About the project
The challenge
We wanted a private, couple-shared habit tracker without forced sign-ups, monthly fees or third-party cloud sync.
What we did
Same stack as Hemma, we built Hemma first and reused PIN auth, Netlify Blobs and delta sync. Tabbed UI (Today, Days, Flow, Grow). Streak counter computed live on client. 3 days from idea to installed app.
The result
Per-user PIN login for couples
Streak counter and 7-day view
PWA, installable and offline-ready
3 days from idea to live (AI-driven)
