Reliable. Grape social assistant is an acquaintance social application based on mobile phone address book. It associates the mobile phone address book with friends on Tencent Weibo, Renren.com and Sina Weibo, which are the three most popular social platforms at present, so as to refresh the dynamic information of contacts across social platforms and support one-click synchronization of social data of contacts to the local address book. Grape socialization allows users to grasp the social dynamics of their acquaintance circle in a "three-dimensional" way. The core value of grapes comes from the barriers to quickly establish this relationship. In other words, as long as you have the phone numbers of your family and friends, you can quickly import their relationships into the grape social network and quickly form your own acquaintance social network on your mobile phone, so that you can fully read the updated information of the social networks of your family and friends.
