New: PepLog accounts. Your subscription now follows you to any device, and rebuilt reminders never disappear. Your log still lives on your phone.
PepLog is a private 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.
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, with multiple times a day, and log or snooze straight from the notification
• 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
YOUR ACCOUNT, YOUR DEVICE
Your PepLog account exists for one reason: so your subscription is recognized on any device you sign in to. Sign in with Apple, Google, or an emailed code. No passwords.
Your log itself, your doses, vials, weight, and hydration, stays on your device and is not uploaded. You can delete your account at any time in Settings.
PEPLOG PRO
PepLog is a subscription app. New members choose a yearly plan with a 3 day free trial, or a monthly plan with no trial.

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+.
