How we compared these apps

Every app below is one we would genuinely recommend for the right person, and every factual claim, from ratings and prices to features and platform support, was checked against the public App Store listing or the developer's website on August 4, 2026. We compared each app on six criteria:

Medication coverage: which GLP-1 medications, pills, and compounded options the app supports
Tracking depth: how well the app handles doses, injection sites, side effects, weight, and nutrition together
Data portability: whether you can export your history and share it with your provider
Pricing transparency: what is free, what is paid, and how clearly that is disclosed
Platform support: iPhone, iPad, Android, Apple Watch, web, and languages
Track record: rating volume, app age, and how actively it is maintained

None of these apps provides medical advice, and estimated medication-level features in any app are informational only. Always follow your prescriber's guidance.

The 5 best GLP-1 tracker apps in 2026

1. Shotsy: Best overall GLP-1 tracker

4.8★ (29,000+ ratings) Free core features iPhone, iPad, Android

Shotsy covers the whole GLP-1 routine in one place: one-tap logging for weekly injections or daily pills, smart reminders and countdowns, injection-site rotation on a visual body map, side-effect logging with pattern detection, and weight, calorie, protein, and water tracking with Apple Health import. It supports every major GLP-1 medication, including Ozempic, Wegovy, Mounjaro, Zepbound, Rybelsus, Saxenda, Victoza, Trulicity, and compounded semaglutide and tirzepatide, and can run multiple medications on separate schedules, which matters if you switch medications or manage a titration plan.

Shotsy's charts and analytics are where it pulls away from the field. Estimated medication-level charts, built from published pharmacokinetic data for semaglutide, tirzepatide, liraglutide, and dulaglutide, show how your medication level rises and fades between doses (clearly framed as estimates rather than measurements), and Shotsy can visualize multiple medications on that chart at once. Progress charts broken down by injection site and by dosage show which sites and dose levels line up with your results; among the other apps here, only Glapp offers anything similar on either front. A maintenance mode, unique to Shotsy, lets you visualize your weight against a target range once you reach your goal. The GLP-1 Journey Recap rounds out the motivational side: a shareable summary of your progress that lets you look back at how far you have come on your treatment journey, designed by GLP-1 users who know how much celebrating wins matters for staying motivated. There is credibility behind the design, too: Shotsy was founded by Aja Beckett, a software engineer who built the app during her own GLP-1 journey, and its Chief Science Officer is Dr. Eric Perakslis, a former FDA Chief Scientist.

Free core tracking with the broadest medication support in the category, including pills and compounded options
Estimated medication-level charts for four GLP-1 molecules, with multiple medications visualized on a single chart
Progress charts by injection site and by dosage, which no other app offers apart from a similar feature in Glapp
Maintenance mode with a target weight range chart for life after goal weight, unique among these apps
Doctor-ready PDF exports of doses, side effects, and weight trends
Home-screen widgets and dose countdowns that reviewers consistently praise
GLP-1 Journey Recap: a shareable, motivating summary of how far you have come
Available in 16 languages on iPhone, iPad, and Android, making it the only app in this list localized beyond English

Requires iOS 18 or later on iPhone, which excludes older devices
Food logging is macro-focused (calories, protein, water), with no photo or barcode meal scanner

結論: The most complete GLP-1 tracker available, with the largest review base in the category (4.8 stars from 29,000+ ratings) and best-in-class charts no other app matches: multi-medication level charts, progress charts by injection site and by dosage, and a maintenance mode chart for life at goal weight. If you want one app for doses, side effects, weight, and provider-ready reports, start here.

2. GlucoPal: Best for progress photos

4.8★ (2,400+ ratings) Free core features iPhone, iPad

GlucoPal (listed as 'Zepbound Tracker by GlucoPal' on the App Store) pairs broad medication coverage with one of the cleanest, simplest designs in the category. Its standout is progress photos: private before-and-after shots with time-lapse animations that make your progress visible even in weeks when the scale barely moves. It covers weekly injections, daily injections, and GLP-1 pills, including compounded semaglutide and tirzepatide and even experimental retatrutide, along with an injection-site rotation map, 14+ GLP-1-specific side effects tied to your dose timeline, estimated medication-level charts, weight trends with weekly averages, milestone celebrations, and CSV exports.

