Google has issued one application named Who's Down which helps users make plans together with their friends.
Microsoft's Garage team recently developed some experimental applications. He had released one of these in July called Tossup and it did pretty much the same things. Now it seems that Google got jealous and moved on creation and launching an app called Who's Down, which runs on iOS and Android and allows users to hold group chats and plan where they'll hang out at night in real life.
Upon opening the application, the user greeted his friends and essentially states that he is available for "a walk". After this step, the user can go to see what are the plans of his friends for walks so far and start talking to them through the application itself. Other friends who are also available may well be added to these conversations. Each session for where you will be with your friends lasts three hours and then is deleted.
You can download the iOS and Android app from iTunes Store and Google Play Store respectively. You must have an invitation from a friend to create account. For now you can ask the manufacturer to send you an invitation. Users after registering can invite their friends to use it.
