“This is the weather app of all time. The critical alert feature is pretty much instantaneous, and the notification sound is very loud. I also enjoy that you can view the Storm Prediction Center outlooks at a click of only a few buttons, and you can filter/star your local Weather Forecast Offices, you can listen to the local weather radio, and there is an interactive weather radar!!!”

“An outstanding app for weather and EAS enthusiasts! Everything is well-organized, with radar, weather radio streams, and alerts all in one place. The iEMBot alerts are just as fast—if not faster—than X, making it a must-have for staying informed. Highly recommended!”

“I love this app so so so so so much very helpful! Even works well when you have little service! If I could I would replace every iPhone weather app with this one. If you are debating downloading this app DO IT!!! You will always know when you need to carry your umbrella! 🌧️”
