Track. Schedule. Never miss a dose. PepTracker is a dose log and protocol tracker built for peptides, GLP-1 medications, and testosterone. Create structured protocols, schedule injections, calculate exact syringe volumes, and keep a clean record of your progress in one simple app. What you can do with PepTracker • Log doses, not guesses – Track every injection with an easy dose log instead of notes or spreadsheets. • Build peptide and GLP-1 protocols – Create schedules for Semaglutide, Tirzepatide, Retatrutide, BPC-157, AOD-9604, TRT, and more. • Use the built-in dose calculator – Enter vial amount, diluent volume, and target dose (mg or mcg) to get the exact mL or insulin-syringe units to draw. • Stay on schedule – Get reminders for upcoming doses and see what’s due today on the Home screen and in the calendar. • Track progress over time – Log weight and other metrics to see how your protocol is trending. Made for real protocols PepTracker works well whether you’re: • Running a GLP-1 weight loss protocol (e.g., Semaglutide, Tirzepatide). • Managing peptide stacks for recovery, performance, or wellness. • Keeping a consistent TRT schedule and dose history. PepTracker Premium (optional upgrade) Unlock more structure and flexibility for advanced protocols: • Unlimited protocols and peptide stacking in a single schedule. • Advanced scheduling options and extended calendar views. • Save calculator results directly into protocols. • Full protocol history plus mood and energy tracking. • Export logs to CSV/PDF and sync with external calendars (Apple and Google).

PepOS is the peptide protocol command center for biohackers who take optimization seriously. PepOS is an educational tracking and journal app. Not medical advice. Always consult a licensed healthcare provider before starting any peptide protocol. Track every dose, vial, and outcome. Build protocols by hand or let AI design them based on your goals. Close your daily rings — Execution, Progress, Recovery — and watch your 7-day optimization score climb. APPLE HEALTH + AI INSIGHTS Connect PepOS to Apple Health to see how your protocols are actually affecting your body. PepOS reads your weight, body composition, resting heart rate, HRV, and sleep data on your device and shows you trends alongside your peptide timeline. Weight entries you log in PepOS sync back to Apple Health automatically. With your separate permission, Peppy — our AI assistant — can also use a 30-day summary of your Health metrics to give protocol-specific insights ("your HRV has improved 14 ms since starting your current protocol") instead of generic advice. AI data sharing is optional, granular, and can be turned off anytime without disconnecting Apple Health. Your health data is never shared with advertisers and never used to train AI models. KEY FEATURES 260+ peptide library with detailed profiles, mechanisms, and educational dosing references Peppy — your AI peptide coach who knows your stack, your goals, and your history Smart protocol builder — manual, titration, on/off cycling, and transition planning Vial inventory tracking with cost-per-dose intelligence Injection site rotation across 8 regions with visual heatmap Daily check-ins for sleep, mood, energy, and side effects Blood work tracking with marker trends over time Progress photos with AI body composition analysis Weekly intelligence reports synthesized by AI Calendar sync, dose reminders, and protocol scheduling SUBSCRIPTION TIERS Free — 3 protocols, basic AI chat, 2 vials PepOS Intelligence ($9.99/mo or $59.99/yr, save 50%) — Unlimited protocols, unlimited AI, blood work tracking, AI blood analyzer, AI vial scanner, progress photo analysis, voice input, calendar sync, protocol sharing, transition planner, weekly intelligence reports, and priority AI Built by biohackers, for biohackers who don't settle for spreadsheets.
