Peptide Tracker is the simplest way to stay on top of your peptide protocol — schedule, doses, and supply, all in one place — and actually stick with it. Pick a peptide from the built-in library to add it in seconds, then set your own schedule and dose. Tap when you inject, and get a gentle reminder when the next dose is due. No spreadsheets, no guessing when you last injected. WHAT YOU CAN TRACK - A built-in library of 30+ peptides — GLP-1s like semaglutide and tirzepatide, BPC-157, TB-500, testosterone, HCG, growth-hormone peptides, and more - Titration ladders — build your own dose-escalation plan and get a reminder when it's time to step up - Reconstitution calculator — enter your vial strength, water, and dose to see the units to draw on an insulin syringe - Supply tracking — doses left, a "use by" date, and a heads-up when it's time to reorder - Not in the library? Add any custom peptide yourself STAY CONSISTENT - One-tap logging — just hit "Injected" - A countdown timer to your next injection - Push notifications so you never miss a dose - Dose, injection site, and notes saved per peptide - Your full injection history at a glance - On/off cycles, pause anytime, or auto-finish after a set number of injections MAKE IT FUN, NOT A CHORE - Earn XP every time you log a dose, and level up as your protocol runs - Unlock 56 achievements in bronze, silver, and gold — for landing doses on schedule, rotating your injection site, sitting out your own off weeks, and finishing the course you set - Take on a rotating board of daily, weekly, and monthly challenges, built from your own schedule and never asking for more than your plan already does - The Progress tab shows your adherence, how often you're on schedule, and a 90-day trend for every protocol PRIVATE BY DESIGN Everything stays on your device. No account, no sign-up, no data collection. Set it up in under a minute and stay consistent without overthinking it. Peptide Tracker Pro unlocks unlimited peptides and the reconstitution calculator — available as a monthly or yearly subscription, or a one-time lifetime purchase. The free version covers one peptide with full scheduling and titration. Questions or ideas? Hit the contact link in Settings and I'll get back to you fast. Peptide Tracker is a personal logbook and reminder. It does not provide medical advice and does not recommend or calculate doses — you enter your own, from your prescription or protocol.
