Detailed Reviews
### 1. OffGrid Dose — Best for Privacy and Injection Site Tracking
OffGrid Dose is the only major GLP-1 tracker that operates with zero cloud infrastructure. There are no accounts, no servers, no Firebase, and no analytics SDKs. Every piece of data — injection records, weight entries, progress photos, side effect logs — stays on your iPhone using Apple's SwiftData framework.
The app's standout feature is its visual body map with 8 color-coded injection zones. Each zone displays a clear status: green (ready), amber (recent), or red (avoid). This is the most detailed injection site rotation system available in any semaglutide tracker app, and it directly addresses the real medical concern of lipohypertrophy from repeated same-site injections.
Weight tracking includes dose-change markers that show exactly how each titration step (for example, moving from 0.25mg to 0.5mg of semaglutide) affects your weight trend. Side effects are overlaid on the same chart for correlation analysis. Progress photos are stored on-device with a before-and-after comparison slider — they never leave your phone.
The daily tracking flow takes approximately 15 seconds. There is no sign-up friction, no sync delays, and full offline functionality. Pricing is $4.99 per week with a 3-day free trial, or $29.99 per year.
Best for: Users who want a private GLP-1 tracker with no data collection, advanced injection site rotation, and on-device progress photos. The best ozempic tracker app that does not require an account.
Limitations: iOS only. No nutrition tracking. No oral GLP-1 support.
### 2. Shotsy — Best for Cross-Platform and Nutrition Tracking
Shotsy is the largest GLP-1 tracker app by user base, with approximately 286,000 active users and nearly 1 million downloads. It carries a 4.8-star rating and recently raised $2.25 million in venture capital funding.
The app's core features — injection reminders, basic site rotation, and weight logging — are free. The premium tier (~$49.99/year) adds medication level estimation charts that project active semaglutide or tirzepatide levels throughout the week. Shotsy also integrates with Apple Health to pull in nutritional data including calories, protein, and water intake.
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. Data is synced through iCloud and Firebase, with encryption in transit and at rest.
Best for: Users who want a mounjaro tracker app or wegovy tracker app with cross-platform support, nutrition tracking, and a large community. A strong shotsy alternative is hard to find for Android users.
Limitations: Requires an account. Uses cloud storage with Firebase and analytics partners. Injection site tracking is less granular than OffGrid Dose. Premium pricing is higher than competitors.
### 3. Pep — Best for Community Features
Pep positions itself as a social companion for the GLP-1 journey. Available on both iOS and Android, the app includes community features that let users share experiences, tips, and progress (anonymously if desired).
The core tracking features cover injection reminders, weight logging, and basic medication management. Pep offers both free and premium tiers, with premium unlocking additional analytics and community features.
Best for: Users who want social support and community engagement alongside their GLP-1 tracking. Works well as a supplement to a more feature-rich tracker.
Limitations: Cloud-based storage with account requirements. Injection site tracking is basic. Community features may not appeal to privacy-focused users.
### 4. Glapp — Best Free Option
Glapp offers a completely free GLP-1 tracking experience on iOS with a web companion app. The app covers the basics: injection logging, weight tracking, and medication reminders. The web interface is useful for users who want to view their data on a larger screen.
The free price point makes Glapp accessible to everyone, and it serves as a solid entry point for people just starting their GLP-1 medication who want simple tracking without committing to a paid subscription.
Best for: Budget-conscious users who need basic GLP-1 injection tracking and want web access. A reasonable starting point before graduating to a more full-featured app.
Limitations: Cloud-based with account required. Limited injection site tracking. Basic analytics compared to OffGrid Dose or Shotsy. Feature set is relatively thin.
### 5. GLPeak — Best for AI-Powered Insights
GLPeak takes an AI-first approach to GLP-1 tracking. The app uses artificial intelligence to analyze your medication data and provide personalized insights about your progress, potential side effect patterns, and optimization suggestions.
