I am using this app from last one month.It is great application.
I earned lot of cash back by sharing among friends group.there is no limit of earning cash back.If you compare with other online application they have limited cash back offers for limited time frame. Please note you cant transfer cash payback earned to Bank account.I usually pay my electricity or phone bills.
Onces you link your Bank through UPI you will get Rs 75 n ur friend will also get Rs 75. and if you do first transaction you will get 100% cash back.
Overall this is nice application n very useful application.
