Peppy vs Pepty: tracker or peptide encyclopedia?

Pepty is a peptide app for iPhone, iPad and Mac that pairs protocol logging with an AI scan, a Learn course, an interaction checker and vendor price comparison under a Premium subscription, so pick it to learn and research. Peppy is a tracking-first iPhone app with 123 compounds, a body map, cycles and step-ups, Apple Health and no account.

Who each app is for

Peppy vs Pepty is tracking against learning. Pepty ("Pepty: GLP-1 & Peptide Tracker", by qlabs) calls itself "the leading peptide app with AI scans, source finder, price comparison, and an interactive Learn course". Its listing describes a library of 74+ compounds with benefit and safety details in 13 languages, an interaction checker, half-life charts for 30+ compounds, a reconstitution calculator, a site tracker and protocol logging with a calendar. It runs on iPhone, iPad, Mac and Vision. If you are early in your research and want a course, a reference and a scanner in one place, Pepty is built for that.

Peppy does one thing narrower and, we think, better: it runs your shots. Search one of 123 compounds, set a schedule, and the Today tab counts down to the next dose, the body map picks the site, the calculator gives you the units, and the check-in ties weight and side effects to dose day. It has no course, no AI, no vendor features, and no account. iPhone only.

Feature by feature

The table reflects Pepty's App Store listing and Peppy's app reference as of 2026-08-30. Pepty has no public website we could verify, so its store page is the source.

Learning tools. Pepty wins, and it is not close. Peppy's catalog entries carry a form, unit, typical frequency, dose ladder, half-life and a short description, which is enough to set up a protocol and nothing more. Pepty's Learn course, interaction checker and AI scan are a different product category.

Sourcing. Pepty includes a source finder and price comparison. Peppy deliberately has nothing of the kind and this site does not link to sellers. That is a real difference in what the two apps are for, not a missing feature.

Calculator and half-life. Both have a reconstitution calculator and a half-life chart. Peppy's calculator is free and inline in the protocol editor, so the units travel with the protocol, and warns when a dose will not fit a 1 mL syringe. Peppy's "Active in your system" curve (Pro) covers about 62 compounds versus Pepty's 30+. Always verify with your prescriber.

Site rotation. Pepty's listing mentions a site tracker tied to your logs. Peppy's Log shot sheet is a 13-site front and back body map that suggests the next site, shows "last used 6 days ago" and rotates across every protocol, free, with a heat-map (Pro). See injection site rotation.

Inventory, cycles, titration, Apple Health, export, widgets. None are listed for Pepty. In Peppy, Apple Health weight sync is free; vial inventory with a runs-out date, on/off cycles, auto-advancing dose ladders, PDF or CSV export and Lock Screen widgets are Pro. See peptide stack tracker for how a multi-compound routine looks.

Pricing

Pepty is free to download with "Pepty Premium" in-app purchases listed at $6.99, $9.99, $39.99 and $69.99. The listing does not say which period each price covers or what Premium unlocks, so check inside the app.

Peppy is free for one active protocol with logging, calendar, calculator, check-ins, site rotation, Apple Health and iCloud. Pro is $29.99 a year or $5.99 a week with a 7-day trial and adds reminders, insights charts, unlimited protocols, cycles and titration, inventory, photos, export and widgets.
