Track. Schedule. Never miss a dose. PepTracker is a dose log and protocol tracker built for peptides, GLP-1 medications, and testosterone. Create structured protocols, schedule injections, calculate exact syringe volumes, and keep a clean record of your progress in one simple app. What you can do with PepTracker • Log doses, not guesses – Track every injection with an easy dose log instead of notes or spreadsheets. • Build peptide and GLP-1 protocols – Create schedules for Semaglutide, Tirzepatide, Retatrutide, BPC-157, AOD-9604, TRT, and more. • Use the built-in dose calculator – Enter vial amount, diluent volume, and target dose (mg or mcg) to get the exact mL or insulin-syringe units to draw. • Stay on schedule – Get reminders for upcoming doses and see what’s due today on the Home screen and in the calendar. • Track progress over time – Log weight and other metrics to see how your protocol is trending. Made for real protocols PepTracker works well whether you’re: • Running a GLP-1 weight loss protocol (e.g., Semaglutide, Tirzepatide). • Managing peptide stacks for recovery, performance, or wellness. • Keeping a consistent TRT schedule and dose history.

Verdict
The clearest difference is price: PepTracker at Free against PeptideJournal's $5.99. PepTracker also leads on rating (4.7 vs 4.3) and ratings volume (413 vs 20). PeptideJournal's advantage is in-app purchases (none vs 2) and update cadence (weekly vs every 2 weeks). On ads, device support and iOS requirement there is nothing between them.
