Paytm is far better than this app. I am saying this because in Mobikwik you cannot use the money in the wallet completely you got as cashback, only 10% of the Mobikwik cashback can be used, that too is applicable on transactions above some fixed amount of transactions. So, almost all the money as cashback you get is waste.
Now, the deals this app offer are also not good enough to make it considerable. Little app and freecharge are another excellent alternatives to get nice deals and topups in mobile, DTH etc.
This app is acceptible only at some selected places. So it is also useless at other places.
This app is of no use, there are no perks of having it.
