GLP-1 Food Tracker Apps: What to Track and Which App to Use

The best GLP-1 food tracker app is one that makes protein easy to see and small meals quick to log, because appetite often drops on these medications. If you also want dose reminders and side effect notes, a dedicated app like Shotsy does that; if you mainly want fast food and protein logging, a general tracker such as Lose It! or the free Calo AI covers it.

Disclosure: this page is written by the Calo AI Team, and Calo AI is our app. Competitor facts come from their own websites and App Store listings, checked on 1 October 2026.

Important: this page is about food tracking, not medication. Do not change your dose, timing or diet based on an app. Follow your prescriber, and ask them or a registered dietitian about protein and calorie targets that suit you.

What should a food tracker do on a GLP-1 medication?

GLP-1 medications such as Wegovy, Zepbound, Ozempic and Mounjaro usually reduce appetite, so many people eat much less than before. That changes what a tracker is for. Instead of policing a calorie budget, it helps you check you are still eating enough of the right things.

Look for these four things:

• Protein front and center. When portions shrink, protein is easy to miss. An app should show your protein total for the day at a glance, not bury it. Our protein on GLP-1 guide explains why it matters.
• Fast logging for small meals. Photo, voice or text logging beats searching a database for every half sandwich.
• A place to notice fluids. Some people drink less when they eat less. A water tracker, or simply a habit of checking, helps.
• Notes you can share. Weight trends and food logs are useful to bring to appointments.

If you are unsure what to eat, see what to eat on Zepbound and what to eat on Wegovy.

Which apps work as a GLP-1 food tracker?

Shotsy

Shotsy describes itself as “the all-in-one GLP-1 medication tracker for weight loss injections and pills”. Its App Store listing covers dose logging, reminders, side effects, weight, calories, protein and water, and estimated medication level charts. It says data is stored on your device and synced with iCloud. It is listed as iPhone only. Its listing also says it is “not intended to provide any medical guidance or advice”, which is the right attitude.

Lose It!

Lose It! added a “GLP-1 Support” section: log your medication and view estimated GLP-1 levels next to your food and weight. The free tier covers calorie tracking and a weight loss plan. Its App Store listing places photo meal logging, AI voice, the barcode scanner and advanced macro tracking in Premium. See our Lose It! alternative page for more.

WeightWatchers

WeightWatchers offers a GLP-1 Success Program with “specialized nutrition, dose tracking, and side-effect management”, and its Med+ plan can give access to prescriptions if eligible. Its US plans page showed $25 for the first month on a 6 or 12 month plan, then $74 or $84 a month, and says GLP-1 medication costs are not included (checked 1 October 2026). More in our WeightWatchers alternative guide.

Noom

Noom’s App Store listing mentions AI food logging and “Access to GLP-1 meds, if eligible”. It is a paid program; the US listing shows in-app purchases from $44.99 to $199.99.

Where does Calo AI fit?

Calo AI is a general calorie tracker, not a GLP-1 app, and we do not want to pretend otherwise. It has no dose log, no injection reminders and no side effect tracker.

What it does offer, free:

• AI photo meal scanning, plus voice and text logging, which suits small or irregular meals.
• A daily protein target (2.0 g per kg of body weight when losing weight) and macro analytics.
• Weight tracking, step tracking and an AI nutrition coach you can ask food questions.

The free version shows ads, including one before a meal scan, and there is a short timer between AI coach messages. Premium removes ads and waiting but adds no extra features. On iPhone, use the web app in Safari.

One caution: Calo AI sets a calorie target with a 250, 500 or 750 kcal deficit and a floor of 1,200 kcal (women) or 1,500 kcal (men). On a GLP-1 medication, your prescriber’s or dietitian’s advice comes first. If you struggle to eat even that much, tell them rather than forcing food to match an app. You can check the numbers with our protein calculator.

When is a dedicated GLP-1 app the better choice?

Choose a dedicated tracker such as Shotsy if:

• You want dose reminders and a history of injections or pills.
• You want to log side effects and see them against your dose schedule.
• You prefer data stored on your device and use an iPhone.

Choose WeightWatchers or Noom if you want coaching and clinical support in one paid program. Choose a general tracker like Calo AI or Lose It! if you mainly want quick food and protein logging. Plenty of people pair a dose app with a food app.

How do I set up a food tracker on a GLP-1 medication?

1. Ask your prescriber or dietitian for targets, especially protein, before relying on an app’s defaults.
2. Log every small meal and snack. Photo or voice logging makes this quicker.
3. Check protein in the evening, while there is still time to add a high protein snack.
4. Watch fluids, and tell your care team about side effects that affect eating or drinking.
5. Bring your logs to appointments.

If you are pregnant or breastfeeding, under 18, or have diabetes, kidney disease or a history of eating disorders, speak to your doctor or a registered dietitian before following any app’s calorie target. Results vary from person to person.
