Peptide Tracker is used by over 100,000 people. Track peptides and GLP-1s in one app. Build your stack, log every dose, manage vials and supplies, monitor injection sites, visualize estimated plasma levels, sync Apple Health, follow your progress, and connect with people using the same compounds. Whether you’re managing one compound or a complex stack, keep your schedules, dose history, and inventory organized in one place. TRACK YOUR PROTOCOL Build Your Stack Create protocols with custom doses, schedules, frequencies, and durations. Add common peptides in seconds or create your own custom compounds. Log Every Dose Record scheduled or past doses, add notes, track injection sites, and edit entries anytime. When you correct a dose or change the vial it came from, your inventory updates automatically. Manage Vials and Supplies Keep track of mixed and unmixed vials, remaining volume, blend components, bacteriostatic water, and other supplies so you always know what you have on hand. See Your Estimated Levels Visualize how each compound builds and fades over time with an estimated plasma level curve based on your logged doses and the compound's half-life. Stay on Schedule Optional reminders help you stay consistent. See taken, skipped, and missed doses at a glance, follow your week with a simple checklist, and watch your consistency build a night sky you can share. FOLLOW YOUR PROGRESS Sync Apple Health Connect Apple Health to see your weight and body measurements, blood pressure, resting heart rate, HRV, sleep, steps, active energy, and nutrition in Pulse, on the same timeline as your doses. Peptide Tracker only reads from Apple Health and asks your permission first. Connect it from Settings or from Pulse. Track Your Weight Log your weight over time, follow the trend, and see your progress alongside the protocols you're running. Compare Progress Photos Take consistent progress photos with alignment tools that help you match your framing each time. Browse your photos by month, compare any two side by side, and share the result. Review Your History Browse your complete dose history in a calendar and quickly see what you took, when you took it, and which protocol it belonged to. CONNECT WITH PEOPLE ON THE SAME COMPOUNDS Ask questions and hear from people who have actually used the compounds you're researching or tracking. Share your own experience through structured answers, reply directly to others, and continue the conversation in open threads with quotes and mentions. Everyone participates under a username rather than a real name, with reporting, blocking, and community notes built in.

ReceptionRating · Positive reviews · Number of ratings

Peptide Tracker Log & Reminder holds the better App Store score, 4.9 against 4.3. That said, the two scores are not equally well evidenced: Peptide Tracker Log & Reminder has 3K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 95% of Peptide Tracker Log & Reminder's written reviews are positive against 100% of Peptide Injection Tracker's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Peptide Tracker Log & Reminder ships an update every 4 days, Peptide Injection Tracker every 3 weeks. The most recent releases landed on November 11, 2026 and October 31, 2026 respectively.
