Any time we think about developing a smartphone device, there are some measures you need to bear in mind as a developer. But in this situation, if an app already exists that you would like to use as a kind of anchor or you would like to clone, then the testing measures would not be appropriate. When talking about how to make a website like PayPal you just need to remember the features, user experience and functionality of the PayPal mobile app. But what you need to do is clone the software in such a way that it’s the same in terms of features but looks different from outside. Will you agree with my view?
