What's the best GLP-1 tracker app in 2026?

There is no single best app for everyone. There is a best app for what you are tracking. If you want injections plus a clean injection map and you are on iPhone, Shotsy is well built. If you want a free, simple dose and weight tracker, Pep covers that. If you want labs, DEXA, AI food scan, an Apple Watch app, and Android parity in one place, Phaze covers all of that. The honest 2026 picture has Shotsy, Pep, Regimen, Mingo, Glapp, and Phaze as the realistic options. Pick the one whose feature list matches the parts of your GLP-1 you actually want data on, instead of a generic weight app stretched to fit.

Phaze vs Shotsy vs Pep, which is best?

Shotsy is iPhone-first, paid, and excellent at injection rotation and dose tracking. Pep is free, simple, and covers doses and weight without much else. Phaze covers doses, side effects, weight, food (with AI scan), labs (40+ biomarkers, photo and PDF OCR), DEXA body composition, and a real watchOS app, on both iPhone and Android, in 8 languages. Side-effect logging in Phaze is structured, with severity and timeline, not a free-text note. If you only inject and you are on iPhone, Shotsy is good. If you only want doses plus weight for free, Pep is fine. If you also care about labs, body composition, watchOS, or Android, Phaze is the broader fit. Try free first, all three offer it.

What's the best app for Mounjaro?

Mounjaro is tirzepatide, the same molecule as Zepbound, just labeled for type 2 diabetes. Any tracker that supports tirzepatide as a medication will work. Shotsy covers Mounjaro doses well on iPhone. Pep covers it for free with weight. Phaze supports Mounjaro and Zepbound across all features, with weekly dose cadence, the right step-up schedule (2.5 to 5 to 7.5 to 10 to 12.5 to 15 mg), structured side-effect logging, and a Mounjaro-aware lab tracker that watches A1C, lipids, and kidney markers respond to the dose. Phaze runs on iPhone and Android, with a watchOS app for wrist logging. Pick by which features actually matter to you on Mounjaro, not by which app says Mounjaro most often.

Do I really need a GLP-1 app?

Honestly, no. A paper notebook with the date of every injection, the dose, side effects, weekly weight, and four lab snapshots a year is enough to manage a GLP-1 well. People have done it for decades. What a GLP-1 app adds is automation: dose reminders, side-effect patterns over months, lab values trended on charts, body composition layered next to weight, and a watch face that lets you log without picking up your phone. If you like notebooks, keep the notebook. If you want the trend lines drawn for you and the dose reminders to sit on the right day automatically, an app saves time. Phaze is free for the core tracking parts, so the cost of trying is zero.

What's the best GLP-1 tracker on iPhone?

On iPhone you have real options. Shotsy is paid, polished, and strongest on injection rotation and dose tracking. Pep is free and fine for doses and weight. Phaze covers doses, side effects, weight, food (with AI scan), labs with photo and PDF OCR, DEXA body composition, and a watchOS app with complications, all with iCloud encrypted backup. If you only need a clean injection tracker, Shotsy is the cleanest pick. If you want labs and DEXA in the same app as your doses, Phaze is the broader fit. Both work with Apple Health for weight and activity. The watch app is the differentiator most people underrate, since logging a dose from the wrist takes about three seconds.

What's the best GLP-1 tracker on Android?

Android has fewer options because most GLP-1 trackers shipped iOS first. Shotsy and Regimen are iPhone-only. Pep covers Android with a lighter feature set. Mingo and Glapp ship Android too. Phaze runs on Android with feature parity for dose, side-effect, weight, food, and lab tracking, plus a Wear OS companion (smaller than the watchOS app). If you are on Android and want labs, DEXA, food scan, and dose tracking in one app, Phaze is currently the broadest fit on the platform. If you want a simple free dose log, Pep on Android works fine. Health Connect integration on Android is still uneven across these apps, including Phaze, and is improving with each release.

Which GLP-1 tracker has an Apple Watch app?

Phaze and Shotsy both ship a real Apple Watch app, with different focus. Shotsy on the watch leans on injection logging and dose reminders, in line with its iPhone strengths. Phaze on the watch covers dose logging, weight entry, water, fasting timer, and complications you can put on a watch face for one-tap dose, weight, or water. Phaze on watchOS works without your iPhone for log-only tasks once it is set up. Pep, Mingo, Regimen, and Glapp do not ship a full watch app at the time of writing, though some have notification mirroring. The Apple Watch GLP-1 tracker guide on this site covers what the Phaze watch app does in more detail.

