PepCal: GLP-1 Peptide Tracker
Dose log, vial math & levels
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
GLP-1 and peptide tracking that does the math: exact syringe units from your vial, medication-level estimates, supply alerts and site rotation. No account.
PepCal keeps your protocol organized, so you always know what's next, how much to draw, and whether you took it.
TODAY
- See your next dose with its syringe draw already worked out from your vial.
- Log in one tap. Supply is deducted automatically and the most-rested injection site is suggested.
- A week strip and your constellation, one star for every dose you log, show consistency at a glance.
STACK
- Schedule any compound: specific days, every N days, cycles (5 on / 2 off), different doses on different days, or titration steps.
- As-needed and reminders-only protocols.
- Pause, resume or end a protocol without losing history.
SUPPLIES
- Track vials (powder or premixed), pens (known strength or clicks), capsules and tablets.
- Enter what's in the vial and the water added, and PepCal shows the concentration and units on a U-100 scale.
- Low-supply alerts before you run out.
PROGRESS
- Adherence, dose calendar and history.
- Weigh-ins with a goal line, synced with Apple Health.
- A front and back body map for injection-site rotation.
- Progress photos that stay on your iPhone.
LEARN
- A plain-language course on the basics, and a compound library with safety information first and citations to published research.
PRIVATE BY DESIGN
- No account and no PepCal servers. Your data lives on your iPhone and syncs through your own iCloud.
- Apple Health data is never stored in iCloud.
- Face ID lock and CSV export.
