The two I use most are at opposite ends of the weather app spectrum. Both are free. One is crazy simple to figure out and use. The other is more complex but gives you detailed weather information at a glance.
Good • Weather • Underground
Think about what you want in a weather app for the iPhone. Current weather conditions. Weather forecasts. Weather radar for your area. Temperatures, and an option for multiple cities, and throw in a few alerts.
Of the two, Weather Underground is the more robust. It pulls weather data from over 24,000 different personal weather stations, does hourly forecasts, seven-day forecasts and sever weather push alerts.
Radar is animated and features both cloud cover and rain clouds. Weather details usually include temperatures, wind speed and direction, dew point, visibility, barometric pressure, and much more.
Weather data can be shared via Twitter, and Weather Underground captures data for multiple locations.
And, yes, a picture or two is worth more than a few hundred words. One glance to the Weather Underground home screen gives you what you need to know.
Now, let’s contrast all that glorious weather detail with the simple approach advocated by the Good Weather app.
If small is beautiful, is simple better?
Good Weather’s minimalist approach might be better of placed on a tile on the iPhone’s home screen.
Wait. The iPhone doesn’t have user configurable tiles on the home screen.
This clever app that seems so minimalist and pop art-like has a few things you won’t find on most other weather apps.
Games. It comes with 30 built-in weather mini-games, each based upon your current location’s weather forecast.
That’s a weather app that’s useful to help you pass, uh, well, the weather. It keeps track of your high scores.
Oh, and it also pinpoints you current location automatically, which would make it a perfect weather app for a floating home screen tile.
