I had used a lot of UPI apps and found Google Tez, the most convininent, user friendly, easier to use, trustable payments app. It is very easy to link the bank account details as the app provides step by step guidance and once the bank account is linked with the app, we can even find out who in our contacts list is using the Google Tez app and the app automatically saves them in the payments list. It is also a very trusted app as it comes from Google and Im relax that my transaction data is safe. In short , Google Tez is a fast and safe method to transfer money.
