Stack vs Peppy

Stack is the all-in-one tracker for peptides, GLP-1 medications, and TRT protocols. Log every injection, build custom dosing schedules, 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. • Reconstitution Calculator — Take the guesswork out of mixing. Enter vial amount, diluent volume, and target dose to get the exact mL or insulin-syringe units to draw. • 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.

Peppy is the peptide tracker that does the math. Log every GLP-1 and peptide dose, convert your prescribed mg into exact syringe units, organize your vials, rotate injection sites, and get gentle reminders so you never miss a shot. No account. No sign-up. Free to start. Peppy is a peptide tracker, logbook, and unit converter. It is not a medical device and it never recommends a dose. You enter the dose you and your provider already decided on; Peppy records it, converts the units, and keeps you organized and consistent. WHY YOU'LL LOVE PEPPY • No account, no sign-up. Open the app and start tracking in seconds • Your health data stays on your device and in your own private iCloud. Never on our servers • Built for GLP-1 and metabolic peptides, branded or compounded, plus custom peptides you add yourself • A peptide tracker with a clean, uncluttered design and a friendly mascot to keep things light • Thoughtful safety reminders at every step TRACK YOUR DOSES A peptide tracker is only as good as its log. Record every injection and see your full history at a glance: what you took, when, and what's next. Back-date a dose you forgot, spot missed doses, and build a streak week after week. CONVERT MG TO SYRINGE UNITS Enter your vial strength, BAC water volume, and prescribed dose. Peppy shows the exact units to draw on a U-100 insulin syringe, with a visual syringe fill to double-check at a glance. The formula is always shown so you can verify the math yourself, and built-in guardrails flag common mix-ups like mg versus mcg. ORGANIZE YOUR STASH AND VIALS Keep every peptide in one stash, track how much is left in each vial, and watch reconstitution and expiry dates so nothing goes to waste. Set up a new vial from presets in a couple of taps, and get a nudge when it's time to refill. ROTATE INJECTION SITES An interactive body map records where you injected and suggests your next site, so you rotate properly and never overuse one spot. NEVER MISS A DOSE Daily or weekly reminders that fit your routine and adapt as your schedule shifts. Titration-aware, so reminders keep pace as your plan steps up. Home Screen and Lock Screen widgets show your next dose and vial levels without opening the app. TRACK YOUR PROGRESS Log weight and symptoms alongside your doses and see clear trends in simple charts, so you and your provider can see how the plan is going. One peptide tracker for the whole picture. SAFETY FIRST Clear disclaimers appear throughout the app, every conversion reminds you to follow your provider's instructions, and the method is always visible so you can verify it. Peppy never recommends a dose, never sources or sells peptides, and never offers medical advice. Always follow the guidance of your licensed healthcare provider. PRIVATE BY DESIGN Your doses, weight, symptoms, and notes are stored on your device and, if you choose, synced through your own iCloud account. They are never uploaded to our servers, and there is no account to create. We collect anonymous, non-health usage analytics only if you opt in, and an advertising-measurement tool runs only if you allow tracking. See our Privacy Policy for full details.
