Build with Macaron
Macaron, let's create a Coin Scholar app. I need a mini-app to manage my coin collection. Users can upload coin photos, input name, year, metal, and origin. It uses a fixed JSON list of 100 common coins with market reference prices, supports sorting by price descending, automatically flags coins over $100 as 「High Value」, and can export to CSV.
