What is an AI calorie tracker?
An AI calorie tracker is an app that uses visual cues — like food shape, color, and portion size — along with natural language input to calculate calorie intake more efficiently than traditional food logging.
Unlike traditional calorie-counting apps, which require you to manually search a food database, select portion sizes, and repeat the same grueling process for every item on your plate — every single time. AI food logging apps streamline the process.
With image recognition, voice inputs, and natural language commands, they automatically identify your meals, estimate portion sizes, and log calories for you. Beyond automation, AI meal tracking apps learn your eating habits over time. They recognize recurring meals and use predictive logging to speed up future entries — reducing friction and helping you log more consistently, especially if you find manual meal tracking tedious.
I spent several days testing dozens of popular calorie-tracking apps to compare them and pick the best of the bunch. While testing, I prioritized convenience over other factors because that’s the core appeal of AI calorie trackers. I also looked for apps that were easy to set up and use, cutting out even the most popular options if they were buggy. Based on my experience, I’ve picked out the five best AI tools for food logging in 2025.
Key benefits of using AI for diet and calorie tracking
Calorie apps with AI make food logging faster and more consistent, helping you stick to your nutrition goals with less effort. Instead of manually tallying ingredients or searching food databases, you can snap a photo or speak into your phone, and the AI will log your meal in seconds with reasonably accurate calorie estimates.
Some of these smart calorie counters also offer AI-powered diet coaching tailored to your goals — whether you’re aiming for fat loss, muscle gain, or more balanced eating.
Other benefits of AI calorie trackers include:
- Automatic syncing with AI fitness apps like Apple Health, Fitbit, and Garmin to adjust calorie targets based on your activity levels.
- Improved long-term consistency because tracking is easier and less time-consuming.
- Better accessibility for users with visual impairments or limited mobility, thanks to voice input options.
These tools aren’t just helpful for individuals. They can also support coaches and trainers working with clients to improve eating habits and build consistency over time.
A quick note on accuracy before we dive into the apps:
No calorie-tracking app — AI or not — is 100 percent precise. On top of this, AI calorie trackers are still developing and can overestimate or underestimate ingredients, especially in complex meals. Therefore, it’s always a good idea to double-check your logs to make sure the estimates are in the right ballpark.
The best AI tools for calorie tracking
1. MyFitnessPal: Best AI calorie tracker with extensive food database
Developer: MyFitnessPal, Inc
MyFitnessPal is one of the most popular calorie-counting apps, and it’s now AI-enhanced. Like other smart calorie counters, it starts by asking about your goals, lifestyle, and health, and then it creates a custom daily calorie budget to help you reach your targets.
To log your meals, MyFitnessPal offers multiple tools, including an AI meal scanner, voice logging, and barcode scanning. Just snap a photo, and the AI macro tracker will analyze your plate, identify individual items, and estimate calories and macros. You’ll also get a micronutrient breakdown to give you a better understanding of how increasing or decreasing your nutrient intake might help you reach your goals.
The app’s new voice log feature is also a useful hands-free option. Simply select “Voice Log” and speak naturally, and MyFitnessPal AI will recognize the meal and pull calorie info from its extensive database. While not always perfectly accurate, this method is great for quick logging on the go. And if the entry looks off, you can delete it and try again.
One thing that stood out to me while testing MyFitnessPal was its massive food database — over 18 million meals globally. It even recognized one of my local meals, jollof rice, which many apps didn’t have. While that’s impressive, please note that some entries are user-submitted and may therefore be inaccurate. To ensure you use correct entries when logging meals, stick with verified food info marked by a green check. MyFitnessPal also includes barcode scanning for packaged foods and offers custom meal and workout plans.
For personal trainers and health coaches, MyFitnessPal can be a helpful client accountability tool. Clients can make their food diaries public or share them directly with other users, allowing coaches to review logs and provide feedback.
In addition to meal tracking, MyFitnessPal allows you to track your sleep, steps, weight, and workouts from its comprehensive dashboard. It also integrates with a range of fitness and wellness apps, and everyone, including professionals, can use third-party tools to sync and monitor health data more holistically.

