Which Keto Tracker App is Right for You?

Updated October 2026: we checked which 2019 apps still exist, updated features and pricing models, flagged an app that is no longer updated, added Cronometer and rewrote the Heads Up section for practitioners.

The ketogenic diet has gone mainstream, and with it, so have the number of apps available to efficiently track your progress. But finding the right keto tracker app can get complicated and confusing quickly. There are big differences between free tracking apps with basic functionality and premium apps offering a broader range of keto diet tracking plus other useful features that help you more easily monitor and manage your overall health, no matter what your goals.

So here are some useful tips to help determine if a free keto tracker app is right for you (or the clients you coach through a ketogenic therapy program), or if you may want a little more "spice" in your "keto app sauce."

A note on this update: this comparison was first published in 2019. In October 2026 we re-checked each app against its current App Store, Google Play and company listings. Features and pricing change often, so confirm current details in the store before recommending an app to clients. The pros and cons below reflect our original review plus what has changed since.

The Freebie Options

MyFitnessPal

MyFitnessPal is a popular calorie counter web and mobile app for tracking fitness and food intake. Its food diary couples with the calorie counter to help track every calorie, nutrient and vitamin you consume. The macros view helps you analyze eating patterns to determine where you may be out of balance so you can make necessary adjustments to stay on track with your goals.

• The Pros: MyFitnessPal is convenient to use with easy access to a huge database of foods and information. It also integrates with Heads Up as well as a host of other activity, fitness and lifestyle apps and wearables (see all integrations).
• The Cons: The food database has many listings that are not verified, which can make it hard to find the right food. There is also more emphasis on calories versus macros, which can make it less keto-friendly than dedicated keto tracker apps. Since 2022, the barcode scanner has been a Premium-only feature, and custom macro goals are listed as a Premium feature, which narrows what the free version offers keto dieters. It may be best suited for those who are steadfast in their dedication to calorie counting as the best method to reach their goals.
• Cost: Free version with ads; paid Premium and Premium+ tiers (Premium includes barcode and meal scan, custom macro goals and an intermittent fasting tracker)
• Platforms: Web app and mobile app on Apple & Android

Carb Manager

The Carb Manager Low-Carb Diet Tracker is a great option to track your keto diet macros. You can log meals using search, barcode scanning or photos (photo logging requires Premium), making it flexible and user-friendly no matter what method(s) you prefer. The food database is large enough to accommodate most dieters, and you have access to meal planners, recipes, community forums and more. Total and net carbs are shown as you log and the user interface is simple.

• The Pros: As another free keto tracker app option, this one is full-featured and easy to use, and lets you set your own carb limits and track water intake. It's applicable for Keto, Atkins, Paleo and other low-carb approaches. You can also chart weight and progress against your personalized goals, log ketones and blood glucose, and access it via the web or mobile device. It syncs with Fitbit, Garmin, Apple Health and Google Fit.
• The Cons: Several of the most useful features, including photo logging, premade meal plans and the premium recipe database, require a Premium subscription. It can sometimes be challenging to search for and add your own food items from a personalized meal plan.
• Cost: Free with a paid Premium subscription
• Platforms: Web app, mobile app on Apple and Android

Lifesum

Lifesum is another food and fitness tracking app available on mobile devices that offers calorie tracking, recipes and nutrition tips, and now markets itself as an AI calorie tracker. It offers a dedicated keto program and keto meal plans. The app's food rating guide also makes it easy to quickly assess the foods with the best nutritional value versus those that are high in calories, saturated fats, sodium or sugar.

• The Pros: Track meals and physical activity through an easy user interface and pick from structured programs, including keto. It syncs with Apple Health, Apple Watch, Health Connect, Samsung Health and Wear OS.
• The Cons: In our original review the food database was smaller than MyFitnessPal's and some nutrient information was inaccurate. Significant features, including the fuller set of plans and recipes, require a paid Premium upgrade.
• Cost: Free with a paid Premium subscription
• Platforms: Mobile app available on Apple and Android

Total Keto Diet (no longer actively updated)

2026 status: Total Keto Diet is still listed in the App Store and on Google Play, but neither listing has been updated since mid-2023. We would not recommend starting new clients on an app that is no longer being maintained.

The Total Keto Diet app offers a wide variety of healthy recipes for people on the keto diet plan, as well as educational articles on the ketogenic lifestyle in general. You can select and save your favorite meals and recipes and from that, create a personalized shopping list. The keto tracker app also includes a macronutrient tracker with total or net carb options, helping you log carb intake and overall diet macros.

