Best Keto Apps

The keto diet (or ketogenic diet) has become one of the most popular diets in recent years. Ketogenic eating encourages the body to burn fat, as opposed to glucose, by avoiding carbs and focusing on a high-fat diet.

While high fat may seem intimidating and even counter-productive, it’s important to remember that some fats are better for your body than others. Fatty fish, avocadoes, nuts, and olive oil are all sources of healthy fats that are ideal for the keto diet. Dieters may want to steer clear of oils high in polyunsaturated omega-6 fats, such as soy, corn, cottonseed, and safflower, which are less healthy than the fat sources listed above.

As always, it’s best to consult your doctor and/or a nutritionist before starting any new diet. The ketogenic diet may not be appropriate for patients with certain medical conditions, such as pancreatitis, liver failure, disorders of fat metabolism, among others, according to medical professionals. The diet also may not be safe during pregnancy.

Typically, those following a keto diet consume 70% to 75% of their calories from fat, 5% to 10% of calories from carbohydrates, and the rest from protein. The math can be hard to figure out, but there are a lot of apps out there to help you track your macronutrients (often called macros), or your percentage of fats, carbs, and proteins, to give you awesome meal ideas, to find community encouragement when things get tough and more. We’ve listed the best apps to help maintain an effective keto diet.

MyMacros+ has held a steady reign in the nutrient-tracking world, due largely in part to its massive food database (more than 5 million foods!) and simple app interface. With MyMacros+, tracking your meals is no longer frustrating and time-consuming. Rather, it’s easy, quick, and honestly quite fun when you see all of your great progress.

MyMacros+ isn’t strictly a keto diet app, but it does support everything a keto dieter would need.

The app supports the logging of other nutrients that are important to the keto diet, too, such as sugar and fiber.

With this app, you can log unlimited meals throughout the day and see how your dietary choices affect your set goals (which you can modify at any time in your settings). MyMacros+ shows you the nutritional breakdown of every ingredient, meal, and day. Perhaps the best part? The logging feature is usable without the internet, so if you find yourself eating somewhere without service, you can still accurately log your meal.

  • Pricing: Free, with in-app purchases

Why We Chose It: Maintaining a keto diet definitely takes some motivation, and the KetoDiet app provides just that, offering challenges and creating an online community atmosphere. We also love the accuracy of its food database for proper diet tracking.


  • Nutrient data is verified for accuracy
  • Competitive challenges and Facebook support group for accountability
  • Recipes are tasty
  • Intuitive user interface, easy to use

  • Customer service is lacking if you have issues with your account
  • Not possible to customize meal plans using different macros

Do you thrive in group settings and with a little bit of competition? If so, KetoDiet is the perfect keto app for you. Of course, the app offers all of the critical components of a keto diet app: carb and net carb tracking, macro tracking, body weight, and body fat tracking, recipes, etc. But it also offers KetoDiet Challenges and a Facebook support group, both of which can keep you motivated to stick to your low-carb diet.

Another great thing about KetoDiet is the accuracy of its food database. The app centers around the idea that accuracy is crucial for success on keto, so it doesn’t crowdsource nutrition data, unlike many other diet apps. That means KetoDiet gets all of its nutrition information from trustworthy, verified sources (such as the USDA) rather than allowing app users to upload nutritional information into a common database.

Final Verdict

Whether you’re new to a ketogenic diet or have been maintaining a keto lifestyle for some time, an app can greatly assist you in tracking your macros and keeping you on the path to reaching your health goals. Our favorite apps on this list are Carb Manager and MyMacros+. We think the most important thing to pay attention to when starting a keto diet is your macros by keeping a detailed food diary. Carb Manager’s comprehensive approach allows you to track detailed fitness information, keeping you informed of your progress. We also love MyMacros+ because of its food database, which keeps you accurate in your meal logging.
