6 Best GLP-1 Tracker Apps for Semaglutide

The best GLP-1 tracker app handles the things general medication apps get wrong: weekly injection schedules, dose titration over months, injection site rotation, and a mix of oral and injectable meds in one place. A phone alarm doesn't cut it for semaglutide or tirzepatide. Below are six apps people actually use to track GLP-1 injections in 2026 — what each does well, where each falls short, and which one fits your weekly routine.

Quick Reference: Top 3 GLP-1 Tracker Picks

1. DoneDose -- Best for injection site rotation and managing GLP-1s alongside other medications. Visual body map tracks where you've injected and where to go next.
2. Shotsy -- Best for a clean, GLP-1-focused experience. Purpose-built for weekly injections with a minimal, intuitive interface.
3. Pep (GLP-1 Tracker) -- Best for users who want food logging and weight tracking alongside their GLP-1 injections in a single app.

Feature Comparison

Individual App Reviews

DoneDose

DoneDose was built for injectable medications first, and it shows. The headline feature for GLP-1 users is the visual body map for injection site rotation — you tap where you injected, and the app tracks site history with color-coded status showing which areas are resting and which are ready. This matters clinically because repeated injections in the same spot cause lipohypertrophy, which alters how your body absorbs the drug.

Where DoneDose really separates itself is multi-medication support. If you're on semaglutide plus daily metformin, or tirzepatide alongside oral medications, everything lives in one tracker with the right scheduling logic for each. Weekly injections and daily pills don't get jammed into the same template.

Honest weakness: DoneDose doesn't include food logging, weight charting, or AI-powered features. If tracking meals and weight trends alongside your GLP-1 is important to you, you'll need a separate app or a companion like Pep or Weightly for that side of things.

Shotsy

Shotsy is purpose-built for GLP-1 injections and keeps its scope intentionally narrow. The interface is clean and focused — set up your medication, get weekly reminders, log your injection. It handles dose titration tracking well, making it easy to see where you are in a step-up schedule. The design feels like it was made by someone who actually takes a weekly injection and wanted less clutter, not more.

Basic site rotation guidance is included, but it's not as detailed as DoneDose's body map approach. Shotsy suggests rotating between general areas rather than tracking individual injection points over time.

Honest weakness: Limited multi-medication support. If your regimen includes anything beyond a single GLP-1, Shotsy starts to feel constrained. It's best for people whose only injectable is semaglutide or tirzepatide and nothing else.

Pep (GLP-1 Tracker)

Pep positions itself as a companion app for people on GLP-1 medications, combining injection tracking with food logging, weight monitoring, and lifestyle coaching. If you're taking Wegovy or Zepbound primarily for weight management, Pep's approach of unifying the injection log with the diet log makes genuine sense — the medication and the nutrition are part of the same treatment.

The injection tracking itself is functional but not its strength. Reminders work, dose logging works, but site rotation tracking is limited. Where Pep shines is the broader context: seeing your weight trend alongside your injection history gives you a picture that a standalone injection tracker can't.

Honest weakness: The food logging and coaching features can feel heavy if all you want is a clean injection tracker. And the injection-specific features — site rotation, multi-medication support — are thinner than dedicated options.

GLPeak

GLPeak focuses on helping users track their GLP-1 titration journey. It's particularly good at visualizing where you are in your dose escalation — helpful during the first several months when you're stepping up from starter doses and watching for tolerability. The timeline view makes it easy to see when your last dose increase was and when the next one might be appropriate to discuss with your prescriber.

Reminders are reliable and the interface is straightforward. GLPeak also includes some symptom logging that lets you note side effects relative to dose changes, which is useful data to bring to appointments.

Honest weakness: No injection site rotation tracking at all. If you're past the titration phase and settled into a maintenance dose, GLPeak's core value proposition diminishes — it's strongest during the ramp-up period.

Glapp

Glapp takes a community-oriented approach to GLP-1 tracking, combining basic injection logging with social features where users can share their experiences. The tracking fundamentals are present — you can log injections, set reminders, and see your history. The social component can be genuinely motivating for some users who benefit from peer accountability.

