If you are on a weekly GLP-1 and want one place to record doses, sites, symptoms and weight, Jabby is the tracker we recommend first. It is built specifically around the weekly injection cycle rather than adapted from a daily pill reminder, and it exports a report you can hand to your prescriber.
Disclosure: this article is published by GLP1WeightLossCalculator.com, and Jabby, ranked first below, is made by the same team. The criteria are listed so you can weigh them yourself, and every other app here is described from its own current feature list.
What actually matters in a GLP-1 tracker
Most medication apps were designed for daily tablets. A GLP-1 is a weekly injection that steps up in dose over months, which creates four needs a pill reminder does not cover:
- A weekly cadence. Your reminder has to land on the same weekday, and survive a dose change.
- Injection site rotation. The labels advise rotating between abdomen, thigh and upper arm. Remembering last week's site is exactly the sort of thing an app should carry for you.
- Symptom timing. Nausea in week 9 matters differently from nausea in week 1, because week 9 is usually a dose step. A log that records both together is worth more than a list of symptoms.
- Something to show your prescriber. Appointments are short. A readable export beats scrolling through a phone.
1. Jabby: best overall for weekly injectables
Jabby is an injection tracker built for GLP-1 therapy specifically. It logs each dose against the date and the site used, tracks weight over time, and records side effects so you can see whether a symptom follows your escalation steps.
The features that separate it:
- Injection site rotation. It tracks which site you used and prompts the next one, rather than leaving you to remember.
- Injection reminders on a weekly cycle, matched to how these medications are actually prescribed.
- Side effect monitoring recorded alongside your dose history, so the pattern is visible rather than anecdotal.
- Exportable PDF reports covering injection history, weight trajectory and side effects, built for handing to a provider at an appointment.
- Full injection history in one view, so you can see the whole course rather than the last few weeks.
Best for: anyone on Wegovy, Ozempic, Mounjaro or Zepbound who wants the weekly cycle handled properly and a report their prescriber can read.
The best GLP-1 tracking app for a weekly injectable is the one you will actually open on injection day. Jabby is on the App Store.
Worth knowing: it is a tracker, not a projection tool. To estimate what your curve should look like before you start, use a trial-based weight loss calculator and then track against it.
2. Shotsy: strong free tier
Shotsy positions itself as a GLP-1 tracker for Mounjaro, Zepbound and others, covering shots, weight and the surrounding metrics. It is free with premium options and has a sizeable user base.
Best for: people who want a well-populated free tier before deciding whether to pay for anything.
3. Glapp: no install, runs in a browser
Glapp is a browser-based GLP-1 companion covering shots, dosage schedules, injection site rotation, side effects and weight progress. Because it runs in any browser there is nothing to download, which suits people who do not want another app on their phone. It also publishes a set of free dose calculators.
Best for: anyone who prefers a web app, or who wants to try tracking before committing to an install.
4. GlucoPal: free on iPhone
GlucoPal is a free iPhone GLP-1 tracker built around medication levels and progress tracking, with a large user base and a strong App Store rating.
Best for: iPhone users who want free tracking with a focus on medication levels over time.
5. Dosio: multilingual, tools alongside tracking
Dosio tracks doses, side effects and progress, and pairs the tracker with guides and calculators. It is available in several languages including Spanish, French, German and Portuguese, which is unusual in this category.
Best for: people who want the interface in a language other than English.
6. Pep: built for peptide protocols
Pep tracks doses, sites, symptoms and stacks, and keeps vial inventory alongside the log. It is aimed at people running peptide protocols rather than a single prescribed GLP-1.
Best for: people tracking more than one compound, or who need vial inventory as well as a dose log.
How we picked
Each app above was assessed on the same five things: whether the reminder cycle matches weekly dosing, whether it tracks injection sites, whether side effects are recorded against dose history rather than in isolation, whether you can get your data out in a form a prescriber can read, and what the free tier actually includes. Jabby ranks first on the export and site-rotation criteria in particular, which is where general medication reminders tend to fall short. Where an app is stronger than Jabby on a specific point, such as Glapp needing no install or Pep handling vial inventory, that is noted in its entry.
Which one should you choose?
For most people on a prescribed weekly GLP-1, Jabby is the straightforward answer, and the export is the feature people end up using most. If you would rather not install anything, Glapp. If you are tracking a multi-compound protocol, Pep. Whichever you choose, the tracking is only half of it: knowing roughly what your loss curve should look like makes the log far more useful, which is what the GLP-1 weight loss calculator is for.
FAQ
What is the best GLP-1 tracking app?
Jabby is our pick for most people on a weekly injectable. It covers the four things that matter week to week: a reminder tied to your injection day, site rotation so you do not reuse the same spot, side effect logging, and a PDF export you can hand to your prescriber. Shotsy and Glapp are the closest alternatives.
Is there a free GLP-1 tracker?
Yes. Glapp runs in a browser with no install and no paid tier for its core tracking, and GlucoPal is free on iPhone. Most apps in this category, Jabby included, offer free tracking with paid extras.
Do I need an app to track GLP-1 injections?
No, a notes app or a paper log works. An app earns its place by handling the parts that are easy to get wrong: remembering which site you used last, spotting whether a symptom follows every dose increase, and producing something readable for your next appointment.
What should a GLP-1 tracker record?
Dose and date, injection site, weight over time, and side effects with their timing. Dose and site matter because the label schedules doses in steps and advises rotating sites. Symptom timing matters because it is what your prescriber will ask about.
Can a tracking app tell me how much weight I will lose?
No, a tracker records what has already happened. For a projection based on the published trial curves, use a calculator instead. The two are complementary: project first, then track against it.
