I have been using this app for last couple of months and my experience is good with this app. It has some very nice features.
You can do recharge, pay bills, book cab and even order food from this app. And the best part is that they give cashback for every transaction.
And also they have a section called offers where you can get offers of all apps like freecharge, paytm, pvr etc. It is quite a good app and it provides lot of cashback than any other recharge app. Also customer support is very good. They reply to your mails typically within hours. Overall this app is very good.
