PepCore is a subscription app. A PepCore Premium subscription unlocks the whole app, and both plans start with a 7-day free trial. PepCore keeps a peptide protocol in one place — doses, schedules, vials, injection sites, cycles, labs and the reconstitution math — and keeps it on your own device. WHAT YOUR SUBSCRIPTION UNLOCKS • Build your stack — add peptides with timing, frequency, scheduled days and reminders • A Today screen that shows what is taken, skipped, overdue and upcoming • The full reconstitution calculator — vial size and bacteriostatic water to units and millilitres, saved per vial • A drawn syringe showing the exact mark to draw to • Injection site rotation with a visual body map • Cycle tracking (days on / days off) and dose titration schedules • A home screen widget with today's protocol at a glance • Streaks, adherence rates, spend and trends over time • Vial inventory with expiry alerts, plus supplier, batch and cost tracking • AI Coach — upload a blood work, InBody or Whoop screenshot and get an educational read in the context of the stack you're tracking. Educational reference only, never medical advice. • PDF and text reports to take to an appointment • A protocol QR image you can save or send • Backup and transfer to a new iPhone SOURCES AND REFERENCES Every piece of reference information in PepCore links to its published source — PubMed, NIH MedlinePlus, StatPearls and FDA drug labels — so you can read the original yourself. PepCore does not tell you what to take or how much. YOUR DATA • No account and no sign-in — nothing to register for • Encrypted on your device, with a Face ID lock • Export a backup file and move your data to a new iPhone over AirDrop • Your tracking data stays on your device. Nothing is uploaded unless you choose to use the AI Coach, which sends what you submit to an AI provider to generate that reading only.
