Best GLP-1 Tracker Apps in 2026: A Complete Comparison

For users prioritizing a no-account model and detailed injection-site rotation, OffGrid Dose is our documented fit. It keeps working data on the device and does not send health entries to a company-operated database. If you need Android support or built-in nutrition logging, Shotsy is a documented alternative; its account and storage model differs between iOS and Android.

Key takeaways:

• Best for no-account, detailed injection tracking: OffGrid Dose — on-device working storage and an eight-zone rotation map.
• Best for the narrowest documented company-access model: OffGrid Dose — no app account, company health database, or health-record uploads.
• Cross-platform free download: Glapp — publisher-documented access on iPhone, Android, and Web, with in-app purchases.

The GLP-1 medication tracker market has expanded rapidly. With millions of people now taking semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound), dedicated tracking apps have moved from niche tools to essential companions for medication management. But which one is actually the best GLP-1 tracker app for your needs?

This guide compares six GLP-1 tracker apps available in 2026. We evaluate published features, privacy disclosures, platforms, and current purchase descriptions to help you narrow the options. This is not a report of hands-on use.

How we evaluated these apps

This is a documentation-based comparison, not a hands-on test. On 2026-07-22, we checked the publishers' current app listings and privacy materials and followed Google's guidance for high-quality reviews. We compared supported platforms, account requirement, storage model, injection logging, weight tracking, export, and disclosed integrations. When a capability was not verified from current publisher documentation, we say so rather than infer it.

Commercial relationship: OffGrid Dose publishes this guide and sells OffGrid Dose, so we have a commercial interest in one product reviewed. Our product claims use the OffGrid Dose privacy policy and official listing; Shotsy claims use its platform-specific privacy policy and official listing. Official sources for every app are linked below.

Detailed Reviews

1. OffGrid Dose — Best for Privacy and Injection Site Tracking

OffGrid Dose requires no app account and has no company-operated health database, Firebase, or health-record uploads. Its working injection records, weight entries, progress photos, and side-effect logs use Apple's SwiftData framework on the iPhone. An Apple-managed device backup may include app data depending on your settings.

The app's standout feature is its visual body map with eight color-coded injection zones. The colors summarize logged site history and recency only. The map does not determine tissue readiness, safety, absorption, or effectiveness, and the app does not recommend an injection site. The competitor documentation reviewed did not describe an equivalent eight-zone status workflow.

Weight tracking places each logged titration step (for example, an entry changing from 0.25mg to 0.5mg of semaglutide) as a dated marker alongside weight entries. Reported side effects appear on the same timeline by date. This view organizes what you entered and when; it does not establish that a dose change caused a weight or symptom change. Progress photos are stored on-device with a before-and-after comparison slider and are not uploaded to an OffGrid Dose server.

The publisher describes a 10-second daily tracking flow, no app sign-up, and a local working health log. You can see the full feature list or read what makes OffGrid Dose different before deciding. Current access options are shown by Apple in the App Store and in the app.

Best for: Users who want a private GLP-1 tracker with no app account or company health-log database, detailed injection-site history, and on-device progress photos.

Limitations: iPhone and iPad only. No nutrition tracking. No oral GLP-1 support.

2. Shotsy — Best for Cross-Platform and Nutrition Tracking

Shotsy is a cross-platform GLP-1 tracker available on iOS and Android, with medication, weight, nutrition, and reminder features.

Shotsy is a free download with in-app purchases. Its current listing advertises injection reminders, site preferences and charts, weight logging, medication-level estimation, and Apple Health nutrition data on iOS. Check the current storefront for platform- and region-specific purchase options and feature gating.

Shotsy is one of the few GLP-1 trackers available on both iOS and Android, and it supports oral GLP-1 tracking for medications like the Wegovy pill. Its current privacy policy describes no app account and a private iCloud database on iOS, while the Android app uses Google Sign-In and Firebase.

Best for: Users who want a Mounjaro or Wegovy tracker with iOS and Android support and documented nutrition features.

Limitations: Its platform-specific cloud services and analytics disclosures may not suit users seeking a tracker without company analytics. The publisher documentation reviewed does not describe an eight-zone injection map comparable to OffGrid Dose's.

3. Pep — Best for Nutrition and Habit Tracking

Pep's current App Store and Google Play listings advertise medication and rotation tracking, meals, movement, symptoms, weight, progress photos, and charts on iOS and Android.

Pep is a free download with in-app purchases. Its current privacy policy says health entries remain local while optional accounts and product analytics support other app functions; check the current storefront for feature gating.

Best for: Users who want medication tracking alongside nutrition, movement, and symptom logs.

Limitations: The reviewed publisher materials do not describe an eight-zone status map comparable to OffGrid Dose's. Users who want no optional account or product analytics should review the policy before choosing it.

