Staqc - Health & Supplement Tracker - Know which supplements work for you. Data, not guesswork.

Hey Product Hunt, I'm John, maker of Staqc. Built this because I was spending hundreds on supplements and had zero idea what was working. I was tracking in three different apps and still couldn't see the connections. Most people spend $100-300/month on supplements without knowing if they're actually working. Staqc's iOS app shows you what correlates with better energy, sleep, and health so you can make data-driven decisions and stop wasting money on what doesn't work. Track everything in one place. Supplements & Biomarkers: - Log supplements with dose, timing, and auto-reminders - Track biomarkers (labs) with reference ranges and trend charts - Upload lab PDFs (Premium) for automatic parsing - Set custom reference ranges to track when values fall outside optimal parameters How You Feel: - Energy, sleep, mood, symptoms—rate with quick daily check-in - Natural language: "bad migraine, 7/10, slept 5 hours" - Voice input option for low-energy days - Track any symptom: pain, fatigue, brain fog, focus—whatever matters to you Diet, Fitness & Life: - Food log with search and macro/micro tracking - Apple Health and Hevy sync (labs and workouts in same timeline) - Track stress, weather, life events—anything that might affect you - See everything on one timeline --- AI that works for you Natural Language Input: - Just type: "took vitamin D" or "energy 6/10 today" - AI understands conversational input—no forms, no complexity - Takes 30 seconds even when you're struggling - Start simple with 2-3 things; add more when ready Ask Your Data Questions: - "How has my vitamin D changed over time?" - "What correlates with my energy?" - "Did eliminating dairy help my symptoms?" - Answers cite YOUR actual logs, not generic advice Correlation Analysis: - Time series charts with supplements, diets, and events overlaid on biomarkers and effects - Correlation view with scatter plots showing strength and direction - List view ranking what correlates most with improvements - Time-lag detection catches delayed effects (e.g., "symptoms worse 48 hours after X") - First insight often in 2 weeks; robust patterns by 30 days Supplement Comparison: - Side-by-side analysis before buying something new - Ingredients, evidence quality, dosage recommendations - Interaction warnings with PubMed citations - Timing recommendations for absorption and synergy Real User Data: - Crowdsourced stats: "72% of users taking magnesium report better sleep" - Feed of real protocols and results—no ads, no sponsored content - Find people on similar health journeys and see what's working Learn From Others: - Compare your results to community patterns - See which supplements correlate most for users like you - Discover protocols you haven't tried - Share your discoveries (or keep everything private) Integrations: - Apple Health sync (automatic lab and workout import) - Hevy integration for fitness tracking - Future: Oura, Whoop, Eight Sleep (Q1 2026 roadmap) --- If you're wondering whether your supplements work: Track, see correlations, eliminate what doesn't help.
