I built a habit tracker for myself — friends loved it, so I shipped it to the world

I wanted to track my habits like a journal — with clear stats, charts, and streaks. But every app I tried either cost money, showed ads, or synced my personal data to some server.

So I built my own. In 2 weeks. Just for me.

Then I showed it to friends. They said it was genuinely useful and started using it daily. That's when I thought — if my friends find it helpful, maybe others will too. So I cleaned it up, added 11 languages, and shipped it.

What I built:

- Track habits with one tap, see streaks and heatmaps

- Works offline — all data stays on your device, always

- Export to PDF anytime

- No account, no ads, no subscription — free forever

- Installs like a native app (PWA) on any device

No VC money. No team. Just 3 weeks of building something I actually needed.

Just launched on Product Hunt — would love your feedback. What would make you use it every day?
