This app lets you earn a decent money but to accumulate that small amount of money it take months. It took 2 months for me to accumulate Rs150.
They give offers by downloading app from playstore, register in that application and keep that app for some time like one month or two it depends. Taskbucks lets you recharge your mobile or can withdraw for paytm cash.
But paytm cash is limited, it wont let more than Rs25 in one week. Thats a huge drawback.