The main limit is analytics depth. GlucoPal has nowhere near as many charts as Shotsy: there are no side-effect correlation charts and no progress breakdowns by injection site or by dosage, so it is harder to see which dose level or routine is actually driving your results. It is also iPhone-only today (Android is 'in development'), and reviewers report mixed accuracy from the photo and barcode meal scanning.

Private progress photos with before-and-after time-lapse animations
One of the cleanest, simplest designs in the category
Broad medication coverage, including daily injections, pills, and compounded options
Estimated medication-level charts and CSV exports

Far fewer analytics charts than Shotsy: no side-effect charts and no progress breakdowns by injection site or by dosage
iPhone only, with no Android app yet
Meal photo and barcode scanning gets mixed accuracy reviews

結論: A clean, friendly tracker with the best progress-photo experience here. The right pick if visual progress and simplicity matter more to you than deep analytics, provided you are all-in on iPhone.

3. Glapp: Best for shot-cycle insights

4.7★ (770+ ratings) Free core features iPhone, Android, web

Glapp's angle is interpretation rather than just logging. Its six-phase 'shot cycle' model maps when semaglutide or tirzepatide peaks and fades in your body, predicting hunger, cravings, and energy dips before they arrive. Daily check-ins for side effects, mood, energy, and sleep feed weekly reports that compare your progress against clinical-trial outcomes, and its 'Wisdom' AI answers questions with citations to peer-reviewed research. Supply tracking with vial volumes and beyond-use dates is unusually strong for compounded and vial users.

The biggest drawback is data portability: Glapp has no export of any kind, neither CSV nor PDF, so you cannot hand your dose and symptom history to a provider, and you cannot take your data with you if you ever want to switch apps. Staying on Glapp is effectively the only way to keep access to your own records. Beyond that, the caveats mostly come down to age: Glapp launched in March 2026, so it has a small review base (4.7 stars from about 770 ratings) and a short track record, the marketing site downplays the Glapp Max subscription that unlocks the full feature set, and the app is English-only.

Shot-cycle model that turns dose timing into practical daily expectations
AI answers grounded in clinical research, with citation links to sources
Best-in-class supply tracking for vials, pens, and beyond-use dates
Works across iPhone, Android, and the web, with Apple Health integration

Very new (launched March 2026) with a small review base
No CSV or PDF export at all, so you cannot share your history with a provider or take your data with you; your records are locked inside the app
The Max subscription is not clearly disclosed on the marketing site; English only

結論: Choose Glapp if understanding your weekly dose cycle matters more to you than ecosystem integrations and you are comfortable adopting a young app while it matures.

4. MeAgain: Best for photo food logging

4.8★ (27,000+ ratings) Free tier + subscription iPhone, iPad, Android

MeAgain wraps GLP-1 medication tracking inside a broader daily companion. Its standout is food logging: capture meals by photo, voice, barcode, or text search, with protein, fiber, and water goals tuned for reduced appetites. It also tracks shots and pills with injection-site history, 18 common GLP-1 side effects with severity ratings, weight, and progress photos, and adds 'Capy,' a friendly capybara AI companion that can also sit on your home screen as a widget.

The trade-offs are worth knowing before you commit. MeAgain has no PDF export, so your dose and symptom history stays inside the app rather than going to your doctor as a report. Subscription pricing is also opaque: the App Store lists price points up to $119.99 with no pricing page on the website. And the app is available in English only.

The most flexible food logging of any GLP-1 app: photo, voice, barcode, and search
Large review base (4.8 stars from 27,000+ ratings) and an active community
Covers injectables and the newest oral GLP-1s, regardless of prescription source
Capy, the capybara companion, adds personality and a fun home-screen widget

No PDF export, so dose, symptom, and weight history cannot be handed to your doctor as a report
Opaque subscription pricing, with App Store price points up to $119.99
English only

結論: The best pick if photo-based food logging is your single most important feature and you don't need doctor-ready exports.

