Best Zepbound Tracker App in 2026: Tirzepatide Tracking Made Simple
Zepbound (tirzepatide) by Eli Lilly has become one of the most effective weight management medications available. As a dual GIP/GLP-1 receptor agonist, it delivered up to 22.5% average weight loss in clinical trials — numbers that have made it one of the most prescribed weight loss medications in the country. But with a complex titration schedule, weekly injections, and the need to track weight alongside dose changes, most Zepbound users need a reliable tracker app.
This guide covers what to look for in a Zepbound tracker app, compares the top options available in 2026, and explains why OffGrid Dose was built specifically for this use case.
Understanding Zepbound: What You Need to Track
Zepbound is the weight management brand of tirzepatide — the same molecule found in Mounjaro (which is approved for type 2 diabetes). Both brands share the same dose schedule and injection protocol, but Zepbound is specifically indicated and marketed for chronic weight management in adults with obesity or overweight with at least one weight-related comorbidity.
### Zepbound Dose Titration Schedule
Zepbound follows a structured titration schedule to minimize side effects. Each dose level is maintained for at least 4 weeks before increasing:
| Dose Level | Weekly Dose | Duration | Purpose |
|-----------|-------------|----------|---------|
| Starting dose | 2.5 mg | 4 weeks | Acclimation — sub-therapeutic |
| Dose 2 | 5 mg | 4 weeks | First therapeutic dose |
| Dose 3 | 7.5 mg | 4 weeks | Intermediate dose |
| Dose 4 | 10 mg | 4 weeks | Standard maintenance |
| Dose 5 | 12.5 mg | 4 weeks | Higher maintenance |
| Maximum dose | 15 mg | Ongoing | Maximum approved dose |
Not everyone will titrate to 15mg. Your prescriber will determine the right maintenance dose based on your response, tolerability, and weight loss goals. Some people achieve excellent results at 10mg and stay there.
A good tracker app should understand this schedule and make it easy to log dose changes as they happen.
### What Zepbound Users Need to Track
1. Weekly injection date and time — Zepbound is injected once weekly on the same day each week.
2. Current dose — Which of the six dose levels you are on.
3. Injection site — Abdomen, thigh, or upper arm, with proper rotation.
4. Weight — Weekly or periodic weigh-ins to monitor progress.
5. Side effects — Especially during dose titration when gastrointestinal symptoms are most common.
6. Dose-change dates — When you moved from one dose level to the next.

Injection tracking: None.
Weight analytics: Basic weight chart without medication context.
Side effects: None.
Best for: General diet tracking to complement a dedicated GLP-1 tracker, not as a standalone Zepbound tracker.
### Generic Medication Reminder Apps
Apps like Medisafe or Round Health are designed for medication reminders, not for tracking the specific data points that GLP-1 users need. They will remind you to take your shot, but they do not track injection sites, correlate side effects with dose changes, or build weight analytics with dose markers.
Best for: Setting injection reminders as a supplement to a dedicated tracker — not as a primary Zepbound tracking solution.
Why Privacy Matters for Zepbound Tracking
Weight loss medication data is sensitive health information. Here is what you should consider when choosing a tracker:
What data is being collected? Many health apps collect not just the data you enter, but also device information, usage patterns, and sometimes location data. Read the privacy policy.
Where is data stored? Cloud-based apps send your health data to external servers. Even if encrypted, that data exists outside your control. If the company is acquired, shuts down, or experiences a breach, your health data is at risk.
Who can access it? Some apps share data with third parties for analytics, advertising, or "research." Your Zepbound dose history, weight, and side effects are nobody else's business unless you choose to share them.
What happens if you stop paying? With cloud-based apps, your data may become inaccessible if you cancel your subscription or the service shuts down.
OffGrid Dose takes a fundamentally different approach: your data never leaves your iPhone. There are no accounts to create, no servers to sync to, and no cloud to trust. Your Zepbound tracking data is stored locally using Apple's SwiftData framework, meaning it is protected by your device's encryption and biometric security.
OffGrid Dose Features for Zepbound Users
### Pre-loaded Tirzepatide Doses
When you select Zepbound (or Mounjaro) as your medication, OffGrid Dose pre-loads the complete tirzepatide dose schedule: 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg, and 15mg. Logging a dose change is a single tap — select your new dose level and the app automatically places a marker on your chart.
For compounded tirzepatide users, the app also supports custom dose entry, so you can log any dose prescribed by your provider.
### Visual Body Map for Injection Sites
Zepbound is injected subcutaneously in the abdomen, thigh, or upper arm. OffGrid Dose displays a visual body map divided into 8 zones across these three areas. Each zone is color-coded:
- Green — This zone has been rested long enough and is ready for your next injection.
