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.

The most complete protocol tracker for serious GLP-1 and peptide users. Track Ozempic®, Wegovy®, Mounjaro®, Zepbound® — or any peptide stack — with pharmacokinetic curves, a stack-interaction checker, and a citation-backed library no other tracker offers. PeptideCore is the private, on-device companion for GLP-1 patients, peptide stackers, microdosers, and biohackers who want a clean visual record of every shot, dose, and side effect. No ads. No data sold. No bro-science. Built by an iOS engineer who tracks their own protocol. FREE TO USE Log every dose, rotate injection sites, run the reconstitution calculator, and browse the peptide library — free, no account required. PeptideCore Pro is optional. WHAT YOU GET WITH PRO • Estimated medication-level curve. See how semaglutide, tirzepatide, retatrutide, or any peptide with a known half-life decays over the past week — with peak and trough markers. • Visual injection-site map. Front and back body view with 14 sites. Each site color-codes by days since last use so you rotate intelligently. • Dose-coded weight chart. Your weight line is colored by current dose tier so the weight loss response to your Mounjaro® or Wegovy® titration is visible at a glance. • Reconstitution calculator. Forward (dose → units), reverse (target draw → BAC water), and multi-peptide blend modes. Supports U-100, U-40, and tuberculin syringes. • Curated peptide library. 25+ entries with typical dose, half-life, route, and a tap-through PubMed citation. Covers BPC-157, TB-500, CJC-1295, Ipamorelin, MOTS-c, GHK-Cu, PT-141, Tesamorelin, and more. • Stack interaction checker. Flags overlap between active compounds with severity grading and PubMed-linked citations. • Inventory tracking. Vial-by-vial stock with expiry dates, reorder reminders, lot numbers, and cost per dose. • Live Activity countdown. Your next shot lives on your lock screen and Dynamic Island. • Apple Health integration. Pulls weight, HRV, sleep, and resting heart rate to correlate with your protocol. • Private on-device AI. Apple Intelligence flags adherence trends, symptom patterns, and site rotation balance — without sending your data anywhere. • Share card export. Render a branded progress card to celebrate weekly wins. SUBSCRIPTION PRICING • Pro Monthly — $12.99/month • Pro Yearly — $79.99/year (save 48%) Payment is charged to your Apple ID at purchase confirmation. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple ID account settings. PRIVACY-FIRST Your protocol data is stored locally and synced through your private iCloud account. We never sell, share, or send your data to ad networks. Apple Health is read-only. WHO IT IS FOR GLP-1 patients on Ozempic®, Wegovy®, Mounjaro®, Zepbound®, Rybelsus®, Saxenda®. Researchers logging BPC-157, TB-500, CJC-1295, Ipamorelin, Tesamorelin, MOTS-c.

Verdict

The call

The clearest difference is ads: PeptideCore at none against Pepti's shown. Pepti's advantage is update cadence (every 2 days vs every 3 weeks) and iOS requirement (17.2 vs 26.4). On price, in-app purchases and device support there is nothing between them.
