Finding the best GLP-1 tracker app can make the difference between guessing your way through treatment and actually seeing results. Whether you’re on Ozempic, Wegovy, Mounjaro, or Zepbound, the right app keeps your shots, side effects, nutrition, and progress in one place — so you stay consistent and get more out of every dose. In this guide, we compare the best GLP-1 tracking apps of 2026 and explain exactly what to look for.
What Makes the Best GLP-1 Tracker App?
Not every health app is built for GLP-1 medications. A general calorie counter or a basic pill reminder misses the things that actually matter on these drugs. The best GLP-1 tracker app should handle all of the following:
- Injection and dose logging with reminders and shot-site rotation
- Side effect tracking for nausea, fatigue, and digestion
- Nutrition built for GLP-1s — protein, fiber, water, and calories
- Weight, measurements, and progress photos in one timeline
- Support for every GLP-1 (semaglutide and tirzepatide, brand or compounded)
- iOS and Android availability, ideally free to start
With those criteria in mind, here are the top options.
The Best GLP-1 Tracker Apps in 2026
1. Pep — Best Overall GLP-1 Tracker App
Pep is our pick for the best GLP-1 tracker app because it’s purpose-built for exactly this journey. It logs each injection, reminds you when your next shot is due, and helps you rotate Ozempic injection sites so you avoid lumps and irritation. Beyond shots, Pep tracks weight, measurements, progress photos, side effects, and the nutrients that matter most on GLP-1s — protein, fiber, and water.
It works for every GLP-1 (Ozempic, Wegovy, Mounjaro, Zepbound, and compounded versions), runs on both iPhone and Android, and is free to download. You can explore the full feature set on the Pep GLP-1 tracker app page.
2. Shotsy — Simple Shot Logging
Shotsy focuses mainly on logging injections and reminders. It’s clean and easy, but it’s lighter on nutrition, side-effect tracking, and progress tools. If you want a fuller picture of your journey, see our detailed Pep vs Shotsy comparison.
3. MyFitnessPal — Nutrition-First
MyFitnessPal is excellent for calorie and macro counting, but it isn’t designed around GLP-1 medication or shot tracking. Many users pair it with a dedicated tracker. Our Pep vs MyFitnessPal breakdown covers the trade-offs.
4. Lose It! — Calorie Counting
Like MyFitnessPal, Lose It! is a solid calorie tracker but doesn’t handle medication, injection rotation, or GLP-1-specific side effects. See the Pep vs Lose It! comparison for details.
5. Generic Medication Reminder Apps
Basic reminder apps can ping you to take a dose, but they don’t track weight, side effects, nutrition, or rotation — so you lose the bigger picture that drives results.
Best GLP-1 Tracker App for Android
Plenty of trackers are iPhone-only, which leaves Android users stuck. Pep is fully available on Google Play, with the same injection logging, reminders, nutrition tracking, and progress tools as the iOS version. So if you’re searching for the best GLP-1 tracker app for Android, Pep delivers the complete experience on both platforms.
Is There a Tirzepatide-Specific App?
Yes. If you’re on Mounjaro or Zepbound (both tirzepatide), Pep works as a dedicated tirzepatide tracker app — tracking your weekly dose, titration schedule, side effects, and weight loss in one place. You don’t need a separate app for each medication; Pep adapts to whichever GLP-1 you’re taking.
How to Choose the Right One
Start with how you’ll actually use it. If you only want injection reminders, a simple logger may be enough. But if you want to connect the dots — doses, side effects, nutrition, and weight loss — choose an all-in-one tool. Consistency is what makes GLP-1s work, and the best GLP-1 tracker app is the one you’ll open every day. On Ozempic specifically? See our dedicated comparison of the best Ozempic tracker apps.
