PeptidePilot
Read full descriptionHide full description
PeptidePilot is a private journal for tracking peptide doses, schedules, inventory, and how each one makes you feel. No account, advertising, or tracking. WHAT IT DOES • Schedule recurring, multi-time, or as-needed doses with local notifications. • Track vials, premixed blends, pens, syringes, tablets, capsules, liquids, sprays, and more. • Reconstitution calculator with U-30, U-40, U-50, and U-100 syringe calibration. • Per-compound blend inventory and automatic reconciliation after edited or deleted logs. • Injection-site rotation — the app suggests the next site based on your history. • Side-effects journal — rate energy, mood, sleep, and GI on a 1–5 scale after a dose. • Insights — current streak, best streak, adherence over 7/30 days, and a simple chart of doses per day. • Correlation analysis — once you have a few weeks of ratings, see how each peptide changes your averages. • Cycle planner — set "weeks on / weeks off" and the app auto-pauses scheduling during off weeks. • Medals — quiet hex-shaped achievements for streaks, adherence, awareness, and rotation discipline. CATALOG A bundled, citation-linked reference of common peptides — what they are, half-life, regulatory status, references. Each entry shows a clear regulatory banner (FDA-approved prescription, compounded prescription, or research chemical). Adding any catalog entry asks you to acknowledge that status. PeptidePilot does not sell, ship, prescribe, recommend dosing, or replace medical advice. PRIVACY Your journal stays on your devices and, if you enable it, in your private iCloud account. There are no analytics, advertising SDKs, ads, or telemetry. Encrypted caregiver sharing and FDA checks are always user-controlled. EXTRAS • iPhone widget showing your next dose. • Live Activity / Dynamic Island countdown when a dose is imminent. • Apple Watch companion with next-dose sync and quick logging. • Siri Shortcut: "Log a peptide dose in PeptidePilot". • FDA recall center using the official openFDA feed, with MedWatch access. • Encrypted read-only caregiver passes that expire and can be revoked. • HealthKit (optional, read-only): authorized measurements, sleep, and supported medication context. • Backup & restore: encrypted JSON file saved to Files / iCloud Drive. • Face ID / Touch ID lock. • PDF & CSV export of your dose log. NOT MEDICAL ADVICE PeptidePilot is a journal. It does not diagnose, treat, or recommend. Consult a licensed clinician before starting, stopping, or changing any peptide protocol.
