Hi Product Hunt 👋 I built this because every fasting app I tried was a countdown timer with a streak badge stapled to it, and none of them told me what was actually happening in my body at hour 14. So the whole interface is one instrument. The dial isn't counting down — it's bound to metabolic phase, and the colour of the entire app warms then cools as you move from fed to fat burning to ketosis. Sal, the pixel salamander who lives on the dial, sleeps while you digest and glows once you're in ketosis. He's the phase indicator, not a sticker. Three things I'd point at: 🔥 The scoring stops at 24 hours, on purpose. End a fast early at 14h and you keep exactly what 14 hours were worth. Nothing in it pays you to skip more meals — a health app shouldn't be trying to make you sick. 🥗 Allergies and dietary rules (no pork, no alcohol, halal) are enforced rather than suggested — every generated meal is screened, and a week that breaks a rule gets refused, not shown with a warning. 🧭 The coach reads your actual data: your eating window, today's water, your last 14 fasts. Not general advice with your name on it. It runs in the browser — no app store, no account wall on your own data. It's free until 1 November 2026, then $3.99/month, and nothing asks for a card. Solo-built, self-hosted on one small VPS. I'd love to hear what's confusing or missing — I'm here all day.

It's Sal
