24me is a calendar/to-do list app that's all about helping you get your life in order and plan things out. With the addition of its new Forecast feature it should be even more effective.
Forecast is a new "long range weather forecast" - powered by WeatherPlanner - that provides an entire year's worth of knowing what the weather is supposed to be like for any event or activity you may have planned. Family vacations, parties, road trips, and whatever else might require you or other people to go outside.
The new Forecast update will be available for 24me first thing tomorrow. Probably even later this evening, what with the App Store update schedule and all.
