# Peptide Tracker

> Peptide Tracker is a free peptide tracking app for iPhone and Android, with no subscription and no paywall. It logs doses, sends reminders, calculates reconstitution, estimates plasma levels from each compound's half-life, and tracks vials, injection sites, weight, and progress photos. It covers GLP-1s such as semaglutide, tirzepatide, and retatrutide alongside peptides such as BPC-157, TB-500, CJC-1295, and ipamorelin, plus custom compounds and blends. iPhone users rate it 4.9 out of 5 on the App Store, across more than 1,500 ratings. This site also hosts a peptide reference library, free beginner courses, a help center, and free web calculators.
