Track your peptide protocol with Cal-AI-style clarity. Log doses, scan meals with AI, get weekly insights, and export PDF reports — all private, all local.
Peptidly is a private, research-informed tracker for people following a peptide protocol. Built for clarity, privacy, and serious tracking — not dosing advice.
WHAT YOU CAN DO
• Log every dose with body-map site rotation — never double up on the same spot
• Track weight, hydration, sleep, and symptoms alongside your doses
• Scan meals with AI — take a photo, get macros instantly
• See AI-generated observational correlations across your own data
• Browse 60+ peptide reference profiles with mechanism, half-life, and published research
• Ask Pep Bot — an educational chat that explains terms and declines dosing questions
• Export polished PDF reports for your physician
• Unlock 4 premium themes (Forest, Midnight, Sunset, Mono)
DESIGNED FOR PRIVACY
• Everything lives locally on your device
• Optional iCloud sync uses your own private database
• No accounts, no sign-in, no tracking, no ads
• Face ID app lock included
• One-tap delete erases all data
WHY PEPTIDLY
Most tracking apps bolt peptides onto a generic fitness shell. Peptidly was built peptide-first. Every screen — from site rotation, to vial inventory, to the research library — assumes you already take this seriously. And because we believe health apps should never replace clinicians, we explicitly refuse to give dosing advice anywhere in the app.
PREMIUM
Unlock the meal scanner, AI insights, Pep Bot, premium themes, and PDF export with a single annual subscription.
3-day free trial, then $35.99/year. Cancel anytime in Apple Account Settings. Subscription auto-renews annually.
IMPORTANT
Peptidly is a personal record-keeping and educational reference tool. It does not provide medical advice, diagnosis, treatment recommendations, or dosing instructions. Always consult a qualified healthcare professional before starting, changing, or stopping any peptide, medication, or supplement.