Which GLP-1 tracker tracks labs and DEXA?

At the time of writing, Phaze is the GLP-1 tracker that covers labs and DEXA as first-class features. Lab tracking is photo and PDF OCR for 40+ biomarkers including A1C, lipids, kidney, liver, thyroid, vitamin D and B12, with each value on its own chart and your dose overlaid. DEXA body composition imports from a scan PDF, with Bod Pod and smart scale also supported on the same chart. Manual lab entry is free, photo and PDF scanning are Premium. Shotsy, Pep, Regimen, Mingo, and Glapp do not currently cover labs or DEXA at this depth, though some let you note a single value. Lab data is AES-256-GCM encrypted, never sold, never used to train AI.

PHAZE GUIDES

Best GLP-1 tracker app, an honest 2026 comparison

A GLP-1 tracker is its own category, separate from generic weight or food apps, because the medication adds new things to track: weekly doses, injection sites, side effects, dose changes, and the lab and body-composition shifts that follow. The 2026 picture has Shotsy, Pep, Regimen, Mingo, Glapp, and Phaze as the realistic options. This guide names what each one does well, then shows where Phaze leads, with the criteria that matter for the medication you are actually on.

What to look for in a GLP-1 tracker

A real GLP-1 tracker covers nine things. Dose tracking with weekly cadence and step-up dates, ideally with a sense of how the drug actually behaves over time so reminders sit on your real injection day, not a calendar copy. Side-effect logging that goes beyond a free-text note, with severity, body region, and a way to spot patterns across weeks. Protein-first nutrition because GLP-1 makes appetite small and protein adequacy is what protects lean mass. AI food scan plus barcode and voice input, because typing every meal is what kills consistency. Lab tracking, since the proof of whether the medication is working is in your bloodwork, not the scale. Body composition, ideally with DEXA import, since weight on its own hides muscle loss. A watch app that lets you log a dose or weight from the wrist. End-to-end encryption, because medical data should never be sold. And multi-medication support: Ozempic, Mounjaro, Wegovy, Zepbound, plus compounded semaglutide and tirzepatide and the newer molecules.

The order of those criteria is not arbitrary. Dose tracking is the floor of any GLP-1 tracker because the medication is a recurring weekly action, not a daily one, and humans are bad at remembering recurring weekly actions. Side-effect logging is second because the side-effect timeline (which week of which dose, how severe, in which body region) is the part most people forget when they finally talk to their prescriber, and a structured log replaces a guess. Nutrition is third because once appetite drops, the question is no longer how to eat less, it is how to keep enough protein to hold lean mass while you eat less. Lab tracking is fourth because the bloodwork is what tells you whether the medication is doing its job, and most apps in this category quietly skip it. Body composition, watch, encryption, and medication breadth are fifth through ninth because they round out the picture without being the entry point.

A good tracker also gets the small details right. Reminders that respect timezone changes during travel, since a GLP-1 user who flies on dose day still needs the dose. Apple Health and Health Connect integration so weight from your scale shows up automatically. Multi-currency and multi-language support, because GLP-1 use is global and the apps that ship English only leave most users behind. Export to CSV or PDF, so your data is not locked in. None of these are dealbreakers on their own, but their absence quietly makes the app worse.

The honest landscape, 2026 edition

Shotsy is the injection-first app most people in the GLP-1 community know. It does dose tracking and injection-site rotation well, with a clean UI and a useful injection map that visually rotates abdomen, thigh, and upper arm sites for you. Side-effect logging is solid, with severity and a body-region picker. It is paid, iPhone-only, and stays inside the injection use case rather than nutrition, labs, or body composition. If your tracking question is mostly about the shot, Shotsy is well built.

Pep is a free, lighter alternative focused on doses and weight. The free tier is generous and the app is easy to set up in a few minutes. It does less than Shotsy on injection rotation and side effects, and it does not try to cover food, labs, or watch. Pep is a fair pick for a first GLP-1 tracker, especially if you do not want to spend money to find out whether tracking helps you stick with the protocol.

Regimen is an Australia-focused GLP-1 tracker that pairs nicely with the Australian telehealth market. It covers doses, side effects, and weight, with a clinician-flavored framing of the data. Outside Australia it is less discoverable, and the watchOS and lab story is thinner than what Shotsy or Phaze do. If you are in that market, it is a reasonable fit; outside it, you will likely choose between Shotsy, Pep, and Phaze.