4. Glapp — Cross-Platform Account Sync

Glapp's current publisher materials advertise a native app and account sync across iPhone, Android, and Web. The listings document injection and smart site-rotation tracking, weight trends, side effects, medication-level estimates, progress reports, and reminders.

Glapp is a free download with in-app purchases. Check the current storefront to see which features require a purchase.

Best for: Users who want iPhone, Android, and Web access with account-based sync and the publisher-documented tracking suite.

Limitations: Account-based sync has a different data model from OffGrid Dose. Review Glapp's current privacy policy and storefront purchase screen before choosing it.

5. GLPeak — Best for AI-Powered Insights

GLPeak's current listing advertises an AI companion alongside injection logging, reminders, weight tracking, progress photos, and account-based cloud sync. The official materials reviewed do not document specific injection-rotation predictions, weight-trajectory predictions, or clinical validation for AI responses.

Best for: Users who want AI-driven analysis of their GLP-1 journey and are comfortable with the data processing that requires.

Limitations: In-app purchases and account-based cloud services are advertised. Review the current privacy policy and storefront before deciding; the public materials do not document every AI output or validation method.

6. MeAgain — Best for an All-in-One GLP-1 Routine

MeAgain is a GLP-1-specific tracker that combines shot and site logging with weight, protein, water, movement, and progress tools.

MeAgain is a free download with in-app purchases; check storefront details because its listing says some features require a subscription. It may suit users who want multiple parts of their GLP-1 routine in one app.

Best for: Users who want an all-in-one GLP-1 routine covering shots, nutrition goals, hydration, movement, and progress.

Limitations: Users should compare the depth of its injection-site and analytics tools with more narrowly focused trackers and review its current privacy policy before entering health data.

How to Choose the Best GLP-1 Tracker App

Selecting the right GLP-1 tracker depends on what you value most. Here are the key decision criteria:

Privacy Priority

If privacy is your primary concern, compare each app's current account, storage, backup, and analytics disclosures. OffGrid Dose requires no app account, keeps working health data on-device, and does not operate a company health database or upload health-record content to measurement services. Other apps use different combinations of private platform cloud storage, optional or required accounts, company cloud sync, and analytics.

Platform Requirements

Among the apps compared here, Shotsy, Pep, and Glapp publish Android availability. Glapp also documents iPhone, Android, and Web access. OffGrid Dose, GLPeak, and MeAgain publish iOS availability.

Injection Site Tracking

For users who want zone-level injection history, OffGrid Dose documents an eight-zone visual body map with color-coded status. The competitor materials reviewed did not document an equivalent eight-zone workflow; compare current screenshots if this dimension is decisive for you.

Budget

Glapp, Shotsy, and Pep are free downloads with in-app purchases. OffGrid Dose offers a the annual plan. Check each current storefront because purchase availability, feature gating, and pricing can vary by platform and region.

Nutrition and Lifestyle Tracking

If you want calories, protein, and water data through Apple Health on iOS, Shotsy documents that integration. OffGrid Dose intentionally focuses on injection and weight tracking without dietary features.

Data and Analytics Depth

OffGrid Dose documents dose-change markers, side-effect overlays, and progress-photo comparison. Shotsy advertises medication-level estimation, while GLPeak advertises an AI companion. The GLPeak materials reviewed do not document every AI output or validation method.

Frequently Asked Questions

What is the best GLP-1 tracker app in 2026?

The right GLP-1 tracker depends on your priorities. OffGrid Dose documents no app account, an eight-zone injection workflow, and on-device working storage. Shotsy documents iOS and Android availability plus Apple Health nutrition integration on iOS. Glapp documents iPhone, Android, and Web access and currently lists a free download with in-app purchases. Compare those documented differences rather than relying on a single market-wide ranking.

Do I need a dedicated app to track GLP-1 injections?

While you can track injections with a simple notes app or calendar, dedicated apps can organize site rotation, weight trends, dose changes, side effects, and reminders. Rotation tools may help reduce repeated same-site use, but they do not guarantee prevention of tissue changes.

Are GLP-1 tracker apps safe for my privacy?

This varies dramatically between apps. Many GLP-1 trackers use accounts or cloud services, which can put sensitive health data on external servers. OffGrid Dose is the notable exception — it does not receive user-health data or operate company cloud sync. Depending on Apple and device settings, an encrypted device backup may include app data. When evaluating any health app, check whether it requires an account, where data is stored, and whether it uses third-party analytics.

Can I track Mounjaro and Zepbound with these apps?

Yes. All six apps reviewed here support tirzepatide-based medications including Mounjaro and Zepbound, in addition to semaglutide-based medications like Ozempic and Wegovy. The mounjaro tracker app functionality is standard across the GLP-1 tracking category.

Is a free GLP-1 tracker good enough?

Glapp, Shotsy, and Pep are free downloads with in-app purchases. Their publisher listings document broader feature sets than reminder-only tools, and feature gating can change. Compare the live purchase screens and documented workflows before deciding.
