I have variations of this conversation with our main UI guy from time to time (e.g. when he tries to add unnecessary features or buttons to an otherwise clean interface). He certainly understands design principles and is capable of adhering to KISS, but his opinion is that Chinese people actually like apps that attempt to do a gazillion things. For food delivery, I used to rely on Sherpas until it basically stopped working during our lockdown because I liked its simplicity. Then I grudgingly switched to Meituan and Eleme. At first, I was annoyed by all of their silly bells and whistles, but I soon decided that their true functional advantages were compelling enough for me to justify enduring their insane UI.

My take on map apps is a little bit different. I was interested in getting detailed subway maps (including station entrance numbers) last summer so I started using Amap more. But, after I figured out most of what I needed to know, I went back to Maps.me because its interface is much more to my liking. I still keep Baidu Maps and Amap as backups though. Google Maps isn't really an option on my (post 2021) Huawei. I still have it on some of my other devices, and it really is kind of behind the times. I honestly don't mind the Exploreshanghai app (I think there's also an Explorebeijing). It is ridiculously simple (e.g. subways only), but it does come in handy when I'm just trying to figure out where to transfer or what stations are most convenient.
