Im using this app approximately morethan 2 years . They have only one task thats is attend the monthly survay and it is very iseful in india and also it is a indian suvay . The older version that is before the 2017 they are provide their reward thorugh may be mobile recharge, flipkart voucher or amazon voucher and after the 2017 they only provide amazon gift voucher and I got lot of recharges and voucher so it a trusted application . If you have any missed voucher or recharge you can sent a mail on their email they immediately verify and reply them . So trust at more .
