Log your peptide protocol in seconds. Doses, vials, reconstitution math, hydration, and weight in one private on-device logbook.
PepLog is a private, on-device logbook for people who manage a peptide protocol and want to actually remember what they did.
It's built around one idea: recording a dose should take seconds, right after you take it, the way a food tracker works. Your health data stays on your device. There's no account and no login.
WHAT YOU CAN DO
• Log a dose in a couple of taps: amount, time, injection site, and a note
• Track your vials: enter a vial's contents and the water you added, and PepLog derives the concentration and shows how much you have left as you log
• Set reminders on your own schedule and see what's up next right on Home
• See your consistency: a logging streak, badges, a week view, and a history of everything you've recorded
• Track your weight and hydration over time, with your own optional goals
• Measure: a unit converter that turns the numbers you enter (vial amount, water, your dose) into syringe units and volume
• Vial history: every finished vial kept as a permanent record
PEPLOG PRO PepLog is a subscription app. New members choose a yearly plan with a 7 day free trial, or a monthly plan. Prices are always shown in the app before any purchase, payment is handled by Apple, and you can cancel anytime in your App Store settings. Installed before version 1.2? Your access stays as it was.
PRIVATE BY DESIGN
• No account and no login
• Your health data never leaves your device: doses, vials, weight, and hydration are stored locally and are never uploaded
• Subscriptions are processed by Apple. Our subscription partner receives only an anonymous identifier and purchase status, never your logs
• No ads, no data sale, no third party analytics
PepLog is a logging and measurement tool. It does not provide medical advice, dosing recommendations, or treatment guidance, and it does not recommend or endorse any substance. Always consult a qualified healthcare provider before starting, stopping, or changing any regimen. For adults 18+.
