Peptide Ledger: GLP-1 Tracker

Track your GLP-1 and peptide research without spreadsheets, scattered notes, or a monthly subscription.

Peptide Ledger keeps your plans, doses, vials, reminders, progress, labs, and research context in one private ledger. It shows the important things first, like your next dose, what's left in each vial, and when you'll run out. The full detail is always one tap away.

EVERYTHING IN ONE PLACE

• Build and follow your own plans
• Log doses, observations, check-ins, and milestones in a couple of taps
• Track open and sealed vials, lots, concentration, cost, and expiry
• See when each vial will run out and when to reorder
• Review doses, plan changes, inventory, progress, and labs in Timeline
• Import body weight from Apple Health when enabled
• Reminders, Home Screen and Lock Screen widgets, and supported Siri actions
