About

The Compound

Features
Read full description

You're already on a peptide protocol. What you need now is a tracker built for it — not another calorie counter. The Compound is built for people on semaglutide, tirzepatide, or retatrutide, whether you're getting pre-filled pens from a telehealth provider or working with compounded peptides. It handles everything generic health apps don't: titration schedules, injection timing, and side effect logging — all offline, all on your device. PROTOCOL ENGINE Set your compound and start date. The app calculates your titration schedule automatically — standard or slow pace — based on published clinical schedules. Every week you'll see your current dose, your next titration date, and what dose comes next. When life happens, you stay in control. Hold your dose for a week if side effects are rough. Titrate early if you're tolerating the current step well. Step back a dose if you need to. Switch between standard and slow titration at any point. When you reach your goal, enter maintenance mode — keep your dose weekly or stretch to bi-weekly injections. INJECTION LOG Tap once to log an injection. The app tracks every dose, timestamps each one, and tells you exactly how many days until your next shot — or flags it if you're overdue. Your full log is chronological, editable, and stays on your device. SIDE EFFECT LOG Log nausea, fatigue, constipation, vomiting, headache, and more — with severity and optional notes. Side effect history is charted alongside your dose progression so you can spot patterns. PROGRESS Weight, body fat, dose progression, and symptom history — charted over time against your protocol timeline. The data lives on your device. WHO IT'S FOR — Telehealth patients on Ozempic, Wegovy, Mounjaro, or Zepbound who want more than a paper schedule. — Self-administering users on compounded peptides who need a precise protocol tracker. — Anyone who wants a clinical-grade tool instead of a wellness app with motivational quotes. Note: retatrutide is Phase 3 and not FDA-approved. The app supports tracking it for research purposes only. The Compound does not provide medical advice. It is a tracking tool for people who already know what they're doing. $7.99/month or $54.99/year. No free tier. Your data stays on your device. Terms of Use: https://compoundprotocol.com/terms

About

PeptidePilot

Features
Read 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.
