Pepti is the precision tracker for compounded GLP-1s, Retatrutide, and research peptides - with an AI Coach. Log every dose. Rotate injection sites across 12 zones. Read your bloodwork in context. AI COACH (Pro) Ask anything about peptide pharmacology: how compounds work, what a half-life means, and what published research says — every answer cites its source. The Coach explains the science with citations to published research. It never recommends a dose. Answers grounded in pharmacology and your logged history - not a generic health chatbot. Every response includes citations to published research. The Coach does not recommend personal doses; clinical decisions are referred to your healthcare provider. 12-ZONE INJECTION SITE HEATMAP (Pro) Track every injection across 12 anatomical zones - abdomen, thighs, glutes, delts. Pepti shows where you last injected and visualises rotation history. BLOODWORK READING (Pro) Upload your lab results and Pepti displays them against published reference ranges. The Coach explains what biomarkers mean - IGF-1, SHBG, hsCRP, testosterone, metabolic markers, liver function - referencing published research. WHOOP + APPLE HEALTH (Pro) Connect your WHOOP recovery data - HRV, resting heart rate, daily strain, sleep. Apple Health syncs steps, active calories, and HealthKit data. See how your logged compounds correlate with performance. PRIVACY BY DESIGN Your stack stays on your device. When using the AI Coach, your messages and selected app context are sent to Anthropic to generate responses; you must explicitly consent before any data is shared, and you can revoke consent at any time in Settings. No data sold. No ads. Built by an independent developer. THE COMPOUNDS THAT MATTER Compounded semaglutide, tirzepatide, retatrutide, GHK-Cu, BPC-157, TB-500, ipamorelin, CJC-1295, tesamorelin, NAD+, selank, semax, thymosin alpha-1 and more. WHO IT'S FOR Built for users managing their own peptide protocols - compounded GLP-1s, research peptides, TRT, or a full longevity stack. If you want a free shot-reminder app, better options exist. If you want a precision instrument and an AI with deep pharmacology knowledge, Pepti is built for you. PEPTI PRO (SUBSCRIPTION REQUIRED) The following features require an active Pro subscription: • AI Coach (with citations to published research) • Bloodwork reading • 12-zone injection site heatmap • Full compound library • WHOOP and Apple Health integration • Detailed progress analytics Pro Monthly: $12.99 USD / month Pro Annual: $49.99 USD / year (best value) Subscriptions auto-renew unless cancelled at least 24 hours before the period ends.

DISCLAIMER Pepti is a dose tracking tool. Not medical advice. The Coach provides general pharmacology education with citations to published research; it does not calculate, recommend, or prescribe medical dosages for individual users. Always consult a qualified healthcare provider before starting, adjusting, or stopping any compound.

Verdict

The call

The clearest difference is review sentiment: Pepti at 98% against Peptide Tracker's 50%. Pepti also leads on update cadence (every 2 days vs weekly). Peptide Tracker's advantage is rating (4.8 vs 4.0) and ratings volume (114 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Peptide Tracker sells 12 in-app purchases, starting at $7.99 per 7 days and Pepti sells 3 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Peptide Tracker holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Peptide Tracker has 114 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Peptide Tracker's written reviews are positive against 98% of Pepti's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Peptide Tracker ships an update weekly, Pepti every 2 days. The most recent releases landed on October 19, 2026 and October 16, 2026 respectively.
