A location based app that gives the social status & brief bio of the people nearby. Like if they were at a fancy party, it could tell them if a movie star or a forbes 400 member was there.
An app that uses your chosen or GPS location to point out nearby Michelin rated and other high end restaurants and amenities.
When with a group of other likewise wealthy people using the same app, you all "swipe left or right" the suggested food styles (pizza, Japanese, French, Michelin Starred, etc), and it returns info and links to the restaurants that fit what most of the group agree upon.
Of course everyone gets to rate the experience after. Something that is valuable to the businesses as well. Maximize!
Being not wealthy and haven't diner before at a Michelin rated restaurant, could lead to the assumption "I want it now and I can afford it, so I go and get it" is what the life of a rich men is - but, all of the Michelin rated restaurants are booked out for the next weeks and months. Just thinking of el bully: "we're booked out for the next 2y. Would you like to make a reservation in ... September 2034?" :)
So, this won't work out as imagined.
Also not all Michelin rated (and otherwise great) restaurants have years-long waiting lists. They exist, but you are pretending they are all that are available to the wealthy. Not all of them are even that expensive - wealthy people go for the best and/or most reputable of everything, which tend to be expensive, but are not always. They don't automagically gravitate to the exclusively expensive just for expense's sake. That, my friend, is the imaginations of "the poor."
You obviously missed out on "Pizza" being included in my list. Rich old people might not like it, but rich kids like it BIG TIME. Hell, Drake is rich, and his favourite resto according to those videos, is a cheap Chinese hole in the wall (it's actually pretty good, but it is cheap).
Your first sentence, and subsequent meandering pretends that you know something others don't. You obviously don't. And that's okay.
It was a point against the "app for the rich" + "to point out nearby Michelin rated and other high end restaurants and amenities." in the context of suggestions for app features.
There's also a pizza in this context.
So, why would Drake use the rich-people-app if he loves eating in a hole in the wall and can order doordash to be delivered food from that hole? You see your misthinking now? If it's not exclusive, then there's already a solution for. If it's exclusive, then it's restricted and not in the abundance.
But that's ok, too. I don't care about the wealthy, because they're not on my wavelength at all. And that's also not my biggest aim in life. If you're surrounded by them, enjoy!
but it's still a good idea
An app to stalk famous people is what poor people are interested, not rich.