- Amber — This zone was used recently. It is best to choose a green zone instead.
- Red — This zone was used too recently. Avoid it to prevent tissue damage.
The app recommends your next injection site automatically based on your rotation history. You never have to remember where you last injected — the body map shows you at a glance.
### Weight Analytics with Dose Context
Your weight chart in OffGrid Dose is not just a line graph. It includes:
- Dose-change markers at each titration step
- A smoothed trend line that filters daily fluctuations
- Rate of loss calculated per dose level
- A projected goal date based on your current trajectory
- Optional side effect overlay
This means you can see exactly how moving from Zepbound 5mg to 7.5mg affected your weight loss rate — information that is invaluable for conversations with your prescriber.
### 15-Second Daily Check-In
OffGrid Dose is designed to be fast. The daily check-in takes about 15 seconds: log your weight (if it is a weigh-in day), note any side effects, and you are done. On injection day, you also log your injection and select the site on the body map. Speed matters for consistency — the faster the check-in, the more likely you are to do it every day.
### Progress Photos with Comparison Slider
Visual progress can be just as motivating as the numbers on the scale. OffGrid Dose lets you take progress photos that are stored entirely on your device. The comparison slider lets you view before and after photos side by side. No cloud upload, no server storage — these photos exist only on your iPhone.
Zepbound Injection Sites: A Quick Guide
For Zepbound users who are new to self-injection, here is a quick reference for approved injection sites:
### Abdomen
The most commonly used site. Inject into the fatty tissue at least 2 inches away from your navel. Avoid areas with scars, bruises, or stretch marks. The abdomen generally provides the most consistent absorption.
### Front of Thigh
Inject into the middle third of the front of your thigh. Avoid the inner thigh and areas close to the knee or hip. The thigh is a convenient site for self-injection.
### Back of Upper Arm
The fatty area on the back of the upper arm. This site may require assistance from another person since it is difficult to reach and inject properly on your own.
### Rotation Protocol
Never inject in the same exact spot twice in a row. Even within the same body area (for example, the abdomen), move to a different zone. OffGrid Dose automates this by tracking your injection history and recommending the optimal next zone.
Frequently Asked Questions
### Is Zepbound the same as Mounjaro?
Zepbound and Mounjaro contain the same active ingredient — tirzepatide — made by Eli Lilly. The difference is the indication: Mounjaro is approved for type 2 diabetes, while Zepbound is approved for chronic weight management. The dose schedule (2.5mg through 15mg) is identical. OffGrid Dose supports both medications with the same tirzepatide dose presets.
### What makes OffGrid Dose different from other Zepbound tracker apps?
Three things: privacy (100% on-device, no accounts or cloud), the visual body map for injection site rotation (8 color-coded zones with automatic recommendations), and dose-correlated analytics (weight chart with dose-change markers, rate of loss per dose level, and goal projections). Most other apps either lack medication-specific features or require cloud-based accounts.
### Can I track compounded tirzepatide with OffGrid Dose?
Yes. While OffGrid Dose pre-loads the standard tirzepatide doses (2.5mg through 15mg), it also supports custom dose entry. If your compounding pharmacy provides a different concentration or your prescriber specifies a non-standard dose, you can enter it manually.
### How much weight can I expect to lose on Zepbound?
Clinical trials (SURMOUNT-1) showed average weight loss of 15% at the 5mg dose, 19.5% at the 10mg dose, and 22.5% at the 15mg dose over 72 weeks. Individual results vary significantly based on starting weight, diet, activity level, and other factors. OffGrid Dose tracks your personal trajectory and projects a goal date based on your actual rate of loss.
### Does OffGrid Dose send injection reminders?
OffGrid Dose focuses on tracking and analytics rather than reminders. You can set your preferred injection day when configuring your medication, and the app will prompt you during your daily check-in on injection day. For more robust reminders, you can use your iPhone's built-in Reminders app or a dedicated medication reminder app alongside OffGrid Dose.
### Is my weight data shared with anyone?
No. OffGrid Dose has no servers, no accounts, and no cloud sync. All data — weight, injections, side effects, progress photos — is stored locally on your iPhone using SwiftData. Your data is protected by your device's passcode and biometric security (Face ID or Touch ID). Nobody can access your data unless they have physical access to your unlocked device.
### Can I use OffGrid Dose on Android?
OffGrid Dose is currently available on iOS only. It is built natively for iPhone using SwiftUI and SwiftData. There is no Android version at this time.
