Hey Product Hunt! 👋
I built ChronoFast AI because every fasting app I tried was just a timer with a paywall. The moment that actually matters is 11 hours in, staring at a coffee, googling "does oat milk break a fast?" — so I built an app that answers exactly that.
What makes it different:
🤖 "Did I Break My Fast?" — type, speak, or snap a photo of anything you consumed and the AI analyzes its metabolic impact on your current fast stage.
📈 Metabolic Wave — an AI-simulated glucose/insulin curve for your fast (clearly labeled educational, not medical readings).
⌚ Your activity counts — steps, workouts, and sleep sync in. A fasted run literally moves you ahead metabolically; poor recovery tells the app to ease off nudges.
🔬 Science, cited — every fasting stage links to peer-reviewed sources (NEJM, the 2016 Nobel work on autophagy). No bro-science.
👥 Not alone at hour 16 — buddies, weekly challenges, live "4 fasting right now" zones, and a shareable weekly recap.
I'd genuinely love to know: what's the one thing your current fasting app annoys you with? I'll be here all day. 🙏
