I personally use this UPI app but personally I don’t like this app due to the reason that this is not easy to use and its interface is so complicated as compared to other upi apps like BHIM OR PHONEPE.
If you want better comfort with this app I think you don’t but if you want better security then I recommend you to use this app.
The main reason behind it is that the one who is using this app first time feel complicated and it take time to understand properly.where as in BHIM app its very comfortable to use for everyone.
