    I built FlipCards – a flashcard app with variations to improve learning2025 · flipcardsapp.vercel.app · ▲42

    Hi HN, I’m Felipe, a 9-5 developer aiming to become a full-time indie hacker. I struggled with flashcard apps that focus on decorating cards instead of learning concepts, so I built FlipCards to solve that problem. What it does: FlipCards lets you: - Create cards for any concept (math, language, coding, etc.) - Add multiple variations per card – the more variations, the better your understanding - Study smarter – the algorithm randomly selects variations so you can’t just memorize Q→A patterns Why it’s different: - Most apps use reverse cards (Q→A, A→Q). FlipCards uses variations to…

    Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on.

  • I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
