Majority of the people uses android Mobile furthermore utilizes the play store ability ordinarily. Play store give extraordinary number of utilization yet unfortunately few of those applications are extortion. Such applications harm to telephone furthermore might be information robberies. Henceforth such applications must be checked, with the goal that they will be identifiable for play store clients. Positioning coercion in the convenient App business part suggests fake or deluding practices which have an inspiration driving thumping up the Apps in the famous rundown. So we are proposing an application which will prepare positioning based confirmation, rating based proof and survey based confirmation with stop words evacuation, NLP and mining strategies. So it will be less demanding to choose which application is extortion or not. There are more than 1.6 million Apps at Apple's App store and Google Play.

Furthermore, we investigate three types of proofs, i.e., ranking based evidences, rating based evidences and review based evidences, by modeling Apps’ ranking, rating and review behaviors through statistical hypotheses tests.
