OffGrid Dose vs Pep: Which GLP-1 Tracker Is Right for You?
OffGrid Dose and Pep represent two very different philosophies in GLP-1 tracking. OffGrid Dose is a privacy-first GLP-1 tracker that stores everything on your device with no accounts and no cloud. Pep is a community-focused tracker that combines medication logging with social support features.
The quick verdict: OffGrid Dose is the better GLP-1 tracker if you want detailed injection site tracking, on-device progress photos, and complete privacy. Pep is the better choice if you value community support, want to connect with other people on GLP-1 medications, or need Android support. If privacy matters more than social features, choose OffGrid Dose. If shared accountability keeps you motivated, Pep is worth considering.

Privacy and Data Handling
This is the fundamental difference between these two apps.
OffGrid Dose stores every piece of data — injection records, weight, progress photos, side effects — locally on your iPhone using Apple's SwiftData framework. There are no accounts, no servers, no Firebase, and no analytics SDKs. Your data physically cannot leave your device because there is nowhere for it to go.
Pep requires an account and stores data in the cloud. This is a necessary tradeoff for enabling community features — you cannot share experiences with other users without some form of cloud infrastructure. Pep does offer anonymous sharing options, but the underlying data still resides on external servers.
For users who consider their GLP-1 medication data to be sensitive health information that should not exist on any server, OffGrid Dose is the only option. For users who accept cloud storage as a reasonable tradeoff for community engagement, Pep's approach is standard for the category.
Injection Site Tracking
OffGrid Dose features a visual body map with 8 distinct color-coded zones. Each zone displays whether it is ready (green), recently used (amber), or should be avoided (red). The app recommends your next optimal injection site automatically and maintains a complete rotation history. This level of tracking directly prevents lipohypertrophy from repeated same-site injections.
Pep offers basic injection tracking that logs when and where you inject at a general level. It covers the fundamentals but does not provide the zone-level granularity or visual rotation guidance that OffGrid Dose delivers.
If you are managing weekly injections over months or years, the difference in site tracking depth becomes significant. Long-term GLP-1 users benefit from the detailed rotation system in OffGrid Dose.
Community and Social Features
This is where Pep has a clear advantage. Pep is built around the idea that medication journeys are easier with support. The app includes community features where users can share experiences, ask questions, and provide encouragement — anonymously if desired.
OffGrid Dose has no community features by design. The app's privacy architecture means there are no accounts, no user profiles, and no way to communicate with other users. If you want social support for your GLP-1 journey, you will need to find it outside the app.
For some users, the accountability and motivation from a community are essential. For others, privacy is non-negotiable. This is a genuine tradeoff with no wrong answer — it depends entirely on what helps you stay consistent.
Weight and Progress Tracking
OffGrid Dose overlays dose-change markers on your weight chart so you can see exactly how each titration step affects your weight loss trajectory. Side effects are correlated on the same chart for pattern identification. Progress photos are stored on-device with a comparison slider and never leave your phone.
Pep provides standard weight charts and logging. The charting is functional and covers the basics of tracking your weight over time, but it does not include the dose-correlation or side-effect overlay features that OffGrid Dose provides.
Pricing Comparison
Pep offers a free tier with basic tracking features, with premium unlocking additional analytics and community features. OffGrid Dose costs $4.99 per week with a 3-day free trial, or $29.99 per year (approximately $2.50 per month).
If cost is your primary concern and you need only basic tracking, Pep's free tier is the more accessible starting point. For the full feature set, OffGrid Dose's annual plan at $29.99/year represents strong value.

Frequently Asked Questions
### Is OffGrid Dose better than Pep?
OffGrid Dose is better for privacy, injection site tracking, and weight analytics with dose correlation. Pep is better for community support, Android access, and free basic tracking. The right choice depends on whether you value privacy or social support more.
### Does Pep track injection sites like OffGrid Dose?
Pep offers basic injection tracking but does not include the 8-zone visual body map with color-coded rotation guidance that OffGrid Dose provides. For long-term GLP-1 users concerned about injection site rotation, OffGrid Dose's tracking is significantly more detailed.
### Can I use Pep without an account?
No. Pep requires an account for its core functionality, including community features. OffGrid Dose is the GLP-1 tracker that requires no account, no email, and no personal information.
### Which app is better for someone just starting GLP-1 medications?
Both are reasonable starting points, but they serve different needs. If you want to connect with others on a similar journey, Pep's community features can help. If you want to focus on tracking your data privately and building a detailed injection rotation history from day one, OffGrid Dose is the better foundation.