Mingo is a basic GLP-1 logger, free to start, with simple dose and weight entry. It is fine if you want a notebook in app form, without much opinion about how to track. The visual design is plain and the depth of features is modest. People who pick Mingo often graduate to a more featureful app within a few months.

Glapp has a longer history in this space and a user base that came from the early GLP-1 wave. The visual feel is older and the modern AI food scan and lab pieces are not part of the core experience. There is value in maturity, and Glapp ships features other apps still consider novel, but the design conventions feel a generation behind 2026 mobile UI.

Phaze, the app behind this site, is the comparison anchor below. We will be specific about what Phaze does, and equally specific about where the alternatives above do something better.

Where Phaze leads

Phaze covers the same dose, side-effect, weight, and food story as the others, then adds the things most GLP-1 trackers leave out.

Lab tracking with photo and PDF OCR, 40+ biomarkers per chart, with your dose overlaid so a step-up shows up next to the value change. The Lab Tracker feature page walks through it.

DEXA body composition import, plus Bod Pod and smart scale, on a single body-composition chart with weight and lean mass on the same timeline. See body composition.

A real watchOS app with complications, dose logging from the wrist, and watch-side weight entry. The Apple Watch GLP-1 tracker guide covers what the watch app actually does.

AI food scan plus barcode and voice input, with protein-first nutrition rather than pure calorie counting. The food scan is paid, manual entry and barcode are free.

15 medications including Ozempic, Mounjaro, Wegovy, Zepbound, compounded semaglutide and tirzepatide, plus the newer investigational molecules people are asking about.

8 languages including English, Portuguese, Spanish, French, German, Italian, and more, instead of English-only.

AES-256-GCM encryption on device and in iCloud backup. Even Apple cannot read your medical data. Lab and dose data is never sold and never used to train AI.

Free core covers dose tracking, side-effect logging, weight, and basic food entry. Photo and PDF lab scanning, AI food scan, DEXA OCR, and advanced trends are Premium.

Side-effect logging deep dive: does Phaze track side effects?

iPhone vs Android

Most of the realistic GLP-1 trackers are iPhone-first because Apple Health and the App Store community happened earlier in this category. Shotsy and Regimen are iOS-only at the moment. Pep and Mingo have iOS and limited Android coverage. Glapp covers both with feature gaps.

Phaze is on iPhone and Android with feature parity for dose, weight, food, and side-effect tracking. The watchOS app is iPhone-only because watchOS is iPhone-only by definition. Wear OS support for Android lags Apple Watch on every GLP-1 tracker right now, including Phaze. If you wear a Wear OS watch and dose logging from the wrist is the main thing you want, none of the GLP-1 trackers fully solve that problem yet, and the realistic answer is to log on the phone.

For a simple decision rule, if you are on iPhone and you want a watch on your wrist, Phaze or Shotsy. If you are on Android, Phaze or Pep. If you want labs and DEXA on either platform, only Phaze covers it natively. If you switch platforms during your GLP-1 journey (a not-uncommon move during a phone upgrade), pick a tracker that exists on both, otherwise migration becomes a manual export from one app and import into another.

Apple Health and Health Connect integration is uneven across this category. Phaze reads weight from Apple Health on iOS and from Health Connect on Android, so a smart scale you already use stays useful. Shotsy reads from Apple Health. Pep, Mingo, and Regimen vary by version. Always check the current store description for the integration list before you commit, since it changes release to release.

Free vs premium tradeoffs

What should be free in a GLP-1 tracker: dose logging, weekly cadence, side-effect notes, weight, basic food entry, and viewing your own trends. Charging for any of those turns the app into a barrier in front of medical data the user already owns. Phaze keeps all of those free.

What is reasonable to charge for: lab OCR (real engineering and per-scan compute cost), DEXA OCR, AI food scan with grams and macro estimates, advanced body-composition trends, and cloud backup with encryption. Phaze charges for those, with a one-time and a yearly option, and the App Store and Google Play keep store reviews honest. The App Store category and Google Play category make it easy to compare against the alternatives.

The rule of thumb is simple: if a free tier hides your own dose history, weight, or side-effect notes behind a paywall, that is the wrong tier design. The medical data is yours, the AI processing is the part worth paying for.
