You should always keep a watch on before the app is launched, and another is all the time. An app analytics tool can help dev team hunt and destroy all the bugs that could bother users as they make their purchases. For the post-launch stage, make sure you have a reliable crash alerts tool, so that you will be made aware immediately if there is an unexpected performance problem with the payment screen.
If you think about it for a second, giving credit card details over the Internet is a little crazy. All it takes is allowing a hacker to someone’s bank account, could be emptied! That is why making sure that your payment SDK is secure and privacy-protected is just the first step. You can even display an icon indicating a secure connection – a green checkmark or a lock icon in the address bar. This will give your users an extra feeling of security.This can be solved by rigorous testing on your end – making sure that every device can display your payment screen correctly. With app analytics such as touch heatmaps, usability issues such as disappearing elements and unreadable screen margins are easily found. What you will want to find is whether users are failing to tap on buttons necessary for funnel completion, and where they are tapping instead.
