Last updated: June 10, 2026 · Retested quarterly and after major app releases

At a Glance: The 7 GLP-1 Tracker Apps Compared

Feature coverage based on publicly available app descriptions as of May 2026. See each app's App Store listing for current details.

How We Ranked These Apps

We retest the full GLP-1 tracker app lineup quarterly and after major release events. Rankings reflect a combination of GLP-1-specific capability coverage, real-world usability across compounded and branded protocols, and what GLP-1 users actually use day-to-day.

Our weighting criteria for GLP-1 trackers:

• GLP-1 dose calculation (25%): Does the app handle reconstitution math for compounded semaglutide, tirzepatide, and retatrutide? Most generic trackers don't.
• Side effect tracking (20%): Nausea, fatigue, constipation, sulfur burps, injection-site reactions. The subjective layer most apps ignore.
• Lab and biomarker integration (15%): Can you log A1c, fasting glucose, lipids, and watch them move with the protocol?
• Titration support (15%): Built-in escalation schedules for branded GLP-1s, plus flexibility for compounded protocols.
• Wearable integration (10%): Apple Health, Google Health Connect, Apple Watch sync for weight, RHR, sleep.
• Multi-compound support (10%): Roughly 35% of GLP-1 users also track at least one research peptide. Single-category trackers leave that population underserved.
• Pricing and access (5%): Free tier capability, paid tier value, no-signup friction.

Data sources:

• Direct testing of each app on iOS and Android (last full retest: May 18, 2026)
• App Store and Play Store ratings as of May 18, 2026
• GLP-1 community surveys conducted in Q1 and Q2 2026 across r/Tirzepatide, r/Semaglutide, r/Mounjaro, r/Wegovy, r/RETA, and r/Ozempic
• Anonymized usage patterns from the Regimen user base (aggregated as percentages and rankings only, never as user counts)

Conflicts of interest: Regimen is published by Awaken Labs LLC and rates itself in this list. We have not received compensation from any other app reviewed. Rankings for competing apps reflect publicly available capability comparisons and community sentiment, not commercial arrangements.

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 nothing held back. The features other apps charge for, you get for nothing, including the ones behind Shotsy's ~$9.99/mo premium: medication-level curves (your estimated semaglutide or tirzepatide between doses) and Apple Health / Google sync (weight, body fat, resting heart rate, blood pressure).

Then the depth no other GLP-1 app comes close to: 50+ daily check-in markers. Not just the obvious appetite and nausea, but the ones every other app ignores, alcohol cravings, nicotine cravings, hair shedding, water retention, mood and anxiety, the things people on GLP-1s actually notice. Plus lab/bloodwork logging (A1c, fasting glucose, lipids), photo progress tracking, and a built-in reconstitution calculator for compounded semaglutide, tirzepatide, and retatrutide.

What turns all that into answers is the Signals engine. It triangulates your doses, your check-in markers, your labs, and your synced health metrics to surface patterns you'd never catch on your own, and it compares your trajectory against the GLP-1 clinical studies (the thing people love Glapp for, across far more of your data).

And if you're coming from Shotsy, Regimen imports your Shotsy history, so you don't start over.

What it does best: the most complete GLP-1 picture, free, medication levels + health sync + 50+ markers + labs, all connected by the Signals engine.

Where it falls short: no built-in food, macro, or water logging (Shotsy and MeAgain do that), and a smaller review base than Shotsy.

Best for: anyone who wants to truly understand their GLP-1 journey, not just log shots, for free.

2. Shotsy

Shotsy is the most popular GLP-1 tracker by a wide margin, ~24,000 reviews, years in the App Store, and a genuinely polished app. The free tier covers the basics well: dose logging, injection-site rotation, weight charts, side effects, and food/protein/water tracking (something Regimen doesn't do). If you want the app everyone's on and a clean lifestyle logger, it's an easy pick.

The catch is depth. The features people most want for understanding their response, estimated medication-level curves and Apple Health sync, sit behind Shotsy's premium tier at $9.99/mo (as of this writing).

What it does best: scale, polish, and built-in food, macro, and water logging.

Where it falls short: medication levels and health sync are paywalled; GLP-1 only (no peptides or TRT); no lab tracking.

Best for: someone who wants the most popular app, likes logging food and macros, and doesn't mind paying for the deeper features.

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 GLP-1 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 medication-level graphs and clean comparisons against the GLP-1 clinical studies, in a polished web app.

Where it falls short: no photo progress tracking, no lab tracking, and web-only (no native push notifications, no Apple Health integration, no offline access).

Best for: people who want the graphs and study comparisons.

4. MeAgain

MeAgain is a strong all-in-one lifestyle dashboard for GLP-1 users, food, water, protein, steps, and side effects bundled with shot logging, reminders, and progress tracking. It has a large, well-rated user base and a clean focus on the daily lifestyle side of weight loss.

What it does best: built-in food, water, protein, and steps tracking alongside GLP-1 shots, in one dashboard.

Where it falls short: iOS only, no medication-level curves, no lab tracking, no multi-compound support.

Best for: someone who wants the food and nutrition side bundled with shot tracking.

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 ~24,000, 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: Patterns From Regimen Data

These patterns come from anonymized aggregate usage across the Regimen user base. Percentages and rankings only, no individual user data.

• GLP-1 medications are the most-tracked compound category on Regimen, appearing on roughly half of all active user dashboards. Among the GLP-1s, retatrutide is the most commonly logged, followed by tirzepatide and semaglutide.
• ~35% of GLP-1 users also track at least one research peptide simultaneously. Once people start running GLP-1s, a third branch into peptide stacking, usually for healing, recovery, or aesthetic goals.
• ~25% of all Regimen users run a peptide + GLP-1 combo. This is the body recomposition pattern: a weight-loss agent paired with a recovery peptide.
• ~10% of all Regimen users run a GLP-1 + TRT combo. This is the protocol for men optimizing body comp while on TRT.
• Only 34% of compound doses are daily. The rest are weekly, twice-weekly, every-3.5-days, or specific-day schedules. A GLP-1 tracker isn't a daily-pill app, it's an injection scheduler.
• ~15% of users have at least one compound running on a cycle (weeks on, weeks off). Most cycling happens around peptide protocols, but some users cycle GLP-1s seasonally too.

The takeaway for picking a GLP-1 tracker: if you're only on one branded GLP-1, almost any tracker works. But if you're on a compounded protocol, running multiple compounds, or pairing your GLP-1 with TRT or peptides (which is roughly 35-45% of GLP-1 users), the cost of a single-category tracker compounds quickly. Calculator, labs, markers, and schedules need to live in the same place.
