The simplest weather report ever - Umbrella Today send you a text message on days when you need an umbrella. For me that is every day, but for some of you this service may be useful.
I love the little details, such as the Umbrelletiquette:
“ When disembarking from public transit, one should keep their umbrella holstered until such a proper time as it may be safely wielded without impeding the general progress of fellow passengers."
Thanks to Kat for discovery.
