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.

Verdict

The call

The clearest difference is review sentiment: PepOS at 100% against PeptIQ's 60%. PepOS also leads on ads (none vs shown) and rating (5.0 vs 4.7). PeptIQ's advantage is ratings volume (954 vs 1) and update cadence (every 5 days vs fortnightly). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. PeptIQ sells 10 in-app purchases, starting at $9.99 per 7 days and PepOS sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
