Featuring Critical Alerts that override Do Not Disturb settings for the most important alerts, StormWatch+ aspires to be your daily weather app of choice, no matter the weather! Access the most pertinent weather information - like current conditions, hourly and extended forecast, and local or regional radar - quickly then get on with your day. Finally a weather forecast you can trust! Harnessing the local knowledge and dedication of more than 2,000 National Weather Service meteorologists nationwide, our goal is for StormWatch+ to replace the fickle, computer-generated, single-icon forecast found in most weather apps! SW+ ALERTS IN-APP UPGRADE For the ultimate severe weather preparation tool, check out our (also upgraded!) alerting technology, SW+ Alerts. SW+ Alerts is a life-saving service that sends you push notifications whenever hazardous weather threatens your specific location. Once again relying on the expertise of over 2,000 NWS meteorologists nationwide, SW+ Alerts compares multiple specific locations you select with weather watches and warnings issued by your local NWS office. Alerts are sent to the app ONLY if you are in the path of hazardous weather, eliminating the confusion associated with county-wide warning sirens or NOAA Weather Radio alerts. Simply tapping on a push alert will show your location with respect to the warning boundaries on a map, as well as display the full text of the alert. In addition, Critical Alerts “wake-me-up” audio and voice alerts will sound for the most severe warnings.^ In addition to monitoring fixed locations, the “EnRoute” feature allows you to receive severe weather alerts while on the go! Simply enable EnRoute and the app will track your location and alert you if you drive into a warned area, whether you know your exact location or not! Features of StormWatch+ Alerts include: * Your choice of push notifications in the event of: - Tornado Watches and Warnings - Severe Thunderstorm Watches and Warnings - Flash Flood Watches and Warnings - A suite of Tropical weather alerts - A suite of Winter weather alerts * Notifications sent even if the app is not running and your device is not in use * Push notifications accompanied by audio alerts that will wake you up (for Tornado and Severe Thunderstorm Warnings^) * Alerts for up to 5 fixed locations, which can be changed at any time * EnRoute, which uses your device's GPS location to actively monitor for severe weather as you travel * Map showing warned area and your location * Quiet time – to temporarily stop alerts during a specified time of day * Status buttons to disable individual locations StormWatch+ provides personalized weather alerts in the palm of your hand! ^ NOTE: Audio alerts feature Critical Alerts, which will sound wake-me-up audio at full volume and override Do Not Disturb for the most severe warnings, even if your device is silenced.

The call

Supermoon's advantage is rating (5.0 vs 2.8) and in-app purchases (none vs 2). On ads, device support and iOS requirement there is nothing between them.
