The 'no-login' flow is a great way to reduce user drop-off. I tested the mobile-first design and it feels very snappy. One small suggestion for the UX: adding a PWA (Progressive Web App) manifest would make it even more convenient to use on mobile, as users could add it to their home screen like a native app. Great work on the interval reminders feature too!

Hi HN — I built PulseDaily, a simple mobile‑first habit tracker that runs entirely in your browser (no account, localStorage).

  It’s designed for “zero friction” daily check‑ins:

  - Add/edit/delete habits quickly
  - 3‑state daily check (none/partial/full) + momentum bar
  - Local backup/export
  - Interval reminders (browser notifications + optional beep sound), with customizable reminders
  - Starter templates you can import in one click: /templates

  I’d love feedback on the UX and what would make it actually stick for you (e.g., better onboarding, templates,
  reminder UX, export/import, etc.). If you try it, please tell me what felt confusing or missing.
