OffGrid Dose vs Glapp: Privacy Tracker vs Free GLP-1 App
OffGrid Dose and Glapp sit at opposite ends of the GLP-1 tracker spectrum. OffGrid Dose is a privacy-first paid tracker with advanced injection site rotation and on-device storage. Glapp is a completely free tracker with a web companion that covers the basics of injection logging and weight tracking.
The quick verdict: OffGrid Dose is the better GLP-1 tracker for serious, long-term medication management. Its visual body map, dose-change weight markers, progress photos, and complete privacy make it the stronger tool. Glapp is the better choice if you are on a tight budget and need basic tracking to get started — it costs nothing and includes web access. If you can afford $29.99/year, OffGrid Dose delivers substantially more value.

| Injection Site Tracking | Visual body map, 8 color-coded zones | Basic logging |
| Weight Charts | Dose-change markers, side effect correlation | Basic charts |
| Progress Photos | On-device with comparison slider | Not available |
| Side Effect Tracking | Correlated on weight chart | Limited |
| Web Access | No | Yes (web companion) |
| Platform | iOS | iOS + Web |

Privacy and Data Handling
OffGrid Dose stores all data locally on your iPhone using Apple's SwiftData framework. There are no accounts, no cloud servers, no Firebase, and no analytics SDKs. Your injection records, weight entries, and progress photos never leave your device.
Glapp requires an account and uses cloud-based storage. This is partly what enables its web companion feature — to show your data in a browser, the data needs to exist on a server. For users who do not consider their GLP-1 data to be particularly sensitive, this tradeoff enables the convenience of web access. For users who want their medication history to exist only on their physical device, OffGrid Dose is the only option.
Feature Depth
The biggest difference beyond privacy is feature depth. OffGrid Dose is purpose-built for long-term GLP-1 medication management with features that compound in value over months and years of use:
The visual body map with 8 color-coded injection zones prevents lipohypertrophy from repeated same-site injections. Dose-change markers on weight charts show exactly how each titration step affects your trajectory. Side effects are overlaid on the same chart for pattern identification. Progress photos with a comparison slider let you track visual changes privately.
Glapp covers the fundamentals — injection logging, weight tracking, medication reminders — at a level that is functional for users in their first weeks on a GLP-1 medication. As your tracking history grows and the need for rotation analysis, dose correlation, and side effect patterns increases, Glapp's basic feature set becomes a limitation.
The Free vs Paid Question
The honest comparison here is whether the additional features in OffGrid Dose justify the cost over a free alternative.
At $29.99/year (roughly $2.50/month), OffGrid Dose provides the most detailed injection site rotation tracking available, dose-correlated weight analytics, on-device progress photos, and complete privacy. For context, this is less than the cost of a single copay for most GLP-1 medications.
Glapp costs nothing and covers basic tracking. For some users — especially those in their first month who are unsure about long-term medication use — starting with a free option makes sense.
The pragmatic approach: start with Glapp if you need to, but plan to switch to OffGrid Dose once your tracking needs mature. The earlier you start building a detailed injection rotation history, the more valuable it becomes over time.
What Glapp Does Better
- Price. Glapp is completely free. OffGrid Dose requires a subscription after the 3-day free trial.
- Web access. Glapp's web companion lets you view your GLP-1 data on a computer. OffGrid Dose is iPhone-only with no web interface.
- Entry barrier. Zero cost means zero commitment. Good for people just starting who are unsure about dedicated tracking.
What OffGrid Dose Does Better
- Privacy. No accounts, no cloud, no servers, no analytics SDKs. Everything stays on your device.
- Injection site rotation. Visual body map with 8 color-coded zones versus basic logging.
- Weight analytics. Dose-change markers and side effect correlation versus basic charts.
- Progress photos. On-device comparison slider. Glapp does not offer this.
- Offline functionality. Full feature set without internet. Glapp depends on connectivity for web sync.
- Feature depth. Every tracking feature is built for long-term GLP-1 medication management.
Frequently Asked Questions
### Is Glapp good enough for tracking GLP-1 injections?
Glapp covers the basics of injection logging and weight tracking at no cost. For users in their first few weeks on a GLP-1 medication who want simple tracking, it is adequate. For long-term medication management with proper injection site rotation, dose correlation, and side effect tracking, OffGrid Dose provides substantially more capability.
### Can I switch from Glapp to OffGrid Dose?
Yes. Since OffGrid Dose does not import data from other apps (your data starts fresh on your device), the best time to switch is as early as possible so you build your injection rotation history from the start.
### Why does OffGrid Dose cost money when Glapp is free?
OffGrid Dose charges for its subscription because it does not monetize user data in any way. There are no ads, no analytics, no data collection, and no cloud infrastructure costs passed through data monetization. The subscription directly funds development. Glapp's free model is supported by its cloud infrastructure and account system.
### Does Glapp have injection site rotation like OffGrid Dose?
No. Glapp offers basic injection logging but does not include the 8-zone visual body map with color-coded rotation guidance that OffGrid Dose provides. Detailed site rotation tracking is one of the primary reasons to upgrade from a free tracker.
Key Takeaways
- OffGrid Dose is the better long-term GLP-1 tracker with advanced injection site rotation, dose-correlated weight charts, and complete on-device privacy
- Glapp is the best free GLP-1 tracker for basic injection logging and weight tracking with web companion access
- OffGrid Dose at $29.99/year costs roughly $2.50/month — less than a typical GLP-1 medication copay
- The feature depth gap between these apps grows as your tracking history accumulates over months
- Both apps support major GLP-1 medications including Ozempic, Wegovy, Mounjaro, and Zepbound
