The app, which includes a scientists category featuring figures like Lee Smolin and Max Tegmark, has sold one copy so far, and an Android version is expected in the coming weeks.", "body_md": "Hi, I made a simple picture quiz. You see a picture of a thing or a person and have to give the correct answer. I know, nothing fancy.\n\nMy initial idea was to just have scientists quiz with people like Lee Smolin, Max Tegmark (some “personal heroes”), etc. because I am huge fan of scientific interviews/content on youtube (my favorite channel is “Closer to Truth” with Robert Lawrence Kuhn) and I wanted to see if I know them all or get to know new ones.\n\nNow it contains many more categories but the scientists one is still the biggest.\n\nI am a developer for over 20 years. This is one of my first purely “vibe coded” apps. I mainly used Claude Fable and Opus (some GPT Sol e.g. for the app store screenshots).\n\nIt also turned into a halfway commercial product because it sells the full version containing all pictures and categories. So far it got 1 purchase... which was from a friend testing :p\n\nIt's hosted entirely on cloudflare (uses workers and durable objects). React 19, TypeScript 5.9, Vite 8, Capacitor 8, with native Swift/StoreKit. Android version is coming next weeks.\n\nHappy about feedback and maybe some nice reviews, should you enjoy it :)\n\nComments URL: [https://news.ycombinator.com/item?id=49542879](https://news.ycombinator.com/item?id=49542879)\n\nPoints: 1\n\n# Comments: 0", "url": "https://wpnews.pro/news/show-hn-who-or-what-is-it-a-picture-quiz", "canonical_source": "https://whoorwhatisit.com/", "published_at": "2026-09-02 21:33:13+00:00", "updated_at": "2026-09-02 21:52:13.800294+00:00", "lang": "en", "topics": ["ai-tools", "ai-products"], "entities": ["Lee Smolin", "Max Tegmark", "Robert Lawrence Kuhn", "Claude", "GPT", "Cloudflare", "React", "Capacitor"], "alternates": {"html": "https://wpnews.pro/news/show-hn-who-or-what-is-it-a-picture-quiz", "markdown": "https://wpnews.pro/news/show-hn-who-or-what-is-it-a-picture-quiz.md", "text": "https://wpnews.pro/news/show-hn-who-or-what-is-it-a-picture-quiz.txt", "jsonld": "https://wpnews.pro/news/show-hn-who-or-what-is-it-a-picture-quiz.jsonld"}}