The AI features are GLPeak's differentiator. The app attempts to surface non-obvious patterns in your data that you might not notice on your own, such as correlations between injection timing and side effect severity, or predictions about weight loss trajectory based on your titration schedule.
Best for: Users who want AI-driven analysis of their GLP-1 journey and are comfortable with the data processing that requires.
Limitations: Premium subscription required. AI features require cloud data processing, which raises privacy questions. Newer app with a smaller user base.
### 6. MeAgain — Best for General Wellness
MeAgain takes a broader approach to health tracking that includes GLP-1 medication management as one component of a wider wellness platform. The app covers general health metrics alongside injection tracking.
The freemium model offers basic tracking for free with premium features behind a subscription. MeAgain appeals to users who want a single app for multiple health concerns rather than a specialized GLP-1 tracker.
Best for: Users who want GLP-1 tracking integrated into a broader wellness platform rather than a standalone medication tracker.
Limitations: GLP-1-specific features are less developed than dedicated trackers. Cloud-based with account required. Jack-of-all-trades approach may mean less depth in any single area.
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, the decision is straightforward. OffGrid Dose is the only major GLP-1 tracker that stores all data on-device with no accounts, no cloud servers, and no analytics SDKs. It is the best GLP-1 app for privacy by a significant margin. Every other app on this list requires an account and uses some form of cloud storage.
### Platform Requirements
If you use an Android phone, your options narrow to Shotsy and Pep. OffGrid Dose, GLPeak, and MeAgain are iOS only. Glapp offers a web companion but the primary app is iOS.
### Injection Site Tracking
For serious injection site rotation — the kind that prevents lipohypertrophy over months and years of GLP-1 use — OffGrid Dose's 8-zone visual body map is unmatched. No other app provides this level of granular, color-coded site tracking. If you are on a long-term semaglutide or tirzepatide regimen, this feature alone may justify your choice.
### Budget
Glapp is the best free GLP-1 tracker. Shotsy offers the most features in its free tier among the paid apps. For premium features, OffGrid Dose at $29.99/year is the most affordable annual plan. Shotsy's premium at ~$49.99/year is the most expensive.
### Nutrition and Lifestyle Tracking
If you want your GLP-1 tracker to also monitor calories, protein, and water intake, Shotsy is the clear winner with its Apple Health integration. OffGrid Dose intentionally focuses on injection and weight tracking without dietary features.
### Data and Analytics Depth
OffGrid Dose leads with dose-change markers, side effect correlation, and progress photo comparison. Shotsy offers medication level estimation. GLPeak provides AI-powered analysis. Your preference for data presentation style should guide this choice.
Frequently Asked Questions
### What is the best GLP-1 tracker app in 2026?
The best GLP-1 tracker app depends on your priorities. OffGrid Dose is the best for privacy and injection site tracking. Shotsy is the best for cross-platform support and nutrition integration. Glapp is the best free option. There is no single "best" app because users have different needs — privacy-focused users and feature-focused users will make different choices.
### Do I need a dedicated app to track GLP-1 injections?
While you can track injections with a simple notes app or calendar, a dedicated GLP-1 tracker provides significant advantages: automated injection site rotation to prevent tissue damage, weight trend analysis with dose correlation, side effect logging, and injection reminders. These features are difficult to replicate manually, especially over months of treatment.
### Are GLP-1 tracker apps safe for my privacy?
This varies dramatically between apps. Most GLP-1 trackers require accounts and use cloud storage, which means your sensitive health data exists on external servers. OffGrid Dose is the notable exception — it is an ozempic tracker app that does not collect any data because everything stays on your device. 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?
Free options like Glapp and Shotsy's free tier cover basic injection reminders and weight logging. For many users starting their GLP-1 journey, this is sufficient. However, as your treatment progresses, features like detailed injection site rotation, dose-change markers on weight charts, and progress photo tracking become more valuable. The best approach may be to start free and upgrade when you see the need.
