PeptidePal is a peptide and GLP-1 protocol tracker used by over 150,000 people — dose logging, vial inventory, injection site rotation, 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 AND 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. ▶ 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. ▶ NUTRITION TRACKER Stay on top of the nutrients your body needs in order to successfully manage your protocols. See what foods are beloved by the community. ▶ 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? Protocol data is stored on your device Progress photos are stripped of metadata before storage We do not sell your data or share health information with advertisers Delete your account and your associated data from Settings, in two steps.

Verdict
The clearest difference is ads: Peptides Calculator at none against PeptidePal's shown. Peptides Calculator also leads on review sentiment (55% vs 27%) and device support (3 vs 1). PeptidePal's advantage is rating (4.7 vs 4.3) and ratings volume (4.9K vs 177). On price, update cadence, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Peptides Calculator sells 10 in-app purchases, starting at $9.99 per month and PeptidePal sells 10 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.
PeptidePal holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: PeptidePal has 4.9K ratings behind it against 177, so its average is the more settled of the two. Written reviews complicate that: 55% of Peptides Calculator's written reviews are positive against 27% of PeptidePal's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 5 days. The most recent releases landed on November 8, 2026 and November 9, 2026 respectively.
