Forecast: Provides basic current weather info and 10-day forecasts for the quick hit but also allows you to scroll through functions, such as barometer readings, wind speed and direction, sunrise and sunset, and the moon phases, among others. It also has a radar overlay to view the last six hours of storm movement. It allows you to set up push alerts so your phone will buzz if severe weather is nigh.
Dark Cloud: The radar overlay is not as detailed or as precise as on other apps.
Numbers: $1.99; iTunes
