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 β€’ Custom Protocols & Stacks β€” Build your own multi-peptide protocols with flexible schedules (daily, weekly, every X days, or custom). Run multiple stacks at once, each clearly organized. β€’ Smart Dose Logging β€” Log every injection in seconds and see what's due today on your Home screen and calendar. A daily streak keeps you consistent. β€’ Vial & Refill Tracking β€” 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. β€’ Injection Site Tracker β€” Rotate sites with an interactive body map that remembers your recent spots, so you can avoid reusing the same area. β€’ Apple Health Sync β€” 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. β€’ Progress Photos & Compare β€” Capture progress photos and view them side by side with weight and date overlays. Hide weight for privacy, then share a branded comparison. β€’ Meal Scan β€” Snap a photo of your meal to estimate macros and keep nutrition alongside your protocol. β€’ AI Assistant β€” Ask questions about your active stacks and protocols in a private chat built into the app. β€’ Metrics & Insights β€” Clean charts and stats show how your protocol is trending over time. β€’ Home Screen Widget β€” See your next dose and stay on track without opening the app. β€’ Shareable Protocol Card β€” 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.

About

RuckMaxx

RuckMaxx is the rucking app. GPS tracking built for weighted walks β€” and a coach that tells you exactly how much weight to carry every week. Rucking is the military’s simplest training tool: put weight on your back and walk. It builds strength, endurance, posture, and mental toughness without wrecking your joints. RuckMaxx turns it into a program. TRACK THE RUCK, NOT JUST THE WALK Every session captures distance, pace, elevation, and time β€” plus the number other apps ignore: your load. Calories are computed with the Pandolf equation, the military research standard for load carriage, so a 35 lb ruck counts like a 35 lb ruck. YOUR COACH KNOWS THE LOAD Answer a few questions and RuckMaxx builds your weekly progression: how many rucks, how far, how heavy. Load work increases about 7.5% per week with a deload every fourth week β€” the way real programs are built. Beat the plan or miss a week, and it adjusts from what you actually did. BUILT FOR ALL LEVELS From your first 10 lb walk to veteran-level ruck marches. Choose your level and goal β€” get strong, lose weight, military prep, or simple consistency. STAY CONSISTENT Streaks, a 12-week consistency grid, and personal records: longest ruck, heaviest load, fastest mile. MORE THAN DISTANCE Weekly β€œruck work” volume (distance Γ— load), load-adjusted calories, elevation, pace trends β€” the numbers that actually measure rucking progress. APPLE HEALTH Every ruck saves to Apple Health as a workout, with calories included. RuckMaxx Pro is an auto-renewing subscription. Payment is charged to your Apple ID account. Subscriptions renew unless cancelled at least 24 hours before the end of the period. Manage or cancel in Account Settings.
