Diem shows you one real historical event tied to today's date — but only the bright side: discovery, peace, culture, sport. No wars, no bad news, ever. Every event is written twice, in English and Croatian, not machine-translated. A Daily Challenge quiz ends your run on the first wrong answer, streak badges unlock new accent colors, and a home screen widget shows today's event without opening the app. Free to use, Pro unlocks the full calendar and extra colors.

Hey Product Hunt 👋 I work in emergency medicine, so a lot of my week is night shifts — the kind where the news feed is the last thing you want to open at 4am. I liked the idea of "on this day in history" apps, but every one I tried mixed in wars, assassinations, disasters — right next to the moon landing. So I built Diem to only show the good half: discoveries, peace, culture, sport. Nothing else. Every event is written twice — English and Croatian, by hand, not translated by a machine. There's a Daily Challenge quiz where one wrong answer ends your run, a streak system that unlocks new accent colors, and a home screen widget so most days you don't even need to open the app. Built solo with React Native / Expo. Thanks to Claude (Anthropic) for pairing with me through most of the development, and RevenueCat for handling subscriptions. Would love to hear what you'd want from a "positive history" app — more categories, deeper quiz, something else. All ears 🙏

I work in emergency medicine, so a lot of my week is night shifts. The last thing I want at 4am is a "this day in history" app that opens with a massacre. So I built the version I actually wanted.

A few things that make it different:
