If you pull up the iTunes App Store and look at the Weather category,you will see a bevy of apps. 
You can spend here, download there, but in the end the majority of apps seen are a repackaging of each other. There are exceptions, however, to this. James Spann is most popularly known for his discontent towards “Crap Apps,” or apps that use the same computer generated forecast and muted radar to give you an inaccurate forecast at times.
Weather Underground (WU) has done a good job to get past this “stereotype” of weather apps. Their “Weather Underground” app has been a go to for me in looking at maps and forecasts. The app features their “BestForecast™” but also the NWS forecasts.
Sidenote: That sounds like an advertisement for the app, and if you want to call it a cheap plug for the product, then go for it. I do recommend the app to all I come in contact with looking for a good weather app.
Moving on, the company announced the debut of its latest app called “Storm.” WU and Intellicast, a Boston based weather company who is owned by The Weather Channel along with WU, teamed up to make “a highly advanced app for weather enthusiasts and storm trackers alike.” That quote intrigued me, mainly because this kind of venture is seen by smaller groups or people who want to make an app that breaks past the status quo that had been set. Apps like “RadarScope”, “AeroWeather”, and “Storm Shield” do that job well. Specializing in high quality radar, data, showing model data, or giving forecast info, and do well at their own specialization.
So I looked into “Storm” to see if the big companies can make and provide a detailed specialized app. What I’ve discovered it similar to the original WU app, just re-designed and with more detail. It’s not for your average person who wants to just check a forecast, but if you’re a more expected person in the science or want more detail, this app is worth the look.
The app opens up with a map and a row of “tiles” at the bottom. The first is alerts, showing if any advisories active. Following it is the “Current”, “Daily”, and “Hourly” with some settings and support tiles after. The hourly and daily tabs hold the forecast to the location selected. Charts and a list option are available, allowing the user to dive in and see details of a forecast.
The map allows a myriad of layers to be selected and added. This is an observation, and not confirmed, but it looks like Weather Underground is in charge of layer design, while Intellicast’s radar is used.
There is a lot of functionality within the program and it’s free. For a app called “Storm,” the sun shines bright.
