I Had heard about Mcents from my frnds they told me that you can earn money by this app. I installed it in my phone and completed all procedures and I Have earn few money. BUT I personally not recommend any one to use this type of apps because using this
type of apps may risk your phone.
Apps which are installed through play store are verified by google and they are safe to use but apps which are not available on Google play store or we use any third party app to install it. It may harmful because it may theft your personal data like contact sms or pictures.
Also I have notice that some time when you install Mcent and they ask to install many apps to earn money. In few of apps you need to register it was harmful because you are giving ur email id they may mailed you spam mails or try to send junk mails.
Well I personally Don’t advice any phone to use Mcent. because I have also used it and find that it is useless sometimes you complete all procedures but they don’t give you credit. All you need to waste your time and data to install useless apps and register to unwanted app
