StackDay 1.2 — AI Stack Builder, Research Hub & More AI-POWERED STACK BUILDER Build your personalized supplement stack in seconds. Answer a few questions about your health goals, diet, and activity level — and StackDay's AI recommends the perfect stack tailored to you. Covers vitamins, minerals, adaptogens, nootropics, peptides, amino acids, and herbal supplements. Complex blends now expand to show every ingredient inside. RESEARCH HUB WITH EVIDENCE RATINGS Explore 1,000+ supplements with evidence levels — Strong, Moderate, Emerging, and Preliminary. Each entry includes mechanism of action, dosing guidance, key benefits, and category. Research peptides like BPC-157 and TB-500, adaptogens like ashwagandha and rhodiola, nootropics like lion's mane and citicoline, and everything in between.

Add an entire protocol to your routine in one tap — great for beginners and optimizers alike. IMPORT & EXPORT YOUR STACK Back up your stack as JSON or share it with friends. Import stacks from other StackDay users to instantly replicate their protocol — perfect for coaches, biohackers, and health communities. SMARTER ONBOARDING New personalized onboarding asks about your sex, activity level, and dietary preferences to sharpen AI recommendations from day one. Vegan and vegetarian users get plant-based suggestions automatically. Athletes see performance-focused supplements prioritized. INTERACTION CHECKER IMPROVEMENTS Interaction warnings and synergies are now more visible throughout the app. The Smart Timing Optimizer helps you schedule doses to avoid absorption conflicts — like separating calcium and iron, or pairing vitamin D with K2. ENHANCED DAILY TRACKING Smoother check-off animations and a more responsive daily tracking experience. Cycling schedules, adherence streaks, and the 30-day heatmap all reflect your actual protocol in real time — including peptide cycles and custom day patterns. APPLE HEALTH & CORRELATION INSIGHTS Sleep, steps, and workout data from Apple Health power smarter correlation insights. See exactly how each supplement affects your energy, sleep quality, mood, and focus — backed by your own data, not guesswork.
