Umbrella here is a light that can be attached on an Umbrella Here which is controlled by a mobile app that tells people that this umbrella is available for sharing. Just like the light you would see on a taxi. When the light is on, it represents that strangers are welcome to come in and share your umbrella. This app is the controller for your Umbrella Here. You can use it to control it's color, records time and places of where you are using your Umbrella Here and it also helps you find people with an umbrella near you during a rainy day.
