Taking multiple supplements every day? The hard part is not remembering them — it is knowing what goes together, what needs spacing, and when each one works best. StackFlow turns supplement chaos into a clear, executable daily system. BUILT ON 200K+ REAL SUPPLEMENT PRODUCTS Search or scan real products with real ingredients, real serving sizes, and real label facts — not a generic vitamin list. INGREDIENT-LEVEL INTELLIGENCE StackFlow maps each product to its actual ingredients, so you understand what you are really taking — not just the brand name on the bottle. SCAN A LABEL, ADD IN SECONDS Point your camera at any supplement label. StackFlow reads the product, maps the ingredients, and places it into your routine. AI TIMING PLANS THAT EXPLAIN WHY Get timing suggestions based on ingredient interactions, absorption rules, and your current stack. Every recommendation shows the reasoning behind it. SYNERGY AND SPACING, MADE VISIBLE See which supplements work better together, which ones need to be spaced apart, and why your routine is organized the way it is. YOUR DAILY COMMAND CENTER Open StackFlow each morning. See exactly what to take now, check off each time slot, and keep your routine moving without guesswork. TRACK HOW YOUR BODY RESPONDS Log energy, sleep, digestion, and other signals. Over time, connect your routine to what you actually notice. DAILY INSIGHTS FEED (PRO) Receive a curated daily digest based on your stack, check-ins, and patterns — not a generic health tip, but intelligence about your specific routine.
