Most people on a GLP-1 medication are recording their progress in a notes app, a spreadsheet, or nowhere at all. Then a clinician asks when the dose went up, or what the side effects were like in month two, and the answer is a guess. The software market has finally caught up: 2026 has more apps built specifically for semaglutide and tirzepatide users than any previous year, plus a wave of established nutrition trackers that added medication logging in the last twelve months.
This comparison looks at ten products people actually use to keep track of a GLP-1 course, what each one verifiably does, and where each one stops. Prices and features were checked against official product pages and store listings on 18 August 2026. Where a company does not publish something clearly, this article says so rather than guessing.
Quick answer: which GLP-1 tracker suits which person
There is no single best app, because people on these medications are solving different problems. Broadly:
- Best for connecting medication to the rest of your health data: BodySynk, dose history, weight, blood tests, nutrition, activity and wearables in one record.
- Best dedicated GLP-1 companion: Shotsy, purpose-built dose logging, injection-site rotation, reminders and side-effect notes.
- Best free medication logging inside an app you already use: MyFitnessPal, which added a free GLP-1 Support module in April 2026.
- Best for nutrient depth while you are eating far less: Cronometer, for micronutrients, and Carb Manager if you also track glucose or ketones.
- Best if you want the prescription and the app from the same company: WeightWatchers Clinic, Noom Med or Found.
- Best for pairing medication with glucose data: Levels.
- Best simple calorie and protein log: Lose It!
For the wider picture of what to record week by week, see our guide on tracking GLP-1 progress. If you only want to know when your next dose is due, a dedicated tracker is enough. If you want to understand what twelve months of treatment did to your bloodwork, body composition and sleep, you need something wider.
What a GLP-1 tracking app should actually track
The useful categories are not mysterious, but very few apps cover all of them.
Medication and dose. Which drug, which strength, which day. Titration means the dose changes every few weeks, and a year later almost nobody remembers the exact sequence. Dose history is the single most valuable thing to record, because it is the variable your clinician will ask about first.
Injection schedule and site. For weekly injectables, a rotation record reduces the chance of repeatedly using the same spot. Anyone using the oral option approved in 2026 has no site to rotate, which is one reason tracker feature sets are diverging.
Weight, and the shape of the trend. Daily weight is noisy. A weekly average, or a trend line across months, tells you far more than any single morning reading.
Measurements and photos. Waist circumference often keeps moving after the scale stalls, which is worth knowing during a weight-loss plateau.
Protein, fibre and hydration. Appetite suppression makes it easy to undereat protein badly. Our guide to eating well on these medications covers why protein and fluid intake deserve attention while total intake falls.
Activity, especially resistance training. Rapid weight loss includes lean tissue as well as fat. In the STEP 1 body-composition analysis published in the New England Journal of Medicine in 2021, a substantial share of the weight lost on semaglutide was lean mass, one of the reasons strength work and protein come up so often in clinical guidance.
Sleep and recovery. Nausea, fatigue and disrupted sleep are commonly reported early in treatment. Wearable data gives you a record of whether that settled.
Symptoms and side effects. Gastrointestinal effects are the most frequently reported, and both the NHS guidance on semaglutide and the FDA's semaglutide safety information describe what warrants medical attention. A dated log makes the difference between "I felt rough for a while" and "this started three days after the 1.0 mg step-up".
Blood tests. HbA1c, lipids, liver and kidney markers, ferritin and vitamin B12 all move for some people during significant weight change. Our explainers on HbA1c and cholesterol results go through what these numbers mean.
The ten apps
1. BodySynk
BodySynk is a whole-health record rather than an injection reminder. Its obesity-drugs section holds your medication, your dose history with dates, your starting and target weight, weeks on treatment and a weight trend chart. That sits inside the same account as your blood test results, medications, meals, activity, wearable data and symptom notes, all of which land on one timeline. You can ask questions about your own record, and generate a summary document to take to an appointment.
Strengths: dose history and weight sit next to bloodwork, nutrition, sleep and symptoms, so a twelve-month view is possible rather than a set of disconnected logs. Blood test uploads are parsed into trends, which is unusual in this category.
Limitations: BodySynk does not send injection reminders and has no injection-site rotation map. It is not a prescriber and does not sell medication. Someone who wants a weekly push notification and nothing else will find a dedicated tracker simpler.
