Keep every peptide and compound protocol organized in one private place — built for people who want a real system of record for their own tracking, not a generic pill reminder. PepX is a personal tracking journal that lives entirely on your device. Build your protocols, log each dose, run the reconstitution math, and watch your progress over time. No account. No login. No cloud. Just your data, on your phone. WHY PEPX • Purpose-built for peptides and compounds — not a one-size-fits-all habit tracker • Everything in one place: protocols, doses, inventory, bloodwork, body metrics, and photos • Private by design: your records stay on your device, protected by Face ID / Touch ID • Works fully offline — nothing to sign up for TRACK EVERY DOSE • Build multi-compound protocols with schedules, titration steps, and on/off cycling • Log doses fast — mark taken, skipped, late, or missed, and edit anytime • Discreet reminders that never reveal what you're tracking unless you choose to • Injection-site rotation with an interactive body map and next-site rotation reminders based on your own log DO THE MATH, NOT THE GUESSWORK • A general reconstitution & concentration calculator — does the math on the values you enter (no dose recommendations, not medical advice) • Convert between concentration, volume, and syringe units • Save and reuse your own calculations • Visualize estimated compound levels over time from published half-lives • A built-in reference list of compounds for your own record-keeping — for general information only, not medical advice — plus add your own entries SEE YOUR PROGRESS • Weight, body composition, vitals, sleep, hydration, and nutrition • Daily check-ins for mood, energy, sleep quality, and how you feel • Progress photos with side-by-side comparison and charts • Bloodwork and lab tracking with reference ranges over time NATIVE TO YOUR iPHONE • Home Screen and Lock Screen widgets for your next dose • Apple Watch companion to view and log doses from your wrist • Control Center, Action Button, and Siri shortcuts to log in a tap • Optional Apple Health sync across weight, body comp, vitals, activity, nutrition, hydration, sleep, and mindful minutes YOURS TO KEEP — OR DELETE • Export a clean PDF or CSV to share with your healthcare provider • Permanently erase all of your data, anytime, with one action • Available in English, Português, and Español PepX is a personal tracking and logging journal.
