As an avid My-Cast fan, I currently use 6 apps from the App Store.
1. MyRadarPro
2. RadarUS+
3. WeatherBug
4. AccuWeather
5. Wunderground
6. The Weather Channel
I have yet to find a weather app that was as comprehensive as My-Cast. There is Garmin Pilot, which, is extremely expensive, but it does NOT have the alert factors as My-Cast.
Until someone either takes the time to build a weather app that is/as sophisticated as My-Cast once was, I think we are all just going to have to say goodbye to the days that one App answered every weather geek’s question and had severe alerts, like tornadoes, lightning and any severe storm 24/7, plus any location that you asked to be notified.
I remember a night during that terrible tornado season 6/8 yrs ago that was spread from Texas through Alabama up to Pennsylvania at an Eastern diagonal. My-Cast woke me up, and informed me that a friend was in fact in danger of severe tornado. I immediately contacted my friend and she was grateful that I had alerted her out of the dead of sleep. Today, I have no such faith in any app on iOS or otherwise.
