Stay consistent with the peptide protocol you already haveβ€”without spreadsheets, scattered notes, or guessing when your last injection was. Peptide Tracker brings your schedule, dose log, reminders, vial details, and progress together in one focused place. You enter your own protocol and doses; the app keeps them organized and never tells you what to take. SET UP YOUR PROTOCOL - Choose from a built-in library of 30+ options, including GLP-1s such as semaglutide and tirzepatide, BPC-157, TB-500, testosterone (TRT), HCG, growth-hormone peptides, and more; you always enter your own dose and schedule - Add any custom peptide that is not in the library - Schedule specific weekdays, every X days, or every X hours - Run on/off cycles, pause anytime, or finish after a set number of injections STAY ON SCHEDULE - See what is due today and count down to the next injection - Choose one, three, or five follow-up reminders - Log a scheduled dose with one tap, or record past and extra doses - Mark doses as injected or skipped and review past scheduled items KEEP A USEFUL HISTORY - Save amount, injection site, timing, and notes with each entry - Review your complete injection history by peptide - Track doses remaining and a vial use-by date - Use Home Screen widgets for today's plan, recent activity, and adherence MAKE CONSISTENCY REWARDING Every log builds XP and your level. Complete daily, weekly, and monthly challenges, unlock achievements, and follow your streak, adherence, on-time doses, injection-site use, 30-day activity, and 90-day trend. PRIVATE BY DESIGN Your peptide protocols and dose records are stored on your device. No account or sign-up is required. PEPTIDE TRACKER PRO Track one peptide with scheduling, reminders, logging, and progress. Peptide Tracker Pro unlocks unlimited peptides plus vial supply tracking with doses left and a use-by date. Available purchase options are shown in the app and may include an auto-renewing subscription or a one-time lifetime purchase. Payment is charged to your Apple Account at confirmation. Auto-renewing subscriptions renew unless canceled at least 24 hours before the end of the current period. Manage or cancel in App Store account settings. IMPORTANT Peptide Tracker is a personal logbook and reminder. It does not provide medical advice, diagnosis, or treatment; suggest or recommend doses, schedules, injection sites, or protocols; or replace a qualified healthcare professional. The presence of a compound in the library does not imply that it is approved, safe, or recommended for any use. Always follow guidance from your licensed healthcare provider.

The calm way to keep your injections on schedule. Log a shot in two taps, rotate sites without guessing and follow your dose steps, all in one private app. No account, no servers: everything you enter stays on your iPhone. WHO IT'S FOR ShotLog is for anyone who self-injects on a regular schedule prescribed by a doctor: weekly GLP-1 pens, testosterone, biologics, fertility protocols, vitamin shots and more. You enter the medication, dose and rhythm. ShotLog keeps track. ONE SCREEN, ONE ANSWER Open the app and see what matters: when the next shot is due, where the last one went and your current dose. No spreadsheets, no sticky notes, no "was it Wednesday or Thursday?" LOG IN TWO TAPS Date, dose and site are already filled in. Tap and you're done. Forgot to log? Add an earlier date anytime. ROTATE SITES WITHOUT GUESSING A body map shows how long each site has rested, from abdomen quadrants to thighs and arms. ShotLog suggests the site that has rested longest, so you don't have to remember. FOLLOW YOUR DOSE STEPS If your prescription raises the dose over time, enter each step and its number of weeks. The current step and dose update by themselves as the weeks go by. YOUR HISTORY AT A GLANCE A monthly calendar marks every shot as on plan, shifted or skipped. Tap a day to see the details. REMINDERS THAT DON'T NAG A heads-up the day before, a reminder on the day and a gentle repeat if you haven't logged. Missed a dose or paused your course? ShotLog adjusts without judgment. What to do next is a conversation for you and your doctor. PRIVATE BY DESIGN β€’ No account, no sign-up, no servers β€’ Your data stays on your iPhone. We never see it β€’ No ads, no tracking, no analytics on your health data β€’ Face ID lock, CSV export and delete-all in one tap FREE AND PRO Free forever: your course, two-tap logging, history, reminders, Face ID lock and CSV export. ShotLog Pro adds the site rotation map with next-site suggestion, the dose ladder by weeks and a reminder the day before your dose step changes. IMPORTANT ShotLog is a logbook, not medical advice and not a medical device. It does not recommend, calculate or change doses and does not interpret symptoms. Everything in the app is entered by you, as prescribed. Always follow your doctor's instructions and talk to your healthcare provider before changing your treatment.
