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. 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: $79.99 USD / year (best value) Subscriptions auto-renew unless cancelled at least 24 hours before the period ends.

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

Biohack Tracker is a private log for the protocols, supplements and medications you already use. Set reminders on the days you choose, tick each one off in a tap, and keep a site-rotation log for prescribed injectables. Import your blood tests to see every marker against its reference range over time, and sync sleep, HRV, resting heart rate and workouts from Apple Health. Biohack Tracker is a tracking and education tool. It is not a medical device and does not sell, source, recommend or dose any substance. WHAT YOU CAN DO • Today: what's due, what's done and your Biohack score at a glance, with one-tap "Mark taken". • Protocol log: log protocols, supplements and medications by route with colour-coded icons, set reminders on the days you choose and see your adherence. • Site rotation: numbered body sites with rest rings that show how recently each was used, plus a general rotation guide to use alongside your prescriber's or pharmacist's instructions. • Blood tests: import a PDF or photo. Each marker is shown against its reference range and trended, with "worth discussing with your GP" patterns and retest reminders. • Sleep, recovery and training: sleep stages, HRV, resting heart rate, breathing rate, blood oxygen and temperature from Apple Watch, Oura, Whoop, Garmin and more, plus workouts (including sessions synced from Strava or Runna) and your Runna plan. • Scores: a Vitality score from your labs and a Wellbeing score from your last 7 days combine into one Biohack score, with ways to improve. A guide to your own trends, not a medical assessment. • Templates and library: educational routine templates (no doses) and a reference library of 215 supplements and compounds with evidence levels, safety flags and legal status. • Biohack coach (Pro): ask about your own data. The coach can build a simple 4-week habit plan from a result, show the before and after when you retest, answer questions about a photo of a meal or label, and remembers what you tell it (see or clear it any time). General guidance only, never dosing or diagnosis. AI features run only after you allow them. • Clinician-ready reports, progress photos and metabolic health. PRIVACY Your data is stored in your private account and encrypted in transit and at rest. We never sell your data or use it for advertising, and your health data is never used to train AI models. Apple Health data is read-only. Download all your data or delete your account at any time. LIFETIME UNLOCK & PRO Free to download. A single one-time purchase (A$4.99, no subscription) unlocks all tracking: protocols and reminders, site rotation, sleep and recovery sync, templates, blood test import, charts, progress photos, metabolic health and retest reminders. Pro adds the AI layer and includes the unlock: the Biohack coach, 4-week plans, blood test and protocol analysis, trend projections, clinician-ready PDF export and the weekly digest. Pro is A$7.99/month or A$79.99/year. After the unlock you can ask the coach 5 questions and run 1 blood test analysis free. Fair-use limits apply to AI features. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions auto-renew unless cancelled at least 24 hours before the period ends; manage or cancel in your device Settings. IMPORTANT Biohack Tracker is for educational and organisational support only. It is not a medical device, does not diagnose, treat, cure or prevent any disease, does not prescribe or recommend doses, and is not a substitute for professional medical advice. Wearable readings are device estimates. Always check with your doctor before making health decisions. In a medical emergency, call your local emergency number.
