# Dose — Peptide Tracker > The private, all-in-one peptide tracker for people who take their protocols seriously. ## What is Dose? Dose is an iOS app for tracking peptides, TRT, GLP-1s, and other compounds. It replaces spreadsheets, notes apps, and guesswork with a purpose-built tool designed around how people actually run protocols. All data stays on your device — no accounts, no cloud, no data collection. ## Who is it for?
