Hey Product Hunt 👋 I'm Daf, solo dev behind prtcl. Quick story on why this exists. A couple of years ago I strarted getting into health and longevity. The problem wasn't finding protocols. The problem was that I had no idea which of them were actually doing anything. Every habit tracker I tried made it worse. Red streaks the moment I skipped a day, dopamine-hit gamification, "you broke your 47-day streak" notifications that made me feel like I'd failed at being a person. None of them connected what I was doing to what was changing in my bloodwork or wearables. So I built prtcl which is more a lab notebook, not drill sergeant: 🧪 Fork curated protocols from the longevity space, or build your own from scratch 📊 Log adherence with weighted scoring (not every step matters equally) 📈 Track markers that matter to you: sleep, HRV, lipids, symptoms, whatever 🔍 Correlations engine surfaces which steps are actually moving which markers 🔒 Offline, no account, data stays on your device ❌ No streaks. No red failure states. No guilt. It's iOS first because that's where the biohacker crowd lives. Android will come if there's appetite. I'd genuinely love feedback. I built what worked for me and others I'm close to, It's flexible and powerful. I'm keen to hear if i did miss anything, if you want any particular health protocols tracked, or markers supported.
