OffGrid Dose vs Shotsy: Which GLP-1 Tracker Is Best for Privacy?
If you are comparing GLP-1 tracker apps, OffGrid Dose and Shotsy are two of the most talked-about options in 2026. Both help you track injections, monitor weight loss, and manage your semaglutide or tirzepatide journey — but they take fundamentally different approaches to your data.
The quick verdict: OffGrid Dose is the best GLP-1 tracker app for privacy. It stores everything on your device with zero accounts, zero cloud uploads, and zero data collection. Shotsy is the better choice if you need Android support, nutrition tracking through Apple Health, or oral GLP-1 tracking for medications like the Wegovy pill. Your priority — privacy or cross-platform features — should guide your decision.

Privacy and Data Handling
OffGrid Dose and Shotsy handle your health data in completely different ways. This is the single biggest difference between the two apps, and for many users it is the deciding factor.
### OffGrid Dose: On-Device Storage Only
OffGrid Dose was built from the ground up as a private GLP-1 tracker. There are no accounts, no sign-up screens, no email addresses collected, and no cloud servers involved. Every piece of data — your injection history, weight entries, progress photos, side effect logs — is stored locally on your iPhone using Apple's SwiftData framework.
There are no analytics SDKs embedded in the app. No Firebase. No third-party tracking code. The app works fully offline because it never needs to communicate with an external server. Your data physically cannot leave your device because there is nowhere for it to go.
This architecture means that if OffGrid Dose the company were breached tomorrow, there would be nothing to steal. Your GLP-1 health data simply does not exist on any server.
### Shotsy: Cloud-Based with iCloud and Firebase
Shotsy uses iCloud sync and Firebase for data storage. This enables useful features like cross-device syncing and Android support, but it means your injection records, weight data, and medication details are transmitted to and stored on external servers.
Shotsy states that data is encrypted "in transit and at rest," which is standard practice for cloud-based apps. They also list analytics partners in their privacy disclosures. While encryption provides a layer of protection, the fundamental reality is that your health data exists on servers you do not control.
For users who prioritize convenience and multi-device access, this tradeoff may be acceptable. For users who want a private GLP-1 tracker where no one else can access their medication data, it is not.
Injection Site Tracking
Proper injection site rotation is critical for GLP-1 medication effectiveness. Repeated injections in the same spot can cause lipohypertrophy, which reduces drug absorption and can lead to unpredictable dosing.
### OffGrid Dose: Visual Body Map with 8 Zones
OffGrid Dose features a visual body map that divides your injection areas into 8 distinct color-coded zones. Each zone is displayed with a clear status indicator:
- Green — Ready for injection. This zone has had enough rest time.
- Amber — Recently used. You can inject here if needed, but other zones are better.
- Red — Avoid. This zone was used too recently.
This injection site rotation app makes it nearly impossible to accidentally overuse a zone. You can see your entire rotation history at a glance, and the app recommends your next optimal site automatically. For people managing weekly injections over months or years, this level of tracking prevents the tissue damage that basic reminders cannot catch.
### Shotsy: Basic Area Suggestions
Shotsy offers injection site tracking, but it takes a more general approach. The app suggests broad areas (abdomen, thigh, upper arm) rather than tracking individual points within those areas. This is helpful for beginners who need to learn the approved sites, but it does not provide the granular rotation tracking that long-term GLP-1 users need.
If you are in the early months of your GLP-1 journey, Shotsy's approach may feel sufficient. As you accumulate dozens or hundreds of injections over time, the detailed zone tracking in OffGrid Dose becomes significantly more valuable.
Weight and Progress Tracking
Both apps offer weight tracking, but they approach the analytics differently.
### OffGrid Dose: Dose-Change Markers and Progress Photos
OffGrid Dose overlays dose-change markers directly on your weight chart. When you titrate from 0.25mg to 0.5mg, or from 0.5mg to 1.0mg, that change appears as a clear marker on your weight trend line. This lets you see exactly how each dose adjustment affects your weight loss trajectory — an invaluable insight during the titration process.
Side effect correlation is another distinctive feature. Your reported side effects are plotted alongside your weight data, so you can identify patterns. Did nausea spike after your last dose increase? Did it correlate with faster weight loss? These connections become visible.
Progress photos in OffGrid Dose are stored entirely on your device with a comparison slider for side-by-side viewing. Your body photos are never uploaded anywhere. For a private weight loss tracker app, this is essential — progress photos are among the most sensitive health data you can generate.
### Shotsy: Medication Level Estimation
Shotsy's premium tier includes medication level estimation charts that project how much semaglutide or tirzepatide is active in your system throughout the week. This is a unique and genuinely useful feature for understanding the pharmacokinetics of your medication.
Shotsy also integrates with Apple Health to pull in nutrition data — calories consumed, protein intake, and water intake. For users who want a comprehensive view of their GLP-1 journey alongside dietary habits, this integration adds real value.
Pricing Comparison
OffGrid Dose costs $4.99 per week with a 3-day free trial, or $29.99 per year. The annual plan works out to about $2.50 per month, making it one of the most affordable GLP-1 tracker apps available.
Shotsy offers free core features with a premium tier at approximately $49.99 per year. The free tier covers basic injection tracking and reminders. Features like medication level estimation and advanced analytics require the paid subscription.
If you only need basic tracking, Shotsy's free tier is hard to beat on price. If you want the full feature set from either app, OffGrid Dose's annual plan is roughly 40% less expensive than Shotsy's premium.
What Shotsy Does Better