The app is free, which lowers the barrier to trying it. The interface is clean enough and setup is minimal.

Honest weakness: The social features can be a double-edged sword — medical misinformation in community spaces is a real concern. The actual tracking features are basic. No site rotation, no multi-medication support, no dose calculator. If you need robust tracking, Glapp is more of a community with a tracker attached than a tracker with a community.

Weightly

Weightly approaches GLP-1 tracking from the weight management angle, combining injection logging with weight tracking, body measurements, and progress photos. The weight trend visualization is well done — it smooths out daily fluctuations and shows you the actual trajectory, which is more useful than watching the scale bounce day to day.

Injection reminders and logging are competent, and the app handles weekly scheduling properly. Seeing your weight response correlated with your injection timeline can be genuinely informative.

Honest weakness: Like Pep, the injection-specific features are secondary to the weight tracking. No site rotation. Limited support for multiple injectable medications. If you're taking a GLP-1 for diabetes management rather than weight loss, the weight-centric framing may not fit.

How We Evaluated

We assessed each app against the criteria that matter most for people managing weekly GLP-1 injections:

• Injection site rotation tracking. Does the app track where you've injected and help you rotate systematically? This is clinically important for preventing lipohypertrophy and ensuring consistent absorption.
• Weekly scheduling. GLP-1 medications are typically dosed once weekly. We evaluated whether each app handles non-daily schedules natively rather than forcing workarounds.
• Dose titration support. Most GLP-1 protocols involve a multi-month dose escalation. We looked for apps that help track where you are in the titration process.
• Multi-medication support. Many GLP-1 users also take oral medications (metformin, oral semaglutide during transitions, vitamins). We evaluated whether each app can manage a mixed regimen.
• Adherence history and data export. Your prescriber needs to see how consistently you've been taking your medication. We looked for apps that build a useful adherence record.
• Practical usability. Setup time, daily friction, notification reliability, and whether the app stays useful after the first month.

We used each app for a minimum of two weeks, set up with a standard weekly GLP-1 injection schedule. Our evaluation prioritized tracking accuracy and daily usability over ancillary features like social sharing or content libraries.

Frequently Asked Questions

What is the best app for tracking GLP-1 injections?

It depends on what you need. For injection site rotation and combined oral+injectable tracking, DoneDose is the strongest option. For food logging alongside GLP-1 tracking, Pep and Weightly are better suited. Shotsy is a solid choice if you want a simple, GLP-1-focused experience without extra complexity.

Do I need a GLP-1-specific app or can I use a general medication tracker?

A general tracker can handle basic reminders, but GLP-1 medications have specific needs — weekly scheduling, dose titration tracking, and injection site rotation — that most general apps handle poorly or not at all. A purpose-built app saves you from workarounds.

Can I track both semaglutide and tirzepatide in the same app?

Yes, if the app supports multiple medications. DoneDose and PepTracker both handle multiple injectable medications with independent schedules. Some GLP-1-specific apps like Shotsy are designed primarily for a single GLP-1 medication at a time.

Should my GLP-1 tracker app also track food and weight?

That depends on your goals. If weight management is your primary reason for taking a GLP-1, apps like Pep and Weightly combine injection tracking with food logging and weight trends. If you want a focused injection tracker without the diet component, DoneDose or Shotsy keep things simpler.

How important is injection site rotation for GLP-1 medications?

Clinically important. Repeated injections in the same site can cause lipohypertrophy, which alters drug absorption and can make your medication less effective. Rotating between abdomen, thigh, and upper arm sites is standard guidance for subcutaneous GLP-1 injections. Our GLP-1 injection site rotation guide covers the full clinical rationale and rotation patterns.

Done Dose tracks GLP-1 injections the way they actually need to be tracked — with visual site rotation, flexible weekly scheduling, and support for your full medication regimen in one place. No food logging gimmicks, no social features. Just reliable injection tracking with a body map that knows where your last shot went. See how Done Dose handles GLP-1 tracking.
