Pep AI is the GLP-1 tracker for shots, nutrition, side effects, weight, wellness, and everything in between. Track doses of Ozempic®, Wegovy®, Mounjaro®, Zepbound®, Foundayo®, semaglutide, tirzepatide, oral GLP-1s, and weekly injection routines.

Pep AI brings your routine together so you can stay consistent and understand your progress over time. TRACK SHOTS, DOSES AND INJECTION SITES • Log GLP-1 shots and doses • Give each medication its own dose schedule and reminder times • Track dose timing and history • Rotate injection sites with an interactive body map FOOD, PROTEIN AND WATER • Scan restaurant menus to compare meal options and see estimated protein, fiber and nutrition information • View an estimated GLP-1 Meal Score based on nutritional factors such as protein and fiber • Snap a photo of a meal for estimated nutrition and macros • Track calories, protein, carbs, fat and fiber • Quick Log meals and save frequently eaten foods • Log water and track hydration goals • Sync activity data with Apple Health • GLP-1 Meal Scores and nutrition information are estimates only and are not medical or dietary advice SIDE EFFECTS AND WELLNESS • Log nausea, fatigue, appetite changes and other symptoms • Track symptom timing and severity • See your symptoms alongside your dose history • Log energy and mood • Track sleep duration and quality PROGRESS • Track weight and trends over time • Add progress photos • Complete daily wellness check-ins • View your routine in a daily timeline • Earn achievements for staying consistent INSIGHTS AND REPORTS • View your tracking data in one dashboard • See patterns across nutrition, hydration, sleep, side effects and progress • View estimated medication levels and timing (estimates only, not medical advice) • Generate PDF reports to review with your healthcare provider WHY PEP AI Pep AI is built specifically for GLP-1 routines, giving you one simple place to stay organized and follow your progress.

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 Pep AI's 35%. PepOS also leads on ads (none vs shown) and rating (5.0 vs 4.7). Pep AI's advantage is ratings volume (4K vs 1) and update cadence (every 6 days vs fortnightly). On price, in-app purchases, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

PepOS holds the better App Store score, 5.0 against 4.7.

UpkeepUpdate frequency

Pep AI ships an update every 6 days, PepOS fortnightly. The most recent releases landed on November 5, 2026 and October 31, 2026 respectively.
