# Best Peptide Tracker Apps in 2026: Features, Pricing and Picks

An editorial guide to eight peptide and GLP-1 tracking apps: what each one does well, what it costs, where it runs, and who it suits.

## Quick answer

There is no single best peptide tracker for everyone; the right app depends on what you track and what else you need from it.

For a free tracker with no subscription, Peptide Tracker (Flat Six Labs). For a prescribed GLP-1 medication, Shotsy. For nutrition alongside a GLP-1 routine, Pep AI. For wearable data next to your log, PeptIQ. For private, detailed vial records on iPhone, Peptide Tracker & Calculator. For AI help setting up protocols, PepTracker. For several protocols side by side with on-device storage, PeptidePal.

For peptide research and vendor price comparison in the same app as your tracker, Peptide Library, which publishes this guide.

## Picks

- Best for peptide research: Peptide Library. The only app here with cited research profiles plus publication and clinical-trial statistics.
- Best completely free tracker: Peptide Tracker Log & Reminder. No subscription or paywall, on iPhone, Android and the web.
- Best for GLP-1 medication tracking: Shotsy GLP-1 Tracker. Built for GLP-1 injections and pills, with medication-level estimates and reports for care teams.

- Best for vendor price research: Peptide Library. The only app here that lists vendors and compares price per mg within each product form.

## How we compared

We read each app's US App Store listing (description, release notes, In-App Purchases and privacy label), its Google Play listing where one exists, and the developer's own website, on October 25, 2026.

A feature counts as present only when one of those sources states it. When no source mentions a feature we write "Not advertised", not "No"; we write "No" only when the developer says a feature is absent or was removed. Where sources disagree, we say so.

We didn't install or test competitor apps for this guide, and we don't score or rank them. The picks below follow from the documented features, and competitors win most of them.

Prices are US App Store prices. Several apps list more than one price per plan, so we show ranges; the price shown in the app is the one that applies.

App Store ratings aren't shown: they change daily and say little about whether an app fits your needs.

Facts about Peptide Library come from its own pages and store listings. Apps are listed alphabetically after Peptide Library; the order isn't a ranking.
