Which GLP-1 tracker app fits you in 2026?

There is no single right app for everyone. There is a right app for what you are tracking. If you want a mature, injection-focused tracker, Shotsy is well built. If you want a free-to-download tracker that already covers doses, levels, sites, side effects, nutrition, and progress photos, Pep does a lot. Regimen is a strong pick if you track GLP-1 alongside peptides or TRT. Mingo adds Dexcom G7 integration and a playful flamingo companion. Glapp is free, ships an Apple Watch app, and leans into clinical-trial benchmarking and AI Q&A. Phaze is GLP-1-specific and adds Labs & Scans across 8 categories, Body Composition (Beta) with DEXA import, an Apple Watch app, AI Meal Snap, and a free Estimated Levels chart, with AES-256-GCM encrypted medical data. Pick the one whose feature list matches the parts of your GLP-1 you actually want data on.

Phaze vs Shotsy vs Pep, how do they compare?

All three are GLP-1 trackers, and they overlap a lot. Shotsy is free to download with optional premium, on iOS and Android, strong on injection rotation and dose tracking, with an Estimated Medication Levels chart, nutrition logging, widgets, and PDF export. Pep is free to download with optional premium, on iOS and Android, and covers doses, estimated levels, injection sites, side effects, nutrition with an AI food scanner, and progress photos. Phaze covers doses, side effects, weight, food (with AI Meal Snap), Labs & Scans across 8 categories, Body Composition (Beta) with DEXA import, a free Estimated Levels chart, and an Apple Watch app, in 8 languages, with AES-256-GCM encrypted medical data. Honest edges for Phaze are labs, DEXA/body composition, and the Apple Watch app; Pep's listing does not mention those. If you mainly inject, Shotsy is a clean choice. If you want a broad free-to-download tracker, Pep does well. If you also want labs, body composition, or the watch app, Phaze is the broader fit.

Which app works well for Mounjaro?

Mounjaro is tirzepatide, the same molecule as Zepbound, labeled for type 2 diabetes. Any tracker that supports tirzepatide will work. Shotsy covers Mounjaro doses well and supports both injectable and oral GLP-1s. Pep covers Mounjaro doses, estimated levels, injection sites, side effects, and nutrition for free to download. Regimen and Glapp both support tirzepatide too. Phaze supports Mounjaro and Zepbound across its features, with weekly dose cadence, a tirzepatide titration schedule, structured side-effect logging, an Estimated Levels curve based on published pharmacokinetics, and Labs & Scans where you can watch A1C, lipids, and kidney markers over time next to your dose history. Phaze includes an Apple Watch 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 a few lab snapshots a year is enough to keep track of a GLP-1. 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 dose reminders that 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. None of these apps, Phaze included, provide medical advice, so keep your prescriber in the loop either way.

Which GLP-1 trackers are good on iPhone?

On iPhone you have several solid options. Shotsy is polished and strongest on injection rotation and dose tracking, with widgets and PDF export. Pep is free to download and already covers doses, estimated levels, sites, side effects, nutrition, and progress photos. Glapp is free, ships an Apple Watch app, and leans into clinical-trial benchmarking and AI Q&A. Phaze covers doses, side effects, weight, food (with AI Meal Snap), Labs & Scans across 8 categories, Body Composition (Beta) with DEXA import, and an Apple Watch app with widgets and Live Activities, with encrypted iCloud backup. They all work with Apple Health for weight and activity. If you only need a clean injection tracker, Shotsy is a strong pick. If you want labs and body composition in the same app as your doses, Phaze is the broader fit. The watch app is the differentiator many people underrate, since logging a dose from the wrist takes a few seconds, and Phaze and Glapp both have one.

Which GLP-1 trackers are good on Android?

Most well-known GLP-1 trackers are now cross-platform. Shotsy, Pep, Regimen, Mingo, and Glapp all list iOS and Android. Pep covers doses, estimated levels, sites, side effects, nutrition, and progress photos on Android. Mingo adds Dexcom G7 integration. Glapp is free and also offers a browser version. Regimen is a broad multi-compound tracker on both platforms with Google Health Connect support. Phaze is currently iOS-first, so if Android is a hard requirement, check Phaze's store listing for the latest availability and compare the apps above. Health Connect integration on Android is still uneven across these apps and improves with each release, so verify the current store description before you commit.

