The 8 Best Keto Apps of 2021

Best Overall: Carb Manager

Sign Up Now

Carb manager takes “Best Overall” for best keto diet apps because it’s one of the most comprehensive on the market. You can track all of the basic metrics that are critical to the keto diet—like total carbs, net carbs, and fats—but you can also track ketones, blood glucose, insulin, glycemic load, and more.

On top of all that, you can track metrics that aren’t necessarily related to your diet but help you to maintain an overall healthy lifestyle, including water intake, exercise, and body weight.

Carb Manager has a food database that’s more than one million foods strong and offers barcode scanning, photo logging, and voice command logging. You can sync Carb Manager to your Fitbit, Apple Watch, or other supported device, as well as connect it to several other health and fitness apps. This app also offers a wealth of recipes, educational content, grocery list building, and a community platform.

Best for Tracking Nutrients: MyMacros+

MyMacros+ has held a steady reign in the nutrient-tracking world, due largely in part to its massive food database (more than five 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. For instance, you can log all of your macronutrients, including carbohydrates and net carbs, protein, and fats. 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.

Best for Beginners: Senza

Senza values simplicity, making it an ideal keto diet platform for beginners. With the introductory “5 Days to Keto” program, Senza guides you through the transition from your current diet—which may be carb-heavy if you’re used to eating a typical western diet—to the keto diet without making you feel miserable.

In your Senza Food Journal, you’ll track carbs and net carbs, as well as other keto nutrition metrics such as glucose and ketones. You can scan barcodes, search restaurant menus, or select from more than one million keto items in the food database. On top of those great features, you can track mood and sleep, and connect Senza to your Fitbit or Apple Watch to integrate other metrics.

Oh, and if you’re traveling? The app’s Keto Radar feature maps out keto-friendly restaurants near you—no more sifting through hundreds of Google search results to find a compliant restaurant.

Best for Finding Recipes: Total Keto Diet

Sign Up Now

Total Keto Diet by Tasteaholics is fantastic for beginners and keto experts alike. Tasteaholics is a free low-carb educational resource with thousands of recipes, keto news, blog articles, and more. The Total Keto Diet app encompasses the educational aspect of Tasteaholics while also providing a keto calculator, macro tracker, food database, and beginner’s keto guide.

On the app, you’ll also find an expansive recipe library and a shopping list feature where you can add ingredients from Total Keto Diet recipes or your own recipes. Total Keto Diet shares recipes that adhere to three main goals: They’ll keep your net carb count to under 25 grams daily, help you increase your protein intake to at least 60 grams daily, and satisfy both your taste buds and your belly. 

Best for Community: KetoDiet

Sign Up Now

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.

Best for Integrating Fitness: 8fit

Sign Up Now

8fit brings the best of both worlds—fitness and nutrition—together. The fact of the matter is that you can’t out-exercise an unhealthy diet, and nutrition alone won’t get you to all of your goals, especially if “toning” or building muscle is in the mix. With 8fit, you can keep track of your fitness goals and your nutrition goals in one organized place.

While not necessarily built just for keto dieters, 8fit allows you to track macronutrients, including carbohydrates and net carbs. With nearly a thousand nutritionist-approved recipes, you can use the diet filter to build out a healthy keto meal plan on 8fit and then use the shopping list feature to plan your trip to the grocery store.

On 8fit, you’ll find educational content (such as guides and tip sheets) on nutrition and fitness, research-backed workout plans, meal plan templates, instructional videos, and much more.

Best for Goal Setting: FatSecret

Sign Up Now

FatSecret has all of the features you need to cultivate a perfectly healthy keto lifestyle. You can set overarching goals, such as body weight, as well as smaller goals for each individual macronutrient. For example, you can set a daily goal and a weekly goal for carbohydrate intake to make sure you remain in ketosis. 

Just a few of FatSecret’s great features include: A comprehensive food diary to keep track of your food intake; an exercise diary to record your exercise sessions, calories burned, and fitness goals; a robust collection of healthy recipes; a weight chart to view your progress over time; and image recognition of foods to make food logging even easier.

Reminders and push notifications for meals, weigh-ins, and journal entries help you stay on track; a community platform helps you remain motivated to crush your diet goals; and a detailed overview of your daily, weekly, and monthly macronutrient breakdown helps you stay on top of your nutrition.

Best for Meal Planning: PlateJoy

Sign Up Now

PlateJoy isn’t designed only for people on a keto diet, but it certainly supports them. If you’re at a loss for keto meal ideas, get bored with your current recipes, or otherwise just can’t seem to stick to your keto meal plan, PlateJoy can solve all of that. Starting at just $8 per month, you can get nutritionist-developed keto meal plans, recipes, and grocery lists that can save you so much time and frustration.

When you download PlateJoy, you’ll start by taking a lifestyle quiz that asks about your taste preferences, health and fitness goals, dietary restrictions, allergies, and schedule. For keto, you’d want to make sure to highlight carbohydrate intake when the app asks about dietary restrictions. After you take the quiz, PlateJoy uses a smart algorithm to create a customized meal plan based on the information you provided. In the case of a keto meal plan, you’ll get hundreds of low-carb or zero-carb recipes for breakfast, lunch, and dinner.
