Klarjahr — The 0-Code Production App

Hey Product Hunt 👋 I'm Karsten, a Product Manager and father. On November 23rd, my kids went to bed, and I pushed my first commit to GitHub. On December 12th, Klarjahr went live on the App Store. 19 days. One person. One rule: no code written by me, only prompts to Google Gemini in those few hours I had each night after the kids were asleep. Here's what shipped: - Fully functional iOS app (all Swift generated) - Complete homepage + branding - Graphic design + icon (all AI-designed) - App Store submission, review, and approval Why I did this: I wanted to prove that the "coding barrier" is gone for everyone—even busy parents. Not because developers are replaceable, but because tools like Gemini let us turn intent into production-ready software in the "pockets of time" we have. The app itself: Daily affirmations + journaling for mental clarity. Simple, useful. But the real story: In 19 days of late-night prompting, I shipped something a dev team would usually take months to build (in the past). Does this resonate? Is this "after-hours" building the future of indie development? Thanks for checking it out 🙏