PHAZE GUIDES

GLP-1 tracker apps, 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 can follow. The 2026 picture has Shotsy, Pep, Regimen, Mingo, Glapp, and Phaze among the realistic, well-known options. This guide describes what each one does, then explains where Phaze adds depth, using the criteria that matter for the medication you are actually on. Phaze is a wellness and habit-tracking app, not a medical device, and none of these apps provide medical advice.

What to look for in a GLP-1 tracker

A GLP-1 tracker usually covers several things. Dose tracking with weekly cadence and step-up dates, ideally with an estimate of how the drug 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 and a way to spot patterns across weeks. Protein-first nutrition, because GLP-1 makes appetite small and protein adequacy is what helps protect lean mass. AI meal scanning plus barcode and voice input, because typing every meal is what kills consistency. Lab tracking, since some people watch their bloodwork change alongside the medication. Body composition, since weight on its own can hide muscle changes. A watch app that lets you log a dose or weight from the wrist. Strong encryption, because medical data should never be sold. And support for the medication you are on: Ozempic, Mounjaro, Wegovy, Zepbound, plus compounded and 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 people are bad at remembering recurring weekly actions. Side-effect logging is second because the side-effect timeline (which week of which dose, how severe) 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 while you eat less. Lab and body-composition tracking round out the picture for people who want it, 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-language support, because GLP-1 use is global and English-only apps leave many users behind. A way to share your data with a clinician. None of these are dealbreakers on their own, but their absence quietly makes the app worse.

The honest landscape, 2026 edition

Shotsy (Shotsy Co.) is an injection-first app many people in the GLP-1 community know. It tracks doses and injection-site rotation, supports both injectable and oral GLP-1s, and includes side-effect logging, weight charts, basic nutrition logging (calories, protein, water), an Estimated Medication Levels chart, home-screen widgets, PDF export for clinicians, and Apple Health sync. It is free to download with an optional premium subscription, on iOS and Android, in 17 languages, and is well rated. If your main question is about the shot, Shotsy is a mature, capable choice.

Pep (GLP 1 Tracker: Pep, by Shred Apps) is a free-to-download GLP-1 tracker with optional premium. Despite the lightweight feel, its App Store listing describes a broad feature set: dose tracking for injections and oral pills, an estimated medication-level indicator, injection-site rotation, side-effect logging, nutrition with an AI food scanner, progress photos, hydration, reminders, and Apple Health support, on iOS and Android. It overlaps heavily with Phaze. Its listing does not mention lab/bloodwork tracking, DEXA import, or an Apple Watch app.

Regimen (Regimen: Peptide Tracker, by Awaken Labs LLC) is a broad multi-compound tracker covering peptides, TRT, HRT, GLP-1, and supplements, on iOS and Android. For GLP-1 it offers dose logging, injection-site rotation, medication-level visualization with half-life plotting, lab/bloodwork tracking, progress photos, and daily check-in markers, plus built-in calculators. It is freemium (a free tier for one compound, plus paid Premium and a free trial). A fair contrast is that Phaze is GLP-1-specific while Regimen spans many compounds; Regimen's App Store listing does not list an Apple Watch app.

Mingo (by Agora Labs) is a GLP-1 tracker on iOS and Android with AI food logging (photo, barcode, voice), shot tracking and reminders, a medication-level estimator, a "Journey Card" with progress photos, side-effect monitoring, weight charts, Apple Health sync, and Dexcom G7 (CGM) integration. It includes a Tamagotchi-style flamingo home-screen companion and supports 12 named medications including compounded semaglutide and tirzepatide. It is free to download with paid premium plans. Its listing does not advertise an Apple Watch app.

Glapp (Glapp — Smart GLP-1 Tracker, by Glapp, Inc.) is a free GLP-1 tracker on iOS and Android, with an Apple Watch app and an optional browser version. It offers shot logging with reminders, titration support, injection-site rotation, a "shot phase" / medication-level visualization, weight tracking, side-effect and daily check-in logging, supply tracking, peer and published clinical-trial benchmarking, and "Glapp Wisdom" AI Q&A. It is currently free with no premium tier, in English. It is a close, feature-overlapping competitor.

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 Phaze does not.

Where Phaze fits

Phaze covers the same dose, side-effect, weight, and food story as the others, and adds a few things some GLP-1 trackers leave out. We will not pretend Phaze is alone on every feature, because it is not.

