Appolicious:手機應用搜索引擎是一個手機應用（iPhone/Touch）分享社群，你可以分享自己的iPhone/Touch應用，分享自己的手機應用列表，給手機應用寫評論，評級，下載免費的手機應用軟體等等。
使用者註冊之後首先需要選擇自己的手機裝置（iPhone 3G、iPhone 3Gs、iPod Touch、iPod Touch 2G、Original iPhone），選擇自己感興趣的應用型別，此外Appolicious的獨到之處是引入了Follow機制，和傳統的SNS網站的好友機制不同，使用者可以選擇Follow使用者來了解他人分享的應用軟體，同時使用者也有Block自己的Follow者的權利。
這樣一來，手機軟體的評分也有三種:一種是整站使用者的評級得分；一種是你Follow的使用者的評級得分；還有就是Follow你的使用者對此軟體的評分。個人覺得如果自己的Follow的群體是一個可信賴的人群，那麼自己Follow的使用者群的評分應該比整站評分更有價值。
Appolicious就是一個很好的將手機軟體應用和Twitter的這種Follow相結合的一個網路社群，對於傳統的分享社群而言，一直都是採用好友的機制（即相互加為好友），而對於類似於軟體分享而言，其實很多人也都希望瞭解更多的使用者的使用情況（很多情況下並非自己的朋友），這樣一來這種Follow就大有用武之地了，並且加入這樣一種機制之後，對於軟體的評級資料也有了更多可以挖掘的資訊。
