Afterglow

Track your mood daily. Understand yourself over time.

A minimal, private mood tracker that runs entirely in your browser — no app install required.

Features

• Daily grading — rate each day A+ through F with an optional note
• Calendar view — monthly and year-at-a-glance heatmap
• Statistics — grade distribution, mood trends, streaks
• Import — upload data from the official spreadsheet template
• Cloud sync — sign in with Google or Facebook to sync across devices (via Supabase)
• Guest mode — use locally without an account; data stays in your browser

Usage

Open the app at your GitHub Pages URL. No installation needed.

To use cloud sync, sign in with Google or Facebook. Any data you saved as a guest is automatically migrated to your account on first sign-in.
