Peptidly is a private peptide tracker for people who track peptide protocols. It's a clean, distraction-free record-keeping app — not a coach, not a prescriber, just a place to log what you're already doing. Free, with no ads and no paywalls.
WHAT YOU CAN DO
▸ Peptide cycle planner
Plan peptide cycles with start and end dates, track day-by-day progress, and switch between primary and secondary cycles. Today's schedule on a single home screen.
▸ Compound & dose tracking
Add compounds to each peptide cycle. Record vial size, BAC water volume, dose amount, frequency, injection times, and notes. Built-in peptide library suggestions.
▸ Reconstitution calculator
Peptide reconstitution maths done for you — concentration, dose volume, syringe units. No more spreadsheets, no more guessing.
▸ Dose log & reminders
Mark each peptide dose as taken, missed, or skipped. Add injection site and notes. Site-rotation warnings (Strict / Loose / Off) help you avoid scarring and lipohypertrophy by flagging recently-used injection sites.
▸ Vial inventory
Each opened peptide vial is tracked separately — remaining mg, expiry date, low-stock alerts. The app knows when you run out and prompts you to open a new vial. Unopened in-stock count auto-decrements.
▸ Calendar view
Multi-day overview of doses across all your peptides, at a glance, with status colours.
▸ Offline-first & private
Everything works offline — log doses with no signal and they sync, encrypted, when you're back. No ads, no advertising trackers, no sale of your data. Export your data anytime.
▸ Sync & privacy
Cloud sync across devices. Optional biometric lock (Face / Fingerprint). Full data export. Delete-account flow with a 30-day grace period.
▸ Customisable
Display units (mcg or mg), 12h or 24h time, date format, reduce-motion mode. Every preference syncs across devices.
NOT MEDICAL ADVICE
Peptidly is an educational and personal record-keeping tool. It does not provide medical advice, diagnosis, or treatment. It does not recommend dosages or compounds. Always consult a qualified clinician before starting, changing, or stopping any protocol. You are responsible for your own health decisions.
