Social feeds are broken. Everything lives forever, nothing feels urgent, and the algorithm decides what matters.
FlashFeed flips that.
Every post starts with a 24-hour countdown timer. Likes add time. Comments add more. Shares add even more. If your post gets ignored — it
self-destructs. Forever.
No ghost posts. No graveyard of old takes. Just a feed that stays alive and relevant.
What I built:
- ⏱ Real-time countdown timer on every post (Supabase Realtime)
- ❤️ Likes (+15 min), 💬 Comments (+30 min), ↗️ Shares (+45 min)
- 🔔 Push notifications before your post expires
- 🔍 User search + follow system + personal feed
- 📱 Installable PWA — works on iOS and Android

Built this as an experiment in ephemeral social — where attention is the currency and every post is a bet.
Would love feedback from the community — especially on the timer mechanics. Is 24h too long? Too short? What interaction should rescue a post the most?
