From last few years, mobile technology has been received much more attention since it is most popular and basic need of today's world. Due to the popularity, mobiles are major target for malicious applications. Key challenge is to detect and remove malicious apps from mobiles. Numerous amounts of mobile apps are generated daily so ranking fraud is the one of the major aspects in front of the mobile App market. Ranking fraud refers to fraudulent or vulnerable activities. Main aim of the fraudulent is to knock the fraud mobile apps in the popularity list. Most App developer generates the ranking fraud apps by tricky means like enhancing the apps sales or by simply rating fake apps. Thus, there is need to have novel system to effectively analyze fraud apps. This paper provides a survey on various existing techniques with the novelties highlighting the need of novel technique to detect fraud mobile apps. This paper is motivated by arising need to detect fraud apps with less time. In proposed system, we add recommendation based on the modified ranking.
