There is an app for almost anything. Using applications is second nature, so it is no wonder that banks also use apps. However, banking apps require much more care when being developed.
Unstable banking apps have severe consequences:
Customers can lose trust in the app if it crashes when a user attempts to make a purchase.
Financial losses due to crashes during transactions can dampen brand reputation and cause users to abandon the app, especially with so many payment applications in the market.
Crashes may also result in severe non-compliance with industry and government regulations.