Best for: people who want their medication understood in the context of everything else, particularly anyone with bloodwork to keep an eye on.
2. Shotsy
Shotsy is the best-known standalone GLP-1 companion app and is not tied to any clinic. It logs doses and pills, schedules and reminders, injection-site rotation, side effects, weight, calories, protein and water, imports weight and nutrition figures from Apple Health, and produces a PDF for appointments. It also draws an estimated medication-level curve from published half-life data, which the company is careful to describe as an estimate rather than a measurement.
Strengths: the most complete injection-specific feature set reviewed here, free to start, and it supports branded and generic products including the oral option.
Limitations: the App Store listing requires a recent iOS version, Android feature parity is not documented, and the price of the paid tier is not published outside the app. It holds no lab or medical-record data.
Best for: anyone whose main need is reliable dose, site and side-effect logging.
3. MyFitnessPal (GLP-1 Support)
In April 2026 MyFitnessPal added a free GLP-1 Support module that logs medication, dose, timing and injection location alongside food, with reminders and side-effect tracking. For the millions of people already logging meals there, this removes the need for a second app.
Strengths: the food database is the largest in the category, and the medication feature costs nothing on top.
Limitations: it is new, so there is little track record, and the depth of dose scheduling has not been documented to the level a dedicated tracker offers. No lab or clinical record storage.
Best for: existing MyFitnessPal users who want basic medication logging without switching.
4. WeightWatchers Clinic
WeightWatchers folded its Sequence acquisition into WW Clinic and the in-app GLP-1 Success programme. Its own materials describe logging medication, dose and injection site, side effects, weight, activity and nutrition with a focus on protein and fibre, alongside telehealth prescribing.
Strengths: prescribing and tracking come from the same organisation, and WeightWatchers publishes outcome research tied to the programme.
Limitations: the tracking sits behind a paid clinical membership whose full price is not itemised on the public pages, and availability varies by country.
Best for: people who want one company handling both the prescription and the day-to-day support.
5. Noom Med
Noom Med layers prescribing onto Noom's behaviour-change app, so the food logging, weight tracking and psychology-led lessons carry over. Noom publishes starting prices on its own site: a microdose programme advertised from $49 to start and $179 a month afterwards billed quarterly, with other tiers listed from $129 and $149.
Strengths: among the more transparent programmes on price, and the coaching content is genuinely distinctive.
Limitations: published figures are promotional starting prices with conditions attached. No injection-site rotation feature was found in its materials, and there is no lab record.
Best for: people who want the psychological side of eating addressed alongside the medication.
6. Found
Found is a US telehealth weight-care service that leads with insurance coverage rather than cash pay, and prescribes products including Wegovy and Zepbound. Its own site advertises membership discounts rather than a fixed price, and it does not itemise its in-app tracking features publicly, so this comparison does not claim a feature list for it.
Strengths: an insurance-first route to treatment, which matters in the US where coverage decides affordability.
Limitations: the least transparent of the products reviewed on both price and app features. Prospective users should check what the app records before signing up.
Best for: US patients whose priority is getting covered access rather than detailed self-tracking.
7. Levels
Levels began as a continuous glucose monitoring app and now runs a GLP-1 track pairing prescribed medication with CGM data, lab testing and coaching aimed at retaining muscle during weight loss.
Strengths: glucose data alongside medication is a genuinely different angle, and the muscle-retention focus addresses a real clinical concern.
Limitations: the signature feature needs a CGM sensor, the app is iPhone-only per its store listing, the programme price is not published, and it is not built as an injection log.
Best for: people who want to see how their glucose responds while on treatment.
8. Cronometer
Cronometer is the most nutritionally detailed tracker here, covering micronutrients that most calorie apps ignore. It publishes guidance for GLP-1 users, but it has no native medication tracker, a request for one is still open on the company's own user forum, and people currently log doses as custom entries.
Strengths: unmatched micronutrient detail, which matters when total food intake drops sharply for months.
Limitations: no dose, site or reminder features at all.
Best for: anyone worried about nutrient intake while eating much less. Pair it with something that handles the medication side.
9. Carb Manager
Carb Manager is a low-carb and keto tracker whose paid tier adds blood glucose, ketone and insulin logging, plus connections to Fitbit, Garmin and Apple Health.