2. MyNetDiary: Best AI calorie counter with verified food logs
Developer: MyNetDiary, Inc
MyNetDiary is the AI nutrition planner for everyone who cares about accuracy in food tracking. Unlike many meal trackers that rely on crowdsourced entries, MyNetDiary boasts a clean, verified food database with nearly 2 million items to ensure all food entries are accurate and trustworthy.
You can choose a diet or style that works for you — like calorie counting, keto, or vegan — and the app will suggest a calorie target based on your goals. When it’s time to log meals, it provides an AI food recognition scanner for snapping a photo of your plate. From each photograph, MyNetDiary will identify food items and calculate their total calories. When I tested the AI meal scan on a simple dinner, the calorie estimate was within the standard range found on Google. The app also broke down the macro and micronutrients. If you’re on the Premium plan, you can set custom macro targets and get more advanced nutrient insights. Apart from the AI meal scanner, MyNetDiary stands out for its free barcode scanner for logging packaged foods in seconds. It can also suggest meal plans and recipes based on your targets, and you can import recipes from websites to calculate their nutritional info.
As you track your meals, you’ll see your progress visualized through the app’s apple-shaped calorie meter and weight graph. You can upload progress photos, join the MyNetDiary community for support, and sync your fitness data with wearables like Apple Watch and Fitbit.

3. SnapCalorie: Best for quick AI food logging
Developer: Perception Labs, Inc
SnapCalorie is a newer calorie app with AI launched in 2023 that focuses on fast, photo-based logging. Like other AI meal trackers, it starts with a quick intake survey to assess your goals and health profile before recommending a daily calorie target based on guidelines such as those from the Dietary Guidelines for Americans.
The app’s AI meal scanner is especially handy when eating out. Just take a photo of your plate and then focus on your meal. You can use the “Add Note” feature to include extra context — like a menu description or any hidden ingredients — to help the AI make more accurate estimates. After analyzing the photo, SnapCalorie first estimates the portion size (which its founders say helps reduce errors), then identifies food items, calculates calories, and assigns the meal a food score. This food score is based on the meal’s calorie count, nutritional value, and macronutrient composition. If the AI gets it wrong, you can edit the food item or search for a better match in its database.
SnapCalorie also includes a voice note feature for hands-free food logging. For instance, if you’re using a kitchen scale to weigh your meals, just read the values aloud, and the AI macro tracker will log them. Forget to log multiple meals during the day? Describe them to the app, and SnapCalorie will use average portion sizes from its database to estimate and log them. Whether or not its estimates are accurate is another topic for discussion, but the real benefit here is consistency. These tools are especially helpful for beginners looking to build a sustainable food tracking habit. As you continue to log your meals, SnapCalorie learns from your behavior and improves its estimates.
The app features a barcode scanner and an AI chatbot for asking questions whenever you disagree with its calculations, and the Apple Health integration can track your activities. Unlike other calorie-tracking apps that lock meal scanning behind a paywall, SnapCalorie offers it for free — but limits you to three photo scans per day.
Pros:
- Easy to use and great for consistent logging
- AI meal scan is available on the free plan
Cons:
- May not identify every ingredient
- Limited integrations (only Apple Health for now)
Key features:
- Fast AI meal scan
- Voice note feature for hands-free logging
- AI food scoring and chatbot support
Limitations:
- Smaller food database, so barcode scanning may not pick up some items
Plans/Pricing:
- Free: includes three AI scans per day.
- Premium: €89.99 per year for unlimited AI meal scans. A seven-day trial is available.

Weight Watchers is a long-established nutrition and weight loss program that combines structured food tracking with behavior change support. It offers a sustainable way to lose weight using its signature points-based system that allows you to eat healthy meals within a personalized daily budget.
