Stappn vs Stack

Stappn is a GLP-1 fitness coach and tracker for people building a movement routine alongside treatment. Whether you use semaglutide, tirzepatide or another prescribed GLP-1 medication, Stappn helps you plan workouts, remember injection days and see your progress in one place. WORKOUTS THAT ADAPT TO YOU Your AI coach uses your check-ins, recent activity and preferences to suggest a session for today. Follow guided movement videos, then tell the coach how it felt. Ask for a different movement, a lighter plan or an extra workout. As your routine develops, sessions can change in duration, rounds and difficulty. TRACK THE ROUTINE THAT MATTERS Set an injection day and time, log it and receive reminders. Track daily steps, weight and body measurements. Set an optional water goal and add glasses when you want to; water does not affect your streak. Review dated progress, completed sessions and the consistency you are building. TALK WITH YOUR COACH Check in about your energy, schedule and movement preferences. Your coach can use what you have done recently to suggest the next plan. Review the plan and request changes before starting. STAPPN PRO New users may start with a 7-day free trial. After the trial, continued access to coaching and personalized features requires an auto-renewing Stappn Pro subscription. Available plans, prices and renewal terms appear in the app before purchase. Stappn is a fitness and habit-coaching app, not a medical device. It does not provide medical advice, diagnosis or treatment. Follow your healthcare professional's guidance for medication and health decisions. Do not use Stappn for emergencies.

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.
