Flarestamina — 40-Day IELTS Challenge tracker is live

I launched Flarestamina (flarestamina.com) — a complete 40-Day IELTS Challenge tracker covering all four skills: Listening, Reading, Writing, and Speaking across 38 active days with 265 tasks. Users sign in with Google, check off tasks daily, and their progress auto-saves and syncs across devices in real time. The tracker includes a progress ring, a streak heatmap, and a class leaderboard. I also built a gated Teacher Dashboard that lets me add or remove days from the plan, view individual student progress, and track the leaderboard. The whole thing runs on vanilla HTML/CSS/JS with Firebase v10 (Auth + Firestore) loaded over CDN — no frameworks, no build step. Deployed to GitHub Pages with a custom domain at flarestamina.com. This is the first product I've shipped that other people can actually use to study. Building it taught me a lot about Firebase security rules, real-time sync, and shipping something that just works.
