Peptide Injection Tracker is a focused, private way to organize your own injection records—without creating an account, seeing ads, or sharing a health profile. SEE WHAT'S NEXT Open Today for your next reminder, recent activity, weekly count, and a fast way to add an entry. A short setup checklist helps you add only the tools you want. LOG YOUR OWN RECORDS Record the peptide name, amount, unit, route, time, injection site, notes, and optional symptoms. Backdate entries when needed, then edit or delete them from your history. REVIEW ONE CALENDAR Build the schedule you already follow using selected weekdays or an every-N-days interval, a start date, optional end date, and pause/resume controls. Browse across months to see planned, completed, and missed occurrences. A same-day log completes the matching occurrence. The app does not supply a preset regimen. TRACK ACTIVE VIALS Enter a starting amount and your own low-supply threshold. Remaining supply is derived from matching injection logs, so editing, deleting, backdating, or changing a logged amount automatically reconciles the estimate. Optional expiry dates stay visible on the device. REVIEW SITE HISTORY Use the visual Sites screen to see when each location was last recorded. Color bands represent elapsed time only and do not provide medical guidance. KEEP YOUR RECORDS PORTABLE Review your full history for free. Pro adds PDF and CSV export, active-vial inventory, flexible schedules, and support for multiple peptides. REFERENCE TOOLS, WHEN YOU WANT THEM Open Settings to find the peptide library, amino acid reference, quiz, and general concentration tool. The concentration tool performs amount-per-volume unit math and does not calculate an amount to administer. PRIVATE BY DESIGN - Stored on your iPhone - No account - No ads - No analytics or tracking - Optional Face ID app lock Peptide Injection Tracker is for personal recordkeeping and educational reference only. It is not medical advice or a medical device, and it does not diagnose, prescribe, recommend, source, or verify any substance, amount, treatment, or protocol. Consult a licensed healthcare professional before making medical decisions. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
