DingDongApp手机相片互动应用程序是用户将照片发送给一位或几位好友，然后这些朋友又将照片发送给另一位好友，就像是将信息发送给照片一样;与好友进行相片互动，只需叮咚一下，图片就可以互动共享了。
dingDong的游戏有其自身的特色，而dingDong的基础就是想让你和朋友的联系变得非常简单和直观。照一张像按门铃一样的照片，然后让DingDong告诉你的朋友们。此时，朋友可以选择添加表情或者DingDong图片返回。你的互动将在地图上显示出彼此位置的联系。
DingDong无法添加文字，也没有为传统照片的共享机制，所有的事情都发生在app上——不会有来自Twitter等社交网络的反馈，只是因为app本身吸引用户。
dingdong是完全私人的，你无法被关注或关注他人，无法进行广播或注册。每一次你都可以决定谁能看到你的照片和位置，就像在群发短信时选择收件人一样。
Ding Dong is the easiest and fastest way to let a friend know where you are and what you’re doing. Send your location and a photo with just one tap.
