Severe Thunderstorm Warnings can appear on the iPhone Lock Screen and in the Dynamic Island. See the affected place, warning level, and remaining time as the warning changes. Weather on glass: On a location’s detail screen, weather-inspired light and motion bring current conditions into the scene. The app chooses the effect automatically; you can turn it off in Settings. MORE WAYS TO KEEP WATCH • Monitor multiple saved locations independently • Get official weather alerts for the places you choose • Explore radar, warning areas, and weather layers on the map • See current conditions, hourly details, and a multi-day forecast • Keep alert information close with iPhone widgets • Review storm details after a warning ends when a report is available WeatherAlarm is free, with no ads or subscription. No account signup is required. Severe weather alerts for the people you love. WeatherAlarm is an independent app. National Weather Service alerts and other weather data depend on their source and network availability. Keep more than one way to receive urgent warnings.
