Mcent is a App for earn free recharge this application is available on playstore and lots of people earning from this .
But I would like to tell you behalf on my uses experiences
It's a App based earning when you download a app through Mcent and create a new I'd or use 2 or 3 minutes they send 5- or 10 rupees for task completions and it's have a policy included with it after 7 days 5 rupees after 15 days 10 rupees this type of policy added in every app.
And in this app earning is very low and very hardly.
So that's why I don't recomend this app I recomend MouthShut If u wanna earn more only for sharing experience .
