Show HN: KarmaWall – A daily public wall for small productivity wins

Hey HN!

I'm a 17-year-old student building solo. I wanted to build a full app called WeekWise for habit building, but I don’t know mobile development yet. So I shipped one feature from it as a standalone web app: KarmaWall.

What it does: Every day, you just post one productive thing you did. That’s it. It's a small public wall to build daily consistency and feel accountable.

Why I built it: I often start strong with habits and then fade. I needed a simple nudge to stay on track — not private, but also not overwhelming. KarmaWall is a tiny step toward fixing that.

Built with: - Next JS + PostgreSQL - OTP based authentication - Desktop & mobile-ready

Try it: https://www.karmawall.space/

I’d love your thoughts. I'm planning to expand this into the full WeekWise app later, but I care most about helping people stick to small wins daily.

Thanks for reading!
