Best GLP-1 Tracker Apps in 2026: An Honest Comparison

The short version

If you are on a GLP-1 and looking for something better than the notes app, the honest answer in 2026 is that the category has matured and several of these are genuinely good. What separates them is no longer whether they can record a shot — they all can — but what they do with it afterwards, what they charge, and where the data lives.

App	Best at	Cost model	Storage
Shotsy	Dose charts and estimated medication levels	Free core, paid extras	Cloud
Glapp	Shot-cycle insight, supply tracking	Generous free tier	Cloud
MounjaGO	One-time purchase, English/French, medical PDF	~$12 lifetime	Local
GlucoPal	Free side-effect tracking	Free core, paid AI food	Cloud
Pep	Simple reminders and routine	Subscription	Cloud
MeAgain	All-in-one breadth, AI companion	Free core, ~$10/mo premium	Cloud
Regimen	Doses tied to labs and health metrics	Free + paid	Cloud
MyFitnessPal	Food database and barcode scanning	Free + premium	Cloud

Treat the table as a starting point for your own look rather than the final word. Pricing and feature sets in this category move quickly, and the only version that matters is the one on the store page the day you download it.

What a GLP-1 tracker actually has to do

General weight-loss and calorie apps were not designed around a weekly injection. They will happily record your weight, and that is roughly where their usefulness ends for this.

GLP-1 treatment has a specific shape. There is a weekly dose. There is a titration schedule that steps up over months. There are side effects clustered around injection days. There are injection sites that need rotating. And there are appointments where all of it has to be summarised quickly, usually in less time than you expected to have.

A tracker built for this handles that shape. One that is not built for it leaves you keeping the important parts somewhere else — which is how people end up with an app, a notes file and a photo of a handwritten schedule, none of which agree with each other.

Five things are worth checking before you commit months of history to any of them.

1. Dose logging that matches your actual schedule

The baseline is recording what you took and when. The differentiator is what happens when reality does not cooperate.

You will at some point take a shot a day late. You will skip one. Your provider may hold you at a dose for an extra month, or step you back down. Some apps handle that gracefully and some fight you, because they were built assuming a clean seven-day cadence that nobody sustains for a year.

If you already know your schedule is not a textbook one, test that specific thing first. Log a late dose and see what the app does with it.

2. Side effects recorded against the cycle

Recording that you felt sick is nearly useless on its own. Recording that you felt sick on day two after a shot, at the dose you had just moved up to, is the thing that turns into an answer.

The apps that do this well tie a symptom entry to where you are in the shot cycle automatically, so the pattern assembles itself. The ones that do not leave you with a symptom diary you have to cross-reference against a dose diary by hand — which is exactly the work you downloaded an app to avoid. There is more detail on what to record in the guide on tracking GLP-1 side effects.

3. Injection site rotation

This is small and it matters more than it sounds. Rotating sites is standard practice, and remembering where you injected eight days ago is genuinely hard.

Some apps offer a body map you tap. Others give you a text list. Either works, but the ones that show you what you used recently — rather than making you scroll back through history to work it out — are the ones you will actually keep using. The injection site rotation guide covers the underlying practice.

4. Export

Export is the feature nobody evaluates and everybody eventually wants. It matters for two reasons.

The first is your appointment. A summary your provider can read in thirty seconds is worth more than twelve weeks of raw entries, and PDF export is how most people produce one. The second reason is leverage: an app you can leave is an app that has to keep earning your subscription. If there is no export, your history is a hostage.

5. Where the data goes

This is health data about a prescription medication. It deserves a moment's thought.

Most of the popular trackers sync to their own cloud, which is what makes the data available across your phone and tablet. That is a reasonable trade and plenty of people will accept it. But the trade should be a decision rather than something you discover later, so read what the app says about storage and sharing before you start, not after you have six months in it.

The apps people actually use

Shotsy

The most established dedicated GLP-1 tracker, and the one most others are compared against. It covers shot history, dose tracking, injection site rotation with a body map, side effect logging, weight, reminders and PDF export, and its estimated-medication-level charts are the most developed in the category.

Core tracking is free, which was not always the case and is worth knowing if you formed an opinion about it a year ago. It has a large user base and a long track record, which counts for something when you are trusting an app with a year of medical history.

If you want a thorough, proven place to record everything and you are comfortable doing the interpretation yourself, this is the default recommendation. Our full comparison with Shotsy goes into where we think a different approach helps.

