This is why everything apps are so popular in many parts of the world. Using a mini-app from the internet running within another app is far preferable to downloading a whole app you may never need to use again. The way they do it in China is so seamless even if you've never visited the business before. There's never any special account creation or entering of payment information.
Obviously it's pretty terrible in terms of user privacy since the everything app has basically unchecked access to all of your personal information and habits, but the convenience is incredible and feels decades ahead of how apps work in the US.
