Pepti is the precision tracker for compounded GLP-1s, Retatrutide, and research peptides - with an AI Coach. Log every shot. 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 tells you what to take or how much. Answers grounded in pharmacology and your logged history - not a generic health chatbot. Every response includes citations to published research. The Coach does not give personal treatment advice; 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.

DISCLAIMER Pepti is a tracking tool for the shots you and your prescriber plan. Not medical advice.

Verdict
The clearest difference is ads: Peptidy at none against Pepti's shown. Peptidy also leads on iOS requirement (15.1 vs 17.2). Pepti's advantage is update cadence (daily vs every 4 days). On price, in-app purchases and device support there is nothing between them.
