WeatherAlarm Notifier is a free iPhone app developed by Ales Fleischmann. It falls under the lifestyle category with a specific focus on weather. This handy app ensures that you never forget your umbrella again by notifying you up to 2 hours before it rains.

One of the standout features of WeatherAlarm Notifier is its ability to detect the speed and direction of rain. This means that you won't receive a notification when the rain is moving away from your location, saving you unnecessary alerts. The app uses real-time calculations of radar images from selected countries and runs on the developer's servers, allowing for accurate predictions of precipitation for approximately 2 hours ahead.

WeatherAlarm Notifier is particularly useful for outdoor activities such as hiking, skiing, motorcycling, and biking. It can also serve as a reminder to move your car to a safe place when hail is approaching. The app provides push notifications when rain danger is detected in your current location.

With animated radar images overlaid on maps, WeatherAlarm Notifier offers a visual representation of the weather conditions. Currently available for the USA, Slovenia, Croatia, Belgium, Netherlands, and Germany, this app provides real-time information on the direction, strength, and speed of incoming precipitation. It even estimates the time of arrival for precipitation cells.
