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.
