Despite some strong language I’ve used in the past, I don’t believe that weight loss apps are inherently evil. At the same time, you’re putting a whole lot of trust into this kind of app, and that can go poorly. You’re depending on it to tell you how many calories you need, to accurately tell you how many calories you’re eating and burning, to calculate how many calories you need in the first place, and to effectively motivate you toward healthy goals so you can see healthy results. You’re trusting an app to be a calculator, a coach, and a confidante. So, how do you decide which weight loss app is the right one for you?

Both Noom and MyFitnessPal are heavyweights in the fitness tracking arena. I’ve used both over the years to various results, and I can confidently report firsthand the pros and cons of each. Here’s what to know to decide which app deserves a place on your home screen, depending on how exactly you want to reach your goals.

Different weight loss philosophies

MyFitnessPal is the household name of calorie-counting apps, and it’s certainly designed to have mass appeal. It’s essentially a sophisticated food diary that helps you stay within your calorie budget through pretty straightforward tracking. There’s no hand-holding or psychological deep dives—just data, goals, and accountability through numbers.

Noom, on the other hand, positions itself as a psychology-based weight loss program that aims to change your relationship with food through behavioral science, daily lessons, and cognitive strategies. The idea here is to be less about restriction and more about understanding why you eat what you eat. If you’re someone who has always struggled with an overly simplistic “calories in, calories out” approach to weight loss, then Noom’s philosophy is a blessing. Then again, how “anti-diet” can a diet app really be? Let’s keep digging in.

Pricing

If your deciding factor is less about your philosophy and more about your wallet, here’s what to know.

MyFitnessPal offers a genuinely functional free version that includes basic food tracking, exercise logging, and access to its massive food database. If you’re willing to live without some bells and whistles, you can use MyFitnessPal indefinitely without paying a dime. The Premium version costs $79.99 per year or $19.99 per month, which gets you features like barcode scanning, meal scanning, custom macros, intermittent fasting tracking, and an ad-free experience. There’s another tier, Premium+, for $99.99 per year or $24.99 per month, where you get everything in Premium plus a meal planner.

Noom takes a subscription-only approach with no free version beyond a 14-day trial period. Pricing varies based on commitment length, typically starting around $42-70 per month for shorter subscriptions, with the 12-month plan bringing the monthly cost down to approximately $17.42 per month. The most common entry point is a four-month subscription at $169 (about $42.25/month).

Winner: MyFitnessPal for budget-conscious users; Noom’s lowest monthly rate requires a long-term commitment.

User interface

MyFitnessPal features a clean, straightforward interface focused on data entry. The home screen displays your calorie budget, macronutrients, and a simple diary for logging meals and exercise. It’s efficient and no-nonsense—perfect if you want to log your lunch and move on with your day. However, I can see why some users find it clinical and uninspiring, to say the least.

Noom offers a more colorful, engaging interface with multiple sections including food logging, lessons, group chat, and progress tracking. The app uses its signature color-coding system (green, yellow, red) to categorize foods based on calorie density. While this makes the app feel more interactive, and perhaps even game-like, it also means more screen time. Noom acknowledges you’ll spend about 15 minutes per day in the app, and there are plenty of animations to keep you around. Some users might find this engaging; I find it insidious. Remember, Noom doesn’t actually transcend the classic “calories = bad” formula here. It just color-codes it.

Winner: MyFitnessPal for quick loggers; Noom for those who want an engaging daily experience.

Food database and logging accuracy

MyFitnessPal** **has an extensive food database, with a huge caveat. This database is largely user-generated, which is both a blessing and a curse—you can find virtually anything, but accuracy can vary wildly. Premium users get barcode scanning and meal scanning features for faster logging.

Noom claims a database of 3.7+ million food items, though users frequently report accuracy issues. The app focuses more on its color-coding system than precise nutritional breakdowns. While you can scan barcodes and log food, the database isn’t as robust or reliable as MyFitnessPal’s according to user reports.

Winner: MyFitnessPal.

Recipe logging and meal planning

MyFitnessPal allows you to create custom recipes and save your favorite meals for quick logging. You can input all ingredients, specify servings, and the app calculates nutritional information per serving. It’s a beloved feature for home cooks. The Premium version offers curated meal plans.

Noom allows recipe creation, but the feature isn’t as refined or user-friendly as MyFitnessPal’s. Again, Noom focuses less on meal planning specifics and more on teaching you to make better choices instinctively through educational content.

Winner: MyFitnessPal.

Education and behavior change

MyFitnessPal is the world’s default calorie tracker. It provides basic nutritional insights and tracks your progress over time, but it doesn’t offer structured education or behavioral coaching. You’re expected to know what to do with the data you’re collecting.

What do you think so far?

This is where Noom differentiates itself with claims of being more than just a diet app. It’s built around daily psychology-based lessons that teach you about nutrition, habit formation, emotional eating, and cognitive behavioral techniques. You’ll complete a 10-minute quiz at the start to personalize your program, then receive articles and interactive content daily. It might not be for me, but I personally know many users find this educational approach more sustainable than simple calorie counting. Depending on your subscription, you may also get access to a personal coach and group support.

Winner: Noom.

Exercise tracking and integration

MyFitnessPal easily syncs with fitness apps and wearables (Fitbit, Apple Health, Garmin, Strava, etc.) and adjusts your calorie budget based on activity. You can manually log workouts or let your devices do the work.

Noom includes basic exercise tracking and syncs with some popular apps and devices, but it’s not the app’s primary focus. Noom encourages physical activity but emphasizes that weight loss is primarily driven by food choices.

Winner: MyFitnessPal.

Community and support

MyFitnessPal offers community forums where users can connect, share tips, and support each other. It’s a helpful resource, but feels somewhat disconnected from the core app experience.

Noom integrates community support directly into the app through group chats where you can interact with others on similar timelines. Higher-tier subscriptions include one-on-one coaching, which can provide personalized guidance and accountability.

Winner: Noom for integrated support; MyFitnessPal for self-directed community seekers.

The bottom line

There’s no universal winner here—it depends entirely on your needs, budget, and learning style.

Choose MyFitnessPal if you want a free or budget-friendly option, already understand nutrition basics, and prefer straightforward calorie tracking. It’s perfect for people who are self-motivated, enjoy analyzing data, and want freedom without forced education.

Choose Noom if you’re seeking more than just a food diary—if you want to understand the psychology behind your eating habits and build lasting behavior change. Yes, it’s significantly more expensive, but if you haven’t had success with traditional calorie counting, you’re paying for structured education, coaching options, and a comprehensive program rather than just a tracking tool.

For many people, the decision comes down to this: Do you need someone to teach you how to fish, or do you already know how and just need a good fishing rod? MyFitnessPal is the rod. Noom is the fishing instructor who’ll teach you techniques and check in on your progress.
