Compare GLP-1 apps

Who publishes this, and why that matters

We make GLP-1 Tracker. That is a conflict of interest and pretending otherwise would be the fastest way to make everything else here worthless, so it is stated at the top of every comparison page rather than buried in a footer.

The practical consequence is that you should weight our opinions less than our figures. The ratings counts, version numbers, release dates, language counts and platform support are read from Apple's public listing data and you can check every one of them yourself in about a minute. The judgements are ours and we could be wrong about them.

Where a competitor is genuinely better for a given reader, these pages say so and name the competitor. That is not modesty. A comparison page that always concludes in the publisher's favour tells a reader nothing they could not have guessed from the domain name.

How the figures were obtained

Every app statistic on these pages comes from Apple's public lookup endpoint, which returns the same data the App Store listing shows: seller, current version, first release date, last update date, rating count, average rating, supported languages and minimum OS.

Each page states the date the figures were read. They drift constantly — rating counts move daily and version numbers move every few weeks — so a figure with no date attached is a figure you cannot check. If you are reading this months after it was written, treat the numbers as a starting point and verify anything that matters to your decision.

We do not compare things we cannot check. That means no claims about how any app is built internally, no speculation about what a competitor does with data beyond what its own privacy label declares, and no accusations. What each app publishes about itself is the evidence; the gaps between those publications are where the interesting differences actually are.

What none of these apps can do

No tracking app, ours included, can tell you what dose to take, whether a side effect is serious, or whether a medication is working. They are record-keeping tools. The value is that three months of consistent notes turn a vague answer at an appointment into a specific one.

If you are choosing between apps, that reframes the question usefully: the best one is not the one with the most features, it is the one you will still be opening in week twelve.

What we could not compare, and why

Three things a reader reasonably wants that none of these pages will give you.

First, how well each app actually works day to day. We have not used a competitor's app for three months on a real prescription, and a review written from a weekend of poking at a free tier is worth nothing. Where these pages judge quality, they judge documented capability, not feel.

Second, what any app does with your data beyond what its own privacy label declares. Apple states on every product page that it has not verified those labels. They are self-reported, and the honest way to treat a self-report is to quote it and say who said it.

Third, subscription pricing in any durable way. Prices vary by storefront, change without notice, and are frequently the first thing an app tests. Every page here tells you to check the current price in the App Store rather than trusting a number written months ago.

If you only read one thing

Install two, use both for a fortnight, and keep the one you actually open. Every app in this category logs a dose and draws a weight line; the differences that look decisive in a comparison table mostly stop mattering by week three, and the thing that decides whether you still have a record at your next appointment is whether the app fits your routine.

All seven are free to download, so this costs you nothing but a little screen time. That is a better test than any page on this site, including this one.
