The only FREE peptide tracking app in the app store.
Stop juggling spreadsheets and notes. Peptide Tracker keeps your protocols, doses, vials, and injection sites organized in one place, built for adults running their own stack.
WHAT YOU CAN DO
Build Your Protocol
Create peptide protocols with dose, frequency, schedule, and duration. Edit anytime as your stack evolves.
Log Every Dose
Tap to log. Review your full history by day, week, or protocol. Never wonder "did I take it?" again.
Built-In Calculators
Reconstitution math, syringe draw volume, and half-life estimates based on your inputs, not guesses on a forum.
Track Your Vials
Concentration, remaining volume, and inventory at a glance. Know when you're running low before you actually are.
Smart Reminders
Optional push notifications for planned doses. Set it once and stop relying on memory.
Rotate Injection Sites
Visual body map to track where you injected last. Avoid hitting the same spot twice.
Your Data, Your Control
Export everything. Delete your account from settings. No spam, no selling your information.
WHO IT'S FOR
Whether you're running a GLP-1 protocol like semaglutide or tirzepatide, exploring research peptides like BPC-157 or TB-500, optimizing recovery and longevity, or managing TRT and HRT alongside your peptide stack. Peptide Tracker gives you one place to plan, log, and review.
Stop tracking your injections in the Notes app. Stop calculating reconstitution on the back of a napkin. Stop forgetting which side you injected last time.
Peptide Tracker is the dose log, vial inventory, injection site map, and reconstitution calculator built specifically for the way adults actually run protocols today.
Download free. Track your first protocol in under two minutes.
I’ve been on a peptide protocol for a few months now and was tracking everything in my notes app which was honestly a disaster. Missed doses, couldn’t remember which site I last injected, had no idea how much was left in my vials. Found this app and it genuinely solved all of it in one place.The vial inventory alone is worth it. I always know exactly what’s mixed, when I mixed it and how many doses are left. The injection site rotation feature is something I didn’t know I needed until I had it. And the reminders actually fire when they’re supposed to which sounds basic but other apps I tried were all over the place.It’s not trying to be a fitness app or a medical service. It’s just a clean focused tracker that understands what a peptide stack actually looks like. That specificity is what makes it work. Genuinely the first tool that fits how I actually run my protocol.
Greatest thing since sliced bread

I’ve been on peptides for about 6 months now, and honestly tracking them and remembering to do a specific one at a specific time was a nightmare. Missed doses, forgetting when and how I should do them. I’ve had this app for about a month now and man my routine has drastically improved. I HIGHLY recommend this app to anyone who is on peptides. I promise it will make things a lot easier for you
Changed the game for me

I was taking so many peptides and could not track anything. All the automations and everything really really helped me more than I can describe. This app is 10/10 and if you’re taking peptides you need to get this immediately.
This Could Be Great

This could be such a great app, but as a busy mom, it’s disappointing that I can’t backdate injections that I forgot to log. It renders the app useless to me. Also, it’s really hard to edit your vials after it’s been added. I ended up using a different amount of bac water than I originally planned for when I initially added the vial and I couldn’t edit it. I had to delete and start over. I love the interface and overall bright feel to the app. I just didn’t find it to be flexible or user friendly.
Developer Response
Thanks so much for this feedback, this is really helpful insight for us! I'll look into the backdate issue for past injections as well as the ability to make edits to your vials after they've been added. We'll get these changes in the next update in the next day or so.
- Log past doses directly from a protocol’s history.
- Edit vial details after creation, including label, diluent volume, dates, measurement scale, and notes.
- Vial setup is more flexible, with optional dates and clearer field-level errors.
- Depleted vials now remain visible in protocol supply history.
- Date and time pickers now apply selections when the sheet is dismissed.
- General reliability fixes and UX polish.
- Added support for unit-based dosing, including titration schedules and vial inventory tracking.
- Improved setup for peptide blends and premixed vials with clearer strength guidance.