5. Pep: Best for peptides beyond GLP-1s

4.7★ (2,700+ ratings) Subscription required iPhone, Apple Watch, Mac, Android

Pep casts a wider net than the other four apps. Alongside GLP-1 dose logging, it serves the broader peptide world with a reconstitution calculator, vial inventory with photos and lifespans, a research library covering 75+ compounds, and estimated half-life and peak-timing charts. An AI meal scanner, hydration and sleep tracking, and mood check-ins round it out, and it is the only app on this list with a real Apple Watch app.

The trade-offs are significant for GLP-1-only users. There is no functional free tier: a subscription (from $3.99 per week) is required for core tracking. It is also English-only and carries a 17+ age rating.

Peptide-native tools no GLP-1-only app offers: reconstitution math, vial inventory, compound library
Widest Apple ecosystem support here, including a true Apple Watch app
AI meal scanning plus hydration, sleep, and mood tracking in one place

No real free tier, since core tracking requires a subscription, from $3.99 per week
English only, with a 17+ age rating

結論: If you track multiple research peptides rather than just a GLP-1, Pep is the specialist worth paying for. For GLP-1-only tracking, the free options above cover more.

The verdict

Any of these five apps beats a generic calorie counter for a GLP-1 journey, because they understand doses, injection sites, and side effects in a way food apps never will. But for most people, Shotsy is the best overall choice in 2026: it combines the deepest medication coverage, analytics no other app matches (multi-medication level charts, progress charts by injection site and by dosage, and a maintenance mode for goal weight), doctor-ready exports, and the largest review base in the category, with core features that are free on both iPhone and Android.

Best GLP-1 tracker apps: frequently asked questions

What is the best GLP-1 tracker app?

Shotsy is the best overall GLP-1 tracker app in 2026, rated 4.8 stars from more than 29,000 App Store ratings. It combines dose logging for every major GLP-1 medication, estimated medication-level charts, side-effect and weight tracking, and doctor-ready PDF exports, with free core features on iPhone and Android. (Shotsy is our app; the comparison above shows exactly how the alternatives stack up.)

What is the best free GLP-1 tracker app?

Shotsy offers the most complete free tier: dose logging, reminders, injection-site rotation, side effects, and weight tracking are all free. GlucoPal is a strong free alternative with a clean, simple design, and Glapp's core tracking is also free. Pep is the exception, since it requires a subscription for core tracking.

Which GLP-1 tracker apps work on Android?

Shotsy, MeAgain, and Glapp all offer Android apps today. GlucoPal is iPhone-only with an Android version listed as in development.

Can a tracker app tell me my exact medication level?

No. Apps like Shotsy, GlucoPal, Glapp, and Pep estimate medication levels using published half-life data for semaglutide and tirzepatide. These charts are a useful way to understand why appetite and side effects shift across the week, but they are estimates, not measurements. No tracking app provides medical advice; always follow your prescriber's guidance.

Which GLP-1 apps can export a PDF report for my doctor?

Shotsy can export your dose, side-effect, and weight history as a PDF report to share with your healthcare provider, and GlucoPal offers CSV exports of your history. MeAgain does not offer PDF export, and Glapp has no export at all, so your data stays inside the app.

Do I need a GLP-1-specific app instead of a calorie counter?

If you take a GLP-1 medication, a dedicated tracker is worth it. Generic food apps don't track doses, injection-site rotation, titration schedules, or side-effect patterns, which are the things your prescriber actually asks about. GLP-1-specific apps like Shotsy also set nutrition goals around protein and hydration rather than calorie restriction, which matches how GLP-1 treatment works.

What is the best app for tracking Ozempic, Wegovy, Mounjaro, or Zepbound?

Shotsy is the best app for tracking any major GLP-1 medication, including Ozempic, Wegovy, Mounjaro, Zepbound, Rybelsus, Saxenda, Victoza, Trulicity, and compounded semaglutide or tirzepatide. It can even track more than one medication at a time, which helps if you switch. Every app in this comparison supports the core semaglutide and tirzepatide brands.