• The Pros: This is an easy and convenient way to keep track of your keto plan and weight-loss progress, and offers an easy spot for keto education and logging of shopping lists.
• The Cons: No updates since 2023. For users that want to track other health metrics through integration with other devices or apps, this may simply be too basic. In our original review it was also difficult to adjust the amount of specific food entered (i.e. entering ½ cup of cooked cauliflower).
• Cost: Free with in-app purchases (Premium, custom meal plans, ad removal)
• Platforms: Mobile app available on Apple and Android

Cronometer (new for 2026)

Cronometer was not in our original 2019 roundup, but it has become a popular choice for detail-oriented keto dieters. It tracks a broad range of micronutrients, includes a keto calculator for setting macro targets, and can sync blood ketone readings from Keto-Mojo meters automatically.

• The Pros: Detailed micronutrient tracking, a keto macro calculator, and ketone meter syncing. It also integrates with Heads Up, so practitioners can see nutrition data next to labs and wearables.
• The Cons: The level of detail can feel like overkill for casual users, and some features, such as the Ketogenic Nutrition Score, require the paid Gold tier.
• Cost: Free with a paid Gold subscription
• Platforms: Web app, mobile app on Apple and Android

When FREE Falls a Little Too Short

KetoDiet App

When you're ready to step into the paid keto app world for more robust features, the KetoDiet app (now listed as "KetoDiet: Fasting & Meal Plans") offers more to help users adopt a healthier lifestyle rather than just losing weight at any cost. For people interested in following a low-carb eating plan with a high degree of accuracy, this is a great choice. Its meal planner builds weekly keto plans and can auto-fill meals and snacks to fit your remaining macros. Beyond calorie counting and carb monitoring, the app tracks net carbs and macros, includes a macro calculator, more than 2,000 low-carb recipes and grouped shopping lists, and since our original review has added an intermittent fasting tracker and an AI assistant.

• The Pros: Its simple interface is user-friendly, and the diet guide is well-suited for beginners and advanced keto dieters, with recipes formulated for keto via a whole-foods lens. Progress tracking covers weight, body measurements, ketones, blood glucose and lipids, with Apple Health integration.
• The Cons: Although the app is user-friendly, it is sometimes considered time-consuming to use. In our original review, measuring options for some items were only in ounces or grams, not cups, tablespoons or teaspoons, so volume accuracy could be a challenge on the fly.
• Price: Free download; Premium subscription unlocks the full feature set (listed in the US App Store at $12.99 per month or $79.99 per year as of October 2026)
• Platforms: Apple and Android

Heads Up: For Practitioners Running Keto Programs

When this article was first published, Heads Up was a personal health app. Today, Heads Up is a clinical intelligence platform for practitioners, so it sits alongside whichever keto tracker your clients prefer rather than replacing it. If you run a keto program, Heads Up unifies the data from those apps with labs, wearables, medical devices and EHR data in one longitudinal patient record.

Heads Up has 100+ device, lab and EHR integrations, including food trackers like MyFitnessPal and Cronometer, ketone meters like Keto-Mojo, CGMs like Dexcom, wearables like Oura and Apple Health, and labs like Labcorp and Quest. In fact, whatever keto tracker app your client decides to use, Heads Up helps you see the big picture of their health.

• The Pros: See a client's macros, ketones, glucose, weight and lab results together, instead of asking for screenshots. Set up keto as a program or protocol with adherence tracking, use threshold alerts to flag readings that need attention, and let the AI copilot prepare pre-visit briefs that summarize what changed since the last visit. Lab PDFs are extracted automatically, and clients use the companion app on iOS and Android. Heads Up is HIPAA compliant and SOC 2 Type II.
• The Cons: Heads Up is built for practices, not for individuals tracking keto on their own. For individuals, any of the apps above is the right starting point.
• Price: Month-to-month practice plans (see pricing)
• Platforms: Web platform for practitioners; client companion app for iOS and Android

The Bottom Line

The list of keto diet tracking apps is wide and long, and clearly, there is a lot of overlap between options, especially when it comes to the free ones. Since 2019, many features that used to be free (like barcode scanning in MyFitnessPal) have moved into paid tiers, and at least one app on our original list has stopped receiving updates. So the best way to choose? Start with the end in mind. If it's a diet plan and you're on a budget, a free tier is the way to go. If you want deeper macro and micronutrient tracking, a paid tier is worth it. And if you're a practitioner who needs to monitor ketogenic ratios, ketones and labs across many clients over the short and long term, pair your clients' preferred tracker with a platform built for that job.
