PepTrack is for educational and personal tracking purposes only. It is not a medical device and does not provide medical advice, diagnosis, treatment, or dosing recommendations. All calculations operate only on values you enter. Always consult a qualified healthcare professional.
Inside PepTrack
Built for people who care about getting the details right — the math, the sites, the schedule, the trend. The polish of a premium app, none of the guesswork.
Enter your vial strength and your draw — PepTrack does the syringe math and shows the units on a clear, true-to-scale syringe. Your numbers, computed instantly.
Log every injection in seconds and rotate sites on a visual body map, so you always know what you did and where you did it.
A half-life visualizer that charts your logged injections over time, so you can see your pattern at a glance — built from the entries you record.
Sync with Apple Health to chart weight, body fat, and BMI. Watch the trend line, not the daily noise.
Build your own dose schedule and titration steps, get gentle reminders, and keep your next injection on the Home Screen widget.
Export a clean PDF or CSV of your history and walk into appointments prepared — no screenshots, no scribbled notes.
The math, handled
Reconstitution is where mistakes happen. PepTrack takes the values you enter — vial strength, fluid added, the dose you want to draw — and shows you the result on a clear, true-to-scale syringe. It's a calculator, not a coach: it never tells you what to take. It just does your arithmetic, precisely, every time.

Private by design
This is health data. We treat it that way. PepTrack stores your information on your device and, if you choose, in your own private iCloud — never on our servers.
Your log lives on your iPhone. Turn on iCloud sync and it stays inside your own private Apple account — opt-in, never required.
No sign-up wall. No ad networks. We don't sell your data, because we never collect it in the first place.
Optionally protect the app with Face ID, so your tracking history stays between you and your phone.
Summary for your provider
For your appointments
When your doctor asks how it's been going, you'll have an answer that isn't "I think okay?" Export a clean PDF or CSV — your injection history, sites, schedule, and weight trend — and bring a real record to the conversation. Better data makes for a better appointment.
Good to know
No. PepTrack never recommends doses, drugs, or protocols. The calculator only does arithmetic on the numbers you enter, and everything in the app is for educational and personal tracking purposes. Dosing decisions belong to you and your healthcare provider.
Yes. Your information is stored on your device, and optionally in your own private iCloud account. There's no required sign-up, and we don't sell or monetize your data.
