DingDongApp:手机照片互动应用是一款用户拍一张照片，发给一个或几个朋友，然后朋友们再发照片回来，就像以照片的形式发信息一样；和你的朋友进行照片互动，只要叮咚一下，图片即可互动分享了。

DingDong 的玩法有自己的特点，而基本的 idea 是希望将你与朋友的联系变得极其简单而又直观。像按门铃那样拍张照片，这时就会 DingDong 一下你的好友。这时好友可以选择添加表情或 DingDong 一张图片回去。你们的互动会在地图上显示出彼此位置的连线。

DingDong 不能添加文字，也没有传统照片的分享机制，一切都发生在这个 app 之中——不会有来自 Twitter 这些社交网络的反馈，它只靠 app 本身来吸引用户。

DingDong 是完全私密的，你不能被关注或关注别人，不能广播，也不能签到。每次都你可以决定能看到你图片和位置的人，就像群发短信时选择接收人一样。

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.