Strengths: strong metabolic logging for people who also manage type 2 diabetes, and broad device support.
Limitations: nothing GLP-1 specific. No dose log, no site rotation, no medication reminders.
Best for: low-carb eaters tracking glucose who will log medication elsewhere.
10. Lose It!
Lose It! is a long-running calorie and macro tracker. It publishes clinician-written guidance on what to track during GLP-1 treatment, but the advice is about using existing features rather than a dedicated module.
Strengths: simple, mature, and easy to sustain over months.
Limitations: no native dose tracking; medication has to be logged manually as a note or custom entry.
Best for: people who want an uncomplicated food and weight log.
Why weight alone misses part of the story
The scale answers one question. It cannot tell you whether the weight came off proportionally, whether your lipids improved, whether your HbA1c moved, whether your ferritin drifted down as you ate less, or whether the fatigue you felt in month three lined up with a dose increase.
Two findings make the case for a wider record. In the STEP 1 trial extension published in Diabetes, Obesity and Metabolism in 2022, participants regained a substantial part of the weight they had lost in the year after stopping semaglutide, and cardiometabolic markers moved back towards baseline with it, the numbers underneath the weight matter, not just the weight. And in SURMOUNT-1, published in the New England Journal of Medicine in 2022, tirzepatide produced average reductions of roughly a fifth of body weight, a scale of change that touches blood pressure, lipids, glucose regulation and body composition at once.
None of this means an app can interpret your health for you. It means that a year of treatment produces a lot of information, and the pieces are more useful together than apart. If you are stopping or pausing treatment, our guide on coming off these medications covers what tends to happen next.
Dedicated GLP-1 tracker or whole-health platform?
Both are defensible choices, and the honest answer depends on what you want from the software.
A dedicated tracker is the better choice if your priority is the medication itself: never missing a weekly dose, rotating injection sites properly, having reminders that actually fire, logging nausea day by day, and showing a clean dose history at your next appointment. Shotsy does this better than any general platform, including BodySynk, and the newer entrants in that niche are converging on the same feature set.
A whole-health platform is the better choice if your question is broader: what has happened to my health over the last year, not just my weight. That means bloodwork trends, medication alongside supplements, nutrition, training, sleep and symptoms in one place, and a record that keeps working after you stop the medication. This is where BodySynk is designed to be useful, the medication is one stream among several rather than the whole product.
Plenty of people run both, using a dedicated app for the weekly rhythm and a wider record for the longer view. There is no prize for consolidating everything into one icon.
How to choose
Work through this list before installing anything:
- Name the thing you actually want to know. "Did I take it?" and "what changed in my health this year?" lead to different apps.
- Check the specific features, not the marketing. Dose logging, site rotation and reminders are three separate things, and plenty of apps have only one.
- Look at whether it holds clinical data. If you have blood tests, only a few products in this category store and trend them.
- Check the export. You want a document you can take to a clinician, and your data out if you leave.
- Read the privacy terms. This is medication and body-weight data. Find out who processes it and where.
- Confirm the price before subscribing. Several products in this comparison do not publish their subscription cost outside the app or a sales call.
- Decide whether you want the prescription bundled. Programme apps tie your data to your treatment provider; standalone apps do not.
- Ask whether it survives the medication. If you stop treatment, does the record still make sense?
Where this leaves you
The GLP-1 tracking market in 2026 splits into four groups: dedicated companion apps built around the injection, telehealth programmes where the app comes with the prescription, nutrition trackers retrofitting medication logging, and whole-health platforms that treat the medication as one signal among many. Each solves a real problem, and the one that suits you depends on the question you are trying to answer.
What most people underestimate at the start is how much information a year of treatment generates, and how little of it survives in a notes app. Dose changes, weight trends, side effects, blood tests, sleep and training all belong to the same period of your life, and they are considerably more informative read together.
Your medication is one part of your wider health record: dose history, weight, bloodwork, nutrition, activity and wearables read best together, alongside a summary you can take to your next appointment.
Speak to your prescriber or another qualified healthcare professional about anything to do with your dose, your side effects or whether to continue treatment. If a symptom is severe or persistent, contact them rather than waiting for your next scheduled visit.
