People do not have motivation to rate and review even they have billions of experiences in total. Existing rating and reviews can be biased or scattered over single category focused apps, therefore it is very hard to reach meaningful information.
There are billions of experiences to discover;
7M+ movies and series
3M+ wines etc.
There are several rating & review applications focused on single category
iMDB, Rotten Tomatoes for movies & series
Vivino for wines
Booking.com for hotels
Trip Advisor for hotels, restaurants
Goodreads for books etc.
There are several social networks not focused on ratings
Instagram, express yourself by alluring photos or videos
TikTok, express yourself by entertaining musical videos
Twitter, express yourself by status updates etc.
There is no one-stop-shop application combining experience, personalization and earning.
