About

Stack

Features
Read full description

Stack is the all-in-one tracker for peptides, GLP-1 medications, and TRT protocols. Log every injection, set your own schedule, track your progress, and keep your full history organized in one private place. Built for adults working with a prescribing healthcare provider, Stack replaces scattered notes and spreadsheets with a simple, consistent system you control. You enter your own values (peptide name, dose, schedule, and sites) and Stack keeps them organized, reminds you, and shows your progress over time. FEATURES • Custom Protocols & Stacks — Build your own multi-peptide protocols with flexible schedules (daily, weekly, every X days, or custom). Run multiple stacks at once, each clearly organized. • Smart Dose Logging — Log every injection in seconds and see what's due today on your Home screen and calendar. A daily streak keeps you consistent. • Vial & Refill Tracking — Set how much each vial holds, watch it deplete with every dose, and refill in one tap. A tap-to-flip ring shows the exact percentage remaining. • Injection Site Tracker — Rotate sites with an interactive body map that remembers your recent spots, so you can avoid reusing the same area. • Apple Health Sync — Pull in weight, BMI, resting heart rate, HRV, sleep, steps, active energy, blood pressure, respiratory rate, body fat, lean mass, and VO2 max to see the full picture. • Progress Photos & Compare — Capture progress photos and view them side by side with weight and date overlays. Hide weight for privacy, then share a branded comparison. • Meal Scan — Snap a photo of your meal to estimate macros and keep nutrition alongside your protocol. • AI Assistant — Ask questions about your active stacks and protocols in a private chat built into the app. • Metrics & Insights — Clean charts and stats show how your protocol is trending over time. • Home Screen Widget — See your next dose and stay on track without opening the app. • Shareable Protocol Card — Generate a clean, branded card of your active protocol to save or share. PRICING Stack requires a subscription to unlock the full experience. IMPORTANT Stack is a personal record-keeping and organization tool for informational purposes only. It does not provide medical advice, diagnosis, or treatment, and is not a substitute for professional care. Always consult a qualified healthcare provider before starting, changing, or stopping any medication or protocol.
