If you’ve got fitness or weight loss goals, using a macro calculator is a simple method for understanding what goes into your body.
Protein, fat, and carbohydrates are the three macronutrients essential for achieving and maintaining optimal physical health.
As long as you’re keeping track of these three things (along with caloric intake), you’ll be able to know if your diet is on the right track or not. Consuming too much or too little of them can hinder your ability to reach body-specific fitness goals.
That’s where a macro calculator comes in.
Instead of guessing your daily calorie intake and hoping for the best, a macro calculator will do all the math for you in a simple and easy-to-understand way.
We’ve rounded up the best macronutrient calculators, apps, and websites so that you can take control of your diet and achieve every goal on your list.

Top 9 Macro Trackers & Calculators
- MyFitnessPal
- Strongr Fastr
- IIFYM
- Nutritionix
- Carb Manager
- MyMacros+
- LoseIt!
- Life Sum
- MyPlate
We’ll break down each of these macro trackers to help you decide which best fits your needs.
1. MyFitnessPal
Because of its ease of use and extensive food database, MyFitnessPal is one of the best free macro tracking apps on the market. With a straightforward design and high compatibility with other apps, it’s easy to see why this fitness calculator has been downloaded over 40 million times!
MyFitnessPal gives you daily diet feedback, tracking how many macros you’ve consumed and how many you have left in a clear and aesthetic way. You can also connect with others on the app and track your progress together for a more social spin on app-based fitness.
However, if you want to view your macros percentages and nutrient goals, you’ll have to upgrade to the Premium version, which costs $79.99 per year. For such a competent macro tracker, the price is more than worth it for some people.
If you want to give it a try, start with the free version. It may meet all of your needs without the need to upgrade to the paid plan.
If you’re completely lost and don’t know where to start, MyFitnessPal is a reliable pick.
2. Strongr Fastr
This macro calculator doubles as a meal planner, using the information you provide about your body to curate a diet plan that meets your exact needs. If you have very precise body fat or fitness goals in mind, this app can provide you with all the necessary tools for creating (and sticking to) a solid macro diet.
Featuring an automatic macro calculator, a comprehensive diet planner, and an advanced tab for measuring specific macro goals.
There are even resources available for easy meal plans, workout schedules, and an extension for professionals who manage multiple macro plans at once.
You can find Strongr Fastr software online and use a free trial to get started.Â
3. IIFYM
IIFYM, an acronym for If It Fits Your Macros is a great choice for a free macro calculator.
If you want to track your macros, but you’re not sure how many grams of fat, protein, and carbohydrates you should be consuming each day, IIFYM can help you figure that out.
You will need to give them your email address to receive the full results, but it’s a quick and painless way to get started on your macro tracking journey. I’ve personally used IIFYM and found them to be a helpful tool.
4. Nutritionix Â
If you’re big on eating out but struggle to gauge what meals to pick, Nutritionix would make a great macro calculator for you. With a library of foods from over 800 restaurants in the US, this app is perfect for beginner macro trackers who lack experience with food and nutritional evaluation.
Developed by professional dieticians, you can trust that Nutritionix will provide you with the right information for developing a macro diet that suits both your body and food preferences.
The app shows you your daily macro totals in a clear, simple format, and even allows you to upload your own recipes for added personalization.
Nutritionix is 100% free with no tiered payment systems, so you never have to worry about limited access to resources.
5. Carb Manager
If carbs are something you struggle to understand or limit, Carb Manager offers a great solution. With a strong built-in macro calculator and impressive data-tracking abilities, this beginner-friendly app makes food tracking a walk in the park.
Originally designed for people following the keto diet, Carb Manager offers unique recipe ideas, food libraries, and the ability to connect with other users on the app. At once social and practical, this app can be downloaded on either iOS or Android for reliable macro tracking.
6. MyMacros+
MyMacros+ has been voted one of the best overall macro calculators currently available. Featuring a wide-ranging food library, simple software design, and an extremely user-friendly calendar, this app is perfect for anyone who wants to kick-start their fitness journey with the basics.
Leaning more towards the food diary category, MyMacros+ can be downloaded onto Android or iOS, costing just $2.99 as a once-off payment. If you want, there are Pro and Coach payment tiers that come with a variety of additional perks like custom menus, diet summaries, and automatic target updates.
Another special feature of this app that is available on every tier is its barcode scanner, allowing you to quickly scan food and supplemental products for their macro content.
7. LoseIt!
As one might guess by its name, LoseIt! is an app designed for people whose main macro-tracking goals revolve around weight loss. It syncs up well with other fitness apps and features a wide range of useful tips and tricks for keeping body fat low while gaining physical strength.
If you are looking for an intuitive, easy-to-use app for weight loss, LoseIt! is a great macro calculator to choose. Most of the features are free, but premium users get access to special features like barcode scanning and carb tracking for just $39.99 per year.
8. LifeSum
LifeSum is best known for its wealth of creative food recipes and meal plans that suit anyone’s tastes—no matter how picky. Available on both iOS and Android, this app has an extremely clean, user-friendly app interface and a variety of special features to make it memorable.
LifeSum really adds structure and substance to the process of macro calculation, boasting exciting meal plans that other apps just don’t hold a candle to.
The free version of this app includes calorie tracking, exercise guidance, and food tips, but you’ll need to upgrade to the premium version if you want access to things like tailored shopping lists, coaching advice, and specialized recipes—but for just $49.99 a year, it’s definitely worth it.
9. MyPlate
MyPlate is a recently developed app dedicated to helping people strategize their calorie consumption for the sake of improving strength, flexibility, or weight loss. With special features like tracking sodium, sugar, and fiber intake, MyPlate is a great app for experienced macro trackers.
The food database for this app includes over 2 million items, and you’ll have access to a nifty barcode scanner that makes shopping much easier. Available on Android and iOS, MyPlate is both easy to use and highly effective.
Take the stress out of tracking your macros. Use any of these recommended trackers to meet your goals!
