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. StackFlow is built for people who take supplement routines seriously. It is not medical advice, diagnosis, or treatment.

Stack turns your supplement routine into a living shelf you can read at a glance. Add what you take and set when you take it. Each item sits on your shelf as its own bottle. It glows when a dose is due, dims when you've taken it, and empties through the day, refilling each morning. One look tells you what's left and what's done. No checklists to read. PRIVATE BY DESIGN Your routine syncs privately through your own iCloud — never our servers — so it follows you to a new device. No account, no sign-up, no ads, and nothing is ever sold or shared. Your routine is yours. NEVER MISS A DOSE Reliable reminders for every dose time, gentle nudges if one slips, and a Home-screen widget showing your next dose at a glance. EVERYTHING IN ONE PLACE - A living shelf that shows your whole routine at a glance - Add anything you take, with your own names, forms and notes - Flexible schedules: multiple times a day, specific times, or days of the week - One-tap check-off and a countdown to your next dose - Adherence stats and streaks to keep you consistent - A full intake history - Pause anytime, or mark something finished Stack is a reminder and logging tool, not medical advice. Set it up in under a minute and let it keep your routine on track. Stack Pro unlocks every feature.
