Fuse is an app that makes it easy for you and your friends to hang out by joining each other’s plans. The app Fuse lets you inform your friends on what your plans are (when, where and what) and that you want them to join you. Then your friends can accept or decline the join invite. JoinUs is different from other apps because it is not to plan business, school or events. It only focuses on how to make it easier for you to hang out with your friends on your free time.
