The Best Free Calorie Counter App for People on Mounjaro or Wegovy

Most general calorie counter apps were designed before GLP-1 medicines existed. They assume a normal appetite, regular portion sizes, and consistent hunger cues. On Mounjaro or Wegovy, the reality is often very different: reduced food noise means some people forget to eat enough protein; slower gastric emptying means heavy meals sit uncomfortably; and low calorie intake needs to be paired with high nutritional quality to avoid muscle loss.

A calorie counter that genuinely works for GLP-1 life should do more than add up numbers. Here is what actually matters:

• Protein tracking — hitting a protein target matters more than ever when eating less overall. Look for an app that surfaces protein alongside calories.
• Speed and ease — when appetite is low and meals are small, you need logging to take seconds, not minutes. Photo scanning and barcode scanning cut friction dramatically.
• Macro and fibre visibility — calories alone miss the picture; fibre supports digestion, which is especially relevant when GI side effects are a factor.
• Integration with the rest of your journey — a calorie counter that also logs your dose, weight, and side effects gives you context that a standalone food app never can.

If you are weighing up the options, our guide to the best free calorie counter apps covers the landscape in more depth, and our calorie counter app overview explains how food tracking fits into a broader GLP-1 tracking routine. For iPhone users specifically, there is also a dedicated look at the best free calorie counter app for iPhone.

One practical note: general educational guidance suggests that most adults aiming for gradual weight loss stay somewhere in the range of 1,200–1,800 kcal per day depending on size, activity, and individual factors — but what is right for you is a conversation to have with your prescriber or doctor, not a number to set based on an app alone.

GLP Trackr's standout food-logging feature is its AI photo scan: point your camera at your plate and the app instantly estimates calories, protein, carbohydrates, fat, and fibre — no manual searching required. This matters most on days when appetite is low and meals are small, because the last thing you want is to spend three minutes searching a database for half a portion of something you barely ate.

Beyond photo scanning, you can also log food by barcode or manual search, set daily targets for calories, protein, water, and fibre, and track progress against those targets in a single morning check-in. The app is available free on the App Store and Google Play, with a 7-day free trial — no subscription is needed to try it.

Because GLP Trackr is built specifically for Mounjaro and Wegovy users, your food data sits alongside your dose log, weight chart, and side-effect tracker. That means you can start to see patterns — whether a higher-protein day correlates with better energy, for instance, or whether certain foods appear on the same days as digestive discomfort. These are the kinds of observations worth bringing to your next prescriber appointment.

You might also find it useful to explore whether there is truly a free calorie counter app that covers everything, or browse more free calorie counter options to compare features.

GLP Trackr is a tracking and journaling tool — it is not a substitute for guidance from your prescriber or doctor. If you have questions about your calorie needs, nutritional targets, or how your diet interacts with your medication, always bring those to your healthcare professional.
