Best GLP-1 tracker apps in 2026: Shotsy, MeAgain, Pep, Glapp and more compared

What a GLP-1 tracker should do

Reviews of these apps keep coming back to the same short list. Before comparing apps, it helps to know which of these matter to you:

• Dose log and reminders. Every app here does this. Check that it supports your schedule (weekly, daily pill, every 10 days) and your medicine, including compounded versions if you use them.
• Injection site rotation. Suggests the next site so you don't keep using the same spot.
• Estimated medication level. A curve built from the medicine's published half-life and your logged doses. It is an estimate, not a blood test.
• Weight, side effects and food. Weight logging is the habit with the best evidence behind it.⁸ Food logging ranges from a protein number to a full food database.
• A report for your care team, and a way to export your data.

The apps at a glance

Shotsy

The best-known dedicated tracker, with about 34,000 App Store ratings at 4.8 stars.¹ It logs shots and daily pills, weight, calories, protein, water and side effects, supports several medications at once, imports from Apple Health, and its website lists a site map that suggests the next injection site, titration planning and a PDF export for your care team. In our own test of the Android app on November 4, 2026, logging stayed free, while the level chart, Health Connect import and widgets sat behind Shotsy+. Its App Store privacy label lists no data used to track you. Best for: a polished, all-round shot tracker.

MeAgain

The most-rated app here, with about 40,000 ratings at 4.8 stars.² Its website says the free version has no time limit and includes the shot log, reminders, medication-level graph, side effects and food logging. Premium adds progress photos, journey cards, a widget and unlimited chat with Capy, an AI companion that also works over iMessage. Food can be logged by photo, barcode or search. Its privacy label is the broadest of the dedicated trackers: identifiers and usage data are listed as used to track you. It is English only. Best for: people who want food logging and a chatty AI companion.

Pep

A smaller app (964 ratings, 4.7 stars) with a long feature list: level estimates, site rotation, dose escalation, side effects on a calendar, body measurements and side-by-side progress photos, an AI food photo scanner, smart-scale sync and cloud backup.³ It supports compounded semaglutide, tirzepatide and retatrutide. The listing does not say which features are free. Best for: people who want photos, measurements and food in one place.

Glapp

Glapp's website says injections, dosage, weight, side effects, appetite and progress are free, with weekly reports, milestones and goal predictions in Glapp Max.⁴ It tracks vial and pen supply, including concentration and beyond-use date, and supports split doses and microdosing schedules. It also has an Apple Watch app, widgets, cycle tracking and "Wisdom", an AI that answers questions from clinical research. It does not describe food or protein logging. Best for: vial users who want supply tracking.

Glowise

An iPhone app (6,700 ratings, 4.8 stars) built around food: AI logging by photo, barcode, label, menu or voice, 7-day meal plans and recipes, plus dose reminders, level estimates, weight and water.⁵ The listing does not say what is free, and identifiers are listed as used to track you. Best for: people who want meal plans with their dose log.

MyFitnessPal

The big calorie counter (4.7 stars from 2.4 million ratings) now lets you log GLP-1 doses, set reminders and log how you feel to spot symptom patterns, in the US and Canada.⁶ It does not list site rotation or a level chart, the Android app contains ads, and Premium costs $19.99 a month. Best for: people who already count calories there.

Beanly (ours)

Beanly logs doses with site rotation and reminders, shows an estimated level, and is built around a daily protein target set from your goal weight, with an AI estimate of protein from a meal photo.⁷ It tracks weight, water and how you feel, shows symptom patterns around dose day, makes a one-page PDF summary for appointments, and works in 34 languages. Its App Store label lists no data used to track you. The honest weaknesses: it launched this month, so there is no rating or track record yet; there is no food database or calorie count; it does not sync with Health Connect on Android; and after 7 free days it needs Premium. Best for: people focused on keeping muscle with enough protein, and who want a lifetime option. Why protein matters: protein on a GLP-1.

How to choose

• Want it free for good? Start with the free tiers of Glapp, MeAgain or Shotsy, and check what moves behind a paywall later.
• Use vials or compounded medicine? Check supply and custom-dose support: Glapp, Pep and Shotsy describe it.
• Want to log food? MeAgain, Pep and Glowise use AI photos; MyFitnessPal has the largest database.
• Care about privacy? Compare the App Privacy section on each App Store page, especially "Data Used to Track You".

Whatever you pick, the habit matters more than the app. In the largest study so far, people on semaglutide or tirzepatide who regularly engaged and tracked their weight lost more on average, though that study can't prove the app caused it.⁸ More in what the research says about tracking apps.
