Paytm is most popular payment app in India. I used this app from last 3 years. This is trusted payment pltform.
User interface of this application is very user friendly. Design and layout of paytm is very nice. Users navigate and used this app easily.
Many features and function are avilable in this app. Users send and recieve money by mobile no. And QR code. Paytm gives Many cashbacks and offer. Payment transaction time is very fast. You can done transaction in few seconds. Once a transaction failed but paytm refunded my money in two hours.
User transfered money to his bank account easily.
So in my experience paytm is best payment app and very useful.