Glapp

Strong on the shot cycle specifically. There is a full comparison with Glapp if it is on your shortlist. Its shot-phase view frames the week in terms of where you are relative to your last injection, which is the frame most people are implicitly using anyway. It also tracks supply, which matters more than you would expect once you are managing refills against a titration schedule.

The free tier is generous by category standards. The common criticism is breadth — there are a lot of metrics on offer, and if you only want dose and symptoms it can feel like more app than you asked for.

MounjaGO

The one to look at if subscriptions are the objection. It is a one-time purchase, around $12, rather than a recurring fee, and it advertises local storage rather than cloud sync — the only well-known option in this category that makes that its position. It ships in English and French and produces a medical PDF report.

The trade for the price and the privacy is polish and predictive charting. It is a utility rather than a showpiece — the full MounjaGO comparison goes into what that costs you.

GlucoPal

Notable for having the strongest free side-effect tracking in the category. If symptom logging is the specific thing you want and you do not want to pay for it, start here. Food logging beyond the basics moves behind a paid tier, as it does nearly everywhere.

Pep

The simpler end. Reminders, a routine dashboard, straightforward shot logging, and AI photo food recognition on the paid tier. It covers oral GLP-1s as well as injectables, which not every tracker does.

It has less medication-level depth than the all-in-one trackers. Whether that is a limitation or the entire appeal depends on what you want. Some people want the graph. Some people want a button and a reminder.

MeAgain

The broadest all-in-one feature set — shots or pills, food, side effects, weight, progress and an AI companion in one place.

It carries a 4.8 rating from roughly 25,000 App Store ratings, so plenty of people are getting on with it.

The free tier covers more than people expect: shots, side effects across 18 common symptoms plus custom ones, food logging, protein and water targets and a weight trend. Premium, around $10 a month, adds photo food logging, Journey Cards, the widget and unlimited AI chat — the full MeAgain comparison covers the trade.

Regimen

The one to look at if you are months rather than weeks into treatment and your bloodwork matters to you. Regimen ties each dose to estimated medication levels, lab results and other health metrics in a single view, which is the comparison most trackers cannot make because the labs live in a patient portal somewhere else. It carries a 4.8 App Store rating.

The trade is a steeper learning curve. In month one it is more instrument than most people need; by month nine it is doing something nothing else here does. The full Regimen comparison has the detail.

Cronometer and the generalist food trackers

Worth a mention because they keep coming up: Cronometer remains one of the strongest generalist food databases and has added GLP-1 features. Like MyFitnessPal it is a nutrition tool first, with no model of a weekly injection — the same division of labour applies.

MyFitnessPal and the general calorie apps

MyFitnessPal has the food database no dedicated GLP-1 app is going to match, and barcode scanning that has had fifteen years of work behind it. It also has no concept of a weekly injection.

This is why running both is so common, and it is a perfectly sensible answer rather than a failure to choose. Our full write-up on MyFitnessPal for GLP-1 covers the division of labour. If protein is your specific concern, the article on protein targets on GLP-1 is more directly useful than any app comparison.

Which one is right for you

If you want the most established option and the best dose charting: start with Shotsy.

If subscriptions are the dealbreaker: MounjaGO's one-time purchase is the clearest answer in the category, and it is the one app here that stores data locally rather than in a cloud.

If you want the shot cycle front and centre: Glapp.

If you track lab results: Regimen.

If you want everything in one app and will pay up front: MeAgain.

If you only want free side-effect tracking: GlucoPal.

If you want simple: Pep, or honestly a notebook. Paper is a serious option and we make the case for it rather than pretending otherwise.

If you want to build something exactly yours: a spreadsheet will beat every app here on flexibility and lose to all of them on the odds you keep it up. That trade is covered in spreadsheet versus a dedicated tracker.

Where Gleva fits, and the disclaimer

Gleva is in development and has not launched. We are building it around correlation — the questions that are relational rather than historical. Does the nausea track my dose increases or my meals? Is this a plateau or a normal flat fortnight?

That is a narrower claim than most of the apps above make, and a narrower product. We are not going to tell you it is better than an app that has shipped and helped a lot of people while ours is still being built. If you are starting treatment this month, download one of the above.

We will say so on this page when there is something to judge.

What we are not comparing on

We have deliberately left out star ratings and download counts. Both are real signals about an app's popularity and neither tells you whether it fits your treatment, which is the only question that matters here.

We have also left out any claim about which app helps you lose more weight. No tracker does that. They record what happens; your medication and your provider are what change it.

Every app named here is a trademark of its respective owner. Gleva is not affiliated with, endorsed by or sponsored by any of them, and nothing on this page is medical advice — talk to your provider about your treatment.
