Best GLP-1 Tracker Apps in 2026 — Ozempic, Wegovy & Mounjaro

Why a GLP-1 Tracker Matters More Than a Phone Alarm

GLP-1 medications aren't a set-it-and-forget-it situation. You're titrating doses over weeks, tracking side effects that shift at each dosage level, rotating injection sites, and monitoring weight loss alongside symptoms like nausea, sulfur burps, and appetite changes.

A weekly phone alarm reminds you to inject. It doesn't tell you which side you pinned last week, whether your nausea got worse when you jumped from 0.5mg to 1mg, or how your weight trend correlates with your current dose.

That's what a real tracker handles. The best ones log your doses, map your injection sites, chart your side effects over time, and show you how your body responds as you titrate up.

The 7 Best GLP-1 Tracker Apps in 2026

We downloaded, tested, and compared every GLP-1 tracking app we could find. Here's what each one actually does well, where it falls short, and who it's for.

1. Regimen

If you're tracking one GLP-1, Regimen is completely free with every feature unlocked. No paywalls. You get the half-life visualizer, correlation charts, injection site tracking with rotation suggestions, Apple Health and Health Connect integration, and the in-app reconstitution calculator for compounded semaglutide.

If your protocol grows later (adding BPC-157 for gut side effects, GHK-Cu for loose skin, TRT, or other compounds), Regimen handles that too with a library of 600+ compounds on the paid tier. At $4.99/mo, it's half the monthly cost of Shotsy.

What it does best: Full-featured GLP-1 tracking at zero cost for a single compound. Correlation charts that show how dose changes affect your weight, sleep, and energy over time.

Where it falls short: Newer app with a smaller review base (70+ reviews vs. Shotsy's 20,000). No built-in food or macro logging.

Best for: Anyone who wants a full-featured tracker without paying for it. Also the pick if your protocol includes supporting compounds alongside your GLP-1.

2. Shotsy

Shotsy is the market leader, and those numbers aren't accidental. Nearly 20,000 reviews at a 4.85 rating means this app works for the majority of GLP-1 users.

The standout feature is medication level charts. Shotsy estimates how much semaglutide or tirzepatide is in your system between doses, giving you a visual curve that helps explain why side effects hit harder on certain days.

What it does best: Dominant GLP-1 tracker with medication level visualization. Massive community validation. Polished experience.

Where it falls short: Pricing has increased since the company took outside investment. Several reviews mention features that used to be free are now behind the paywall. At $9.99/mo, it's the most expensive monthly option. If you add peptides or TRT alongside your GLP-1, Shotsy can't track those.

Best for: People taking a single GLP-1 medication who want the most established, feature-rich tracker and don't mind the price.

3. Glapp

Glapp is the most interesting niche tool on this list. It's a free web app built around GLP-1 pharmacokinetic cycle visualization. The PK visualization shows your estimated medication levels over time based on your dose and injection timing.

The standout feature: Glapp shows how your personal results compare against published clinical studies. You can see whether your weight loss, side effects, or response timeline lines up with what the trials showed. It also tracks "food noise," the GLP-1 community's term for intrusive food thoughts.

What it does best: Free pharmacokinetic visualization. Clinical study comparison. "Food noise" tracking.

Where it falls short: Web-only means no native push notifications, no Apple Health integration, and no offline access.

Best for: Data-oriented GLP-1 users who want to visualize their medication levels and track food noise as a supplement to a native tracker app.

4. MeAgain

MeAgain positions itself as an "all-in-one GLP-1 app" with shot logging, reminders, progress tracking, protein tracking, and water intake logging.

What it does best: Simple GLP-1 tracking with protein and water logging for users who want the basics without feature overload.

Where it falls short: The 3.8-star rating is the lowest of any native app on this list. 19 reviews doesn't give you much signal on reliability.

Best for: Hard to recommend with current ratings. If the app improves, the focused approach could work for GLP-1-only users who want simplicity.

5. GLP1 Tracker (Tirzepatide)

This app does exactly what the name says: injection logging for GLP-1 medications, with a focus on tirzepatide (Mounjaro/Zepbound). It covers injection logging, side effect tracking, and charts for weight, calories, protein, and water.

What it does best: GLP-1 specific tracking with a decent feature set. Clean, focused experience.

Where it falls short: iOS only. With 61 reviews versus Shotsy's 20,000, the community validation gap is significant.

Best for: iOS users who want a GLP-1 tracker and prefer a smaller, independent app over Shotsy.

6. DoseDiary

DoseDiary is a lightweight PWA that handles simple dose scheduling and progress tracking. Nothing to install. The public development roadmap is a nice transparency touch.

What it does best: Zero friction to start. Nothing to download or install. Transparent development.

Where it falls short: Web-only carries the same limitations as Glapp: no native notifications, no health app integrations.

Best for: Users who want to try dose logging without committing to an app download.

7. GlucoPal / Zepbound Tracker

This developer publishes separate app listings targeting specific medications. The apps offer dose logging, progress tracking, and medication-specific features.

What it does best: Medication-specific store listings make them easy to find.

Where it falls short: Multiple app names for what appears to be a similar product creates confusion.

Best for: Users searching for a tracker specific to their exact medication. Download and test before committing.

How to Pick the Right App

What GLP-1 Users Actually Need From a Tracker — Insights From Regimen Data

GLP-1 receptor agonists are the most tracked compound category on Regimen, and the data around how these users behave reveals needs that go well beyond a weekly dose reminder. Nearly 70% of Regimen subscribers list weight loss or body composition improvement as a primary goal — and the most common frustration they report is not forgetting doses. It is not knowing whether their protocol is actually working the way they want it to. Weight on a scale fluctuates wildly on GLP-1 medications, and users need a clearer picture than a single number can provide.

That is why body composition tracking matters as much as dose tracking for GLP-1 users. Across Regimen, weight and body fat are among the most actively logged health metrics — and a growing share of users are going beyond the scale to track body fat percentage, sleep quality, and blood pressure alongside their GLP-1 protocol. For anyone on a GLP-1, the difference between losing fat and losing fat-plus-muscle is the difference between a successful protocol and a concerning one. A tracker that captures both dosing and health metrics in one place gives you the full picture your scale cannot.

Regimen was built for this — GLP-1 dose tracking with titration support, integrated weight and body composition logging, and a clear view of how your health metrics trend over time. Whether you are on a GLP-1 alone or combining it with other treatments your provider has prescribed, everything lives in one app.
