Features
Read full description

PeptidePal is a peptide and GLP-1 protocol tracker used by over 150,000 people — dose logging, vial inventory, injection site rotation, reconstitution math, scheduling, and a 110+ compound library in one app. Whether you're on a prescribed GLP-1, running your first protocol, or managing several compounds on different schedules, PeptidePal keeps it all in one place. WHY PEPTIDEPAL? ◉ BUILT FOR PROTOCOLS, NOT PILLS: Generic medication apps track one pill, once a day. PeptidePal handles mcg, mg, IU and mL, cycles, on/off weeks, site rotation, and vial lifecycle. ◉ NO DRIFT: Three weeks in, it's easy to lose track of whether you're on day 9 or day 12. PeptidePal keeps the protocol you designed and the protocol you're running the same thing. MAIN FEATURES: ▶ PROTOCOL BUILDER Build from the library or from scratch. Set dose (mcg, mg, IU, mL), frequency (daily, every other day, twice weekly, 5-on/2-off, custom), days, start date, notes, and reminders. Run multiple protocols side by side. ▶ DOSE LOGGING & CALENDAR One tap to log. A week strip and monthly calendar show completed and planned doses, injection site, and time. Streaks keep you consistent. ▶ VIAL INVENTORY & SUPPLY ALERTS Log fill size, concentration, and expiry. PeptidePal projects each vial's run-out date from your live schedule and warns you about a week ahead. ▶ RECONSTITUTION MATH Enter vial size, diluent volume, desired amount, and syringe size. PeptidePal does the mg/mL arithmetic and shows it on a syringe diagram, with an over-capacity warning. Unit conversion only — PeptidePal does not recommend a dose. ▶ INJECTION SITE ROTATION Tap-to-select on an interactive body map, with recently used sites heat-mapped so your rotation is visible at a glance. ▶ COMPOUND LIBRARY 50+ profiles in plain English: mechanism, half-life, research status, reported side effects, and considerations. Every entry states its regulatory status. ▶ PROGRESS & LEVELS Weight and body-composition charts, progress photos with compare and time-lapse, and an estimated on-board level curve from your logged doses. Educational estimate, not a measurement. ▶ AI ADVISOR & COMMUNITY Q&A Short, plain-English answers to educational questions, plus a moderated peer forum. The AI will not recommend a dose, titration, or protocol, and routes medical questions to a provider. You're talking to an AI, not a clinician. Does PeptidePal work with prescribed GLP-1s? Yes — track Ozempic®, Wegovy®, Mounjaro® or Zepbound® with the same scheduling, rotation, and supply tools. Dosing decisions belong with your prescriber. Is my data safe with PeptidePal?

Verdict

The call

The clearest difference is ads: SpicyCalc at none against PeptidePal's shown. SpicyCalc also leads on rating (5.0 vs 4.7) and iOS requirement (15.1 vs 18.0). PeptidePal's advantage is ratings volume (4.9K vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.
