Personally I am much more involved in digital payment methods, so I have almost tried every UPI App currently available on playstore, especially built for android.
I have already given ratings, but still I would like to mention one of very important thing related to UPI application specially comparing to other UPI apps such as BHIM UPI app. And the thing is we cannot change our linked bank account from AXIS UPI app linked to VPA address. I have personally checked or even many of using BHIM can change their bank account to use same VPA address by linking another Bank account. But in AXIS UPI app we have to add new VPA address to link new Bank account, which seems bit complicated according to me.