Labs & Scans across 8 biomarker categories (GLP-1, metabolic, lipids, vitamins, kidney, liver, thyroid, and inflammation), with manual entry free and lab-document OCR import in Phaze Pro, and trend charts you can read next to your dose history. The Lab Tracker feature page walks through it. Regimen also tracks bloodwork, so this is depth, not exclusivity.

Body Composition (Beta) as part of Labs & Scans: an AI photo estimate of body fat percentage and muscle mass with a confidence level and a roughly 3 to 5 percent margin of error, plus DEXA scan import. See body composition.

A real Apple Watch app, plus Home and Lock Screen widgets and Live Activities, so you can log a dose, weight, or water from the wrist. Glapp also ships an Apple Watch app; Phaze and Glapp are the two here that clearly do. The Apple Watch GLP-1 tracker guide covers what the Phaze watch app does.

AI Meal Snap plus label, barcode (via OpenFoodFacts), and voice or text input, with protein-first nutrition and fiber as a first-class goal. Manual entry and barcode are free; unlimited AI scanning is Phaze Pro.

Estimated Levels, a pharmacokinetic curve showing your dose building, peaking, and tapering across the cycle, based on FDA prescribing information for established medications and Phase 3 clinical trial data for newer molecules. It is free, and it is for information only, not medical advice.

14 medication options including Ozempic, Mounjaro, Wegovy, Wegovy Pill, Zepbound, Rybelsus, and compounded and investigational molecules, with injectable and oral flows. Several newer molecules are investigational and not FDA-approved as of 2026; Phaze is a tracking tool and does not supply, prescribe, or recommend any medication.

8 languages including English, Portuguese, Spanish, French, German, Japanese, Simplified Chinese, and Arabic.

Medical data (doses, side effects, notes, injection sites) is encrypted with AES-256-GCM in the Apple Keychain and is not uploaded to our servers by default. Optional iCloud backup is also encrypted, and medical data is excluded from data exports.

The free core covers dose tracking, the Estimated Levels chart, side-effect logging, weight, check-ins, and meal logging by voice, barcode, and manual entry. Lab OCR import, DEXA import, unlimited AI meal scanning, and the doctor PDF report are part of Phaze Pro.

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

iPhone vs Android

Most realistic GLP-1 trackers shipped on iPhone first, but the platform picture in 2026 is mostly cross-platform. Shotsy, Pep, Regimen, Mingo, and Glapp all list both iOS and Android. Phaze is currently iOS-first; check the store listings for the latest availability before you commit, since this changes release to release.

Apple Watch is where the field thins out. Phaze and Glapp both ship an Apple Watch app. Pep's, Mingo's, and Regimen's App Store listings do not list an Apple Watch app, and Shotsy's watch support could not be verified. If logging a dose from the wrist is the main thing you want, that narrows the choice. Wear OS support for Android lags Apple Watch across this category.

For a simple decision rule: if you want an Apple Watch app, Phaze or Glapp clearly have one. If you want labs and DEXA import alongside doses, Phaze and Regimen both track labs, with Phaze adding DEXA import and body-composition estimates. If you switch platforms during your GLP-1 journey, pick a tracker that exists on both, otherwise migration becomes a manual export and import.

Apple Health and Health Connect integration is common but uneven across this category. Phaze reads weight, steps, and workouts from Apple Health. Shotsy, Pep, Regimen, and Mingo all describe Apple Health support; Regimen also lists Google Health Connect. Always check the current store description for the integration list, since it changes between releases.

Free vs premium tradeoffs

What is reasonable to keep 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, and also keeps the Estimated Levels chart free.

What is reasonable to charge for: lab-document OCR import (real engineering and per-scan compute), DEXA import, unlimited AI meal scanning, the doctor PDF report, and advanced trends. Phaze charges for those through Phaze Pro, with monthly and yearly options; the live price is set in the App Store and Google Play. The pricing models across the field vary a lot: Glapp is currently free with no premium tier, Pep and Mingo are free to download with optional premium, Shotsy is free to download with optional premium, and Regimen is freemium with a free tier and a free trial. Several of these do not publish a single clear premium price, so compare the live store listings rather than a quoted number. The App Store category and Google Play category make that easy.

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 and OCR are the parts worth paying for.
