The pricing structure assumes you are committed before you try it. Noom is a behavior-change program with a calorie tracker bolted on, not a calorie tracker with behavior change bolted on. If you do not want photo logging — and some people genuinely don’t — MacroFactor is the most credible recommendation in the category. The ads are noticeable but not intrusive enough to ruin the experience. For someone who just wants to log food and see their numbers, FatSecret does the job without asking for a subscription. The food database is curated — smaller than MyFitnessPal’s but with fewer junk entries and duplicates.
Most apps give you a static calorie number based on a formula. MacroFactor recalculates your targets weekly based on your actual weight trend data and food intake. If you are eating 2,200 calories a day and losing 0.3 pounds per week instead of your goal of 0.75 pounds per week, the app adjusts your target downward automatically. The site is clearly organized in different tabs, Beth explained. Under ‘Eat,’ you can access a meal planning system, which offers suggested meals and a shopping list.
Calorie Counter by FatSecret — Best for Food Journaling
The Simple app is our pick for the best weight loss app for iOS because it includes multiple features that will sync well with your Apple Watch or iPhone. There’s a home screen widget so you can see your fasting timer and other progress without having to open the app. Simple also syncs with Apple Watch, so you can start or finish a fasting period and track on your watch and have it sync up directly with your phone. Noom takes a psychology-first approach, combining calorie tracking with cognitive behavioral therapy lessons. It has carved out a niche for users who need mindset coaching alongside food logging.
Benefits of the Best Calorie Counter Apps

For people who need to change eating behavior — not just count calories — Noom is the best choice. The daily psychology-based lessons address emotional eating, habit loops, and cognitive biases around food. The clinical data supporting Noom is stronger than most competitors. The cost ranges from $42 to $209 depending on plan length, which puts it at the premium end. Weight loss apps work by creating a feedback loop between what you eat, how you move, and what your body does over time. You input data — food, activity, body weight — and the app processes that data into something actionable.
Can I use a calorie-counting app with a smartwatch?
MFP remains a solid choice for experienced trackers who know how to verify entries, but beginners are likely to encounter data quality issues that undermine trust and results. At roughly $70 per month, Noom is the most expensive option on this list. Many users report that the daily lessons become repetitive after 8-10 weeks, which contributes to a well-documented drop-off in engagement.
Best for intermittent fasting
To this list, you might add being easy to use and engaging enough that you want to stick with it. “In general, the longer a person uses an app, the better the outcomes,” adds Duah. If your product contains less healthy ingredients, such as trans fats and high fructose corn syrup, it will flag them for you and help you choose another product. Way offers a free 14-day trial followed by a monthly cost of $6.99. Our longterm tester Kim Currin has been testing Noom for all of 2025 since turning 40. Due to overweight, she’s managing several health conditions including PCOS, prediabetes, and back pain.
However, the interface, fast barcode scanning, and energy expenditure tracking with built-in coaching are well worth the cost. Registered dietitian Perry Nix appreciates the advanced nutrient tracking. “Cronometer tracks significantly more nutrients than most other tracking apps,” she says.
MyFitnessPal
The in-app BMI calculator is your go-to tool, crunching the numbers and providing you with a personalized calorie target. Listen, there are no generic solutions here as it’s all about tailoring the plan to fit your unique needs and goals. Noom stands out with its holistic approach to weight loss as it goes beyond calorie counting, focusing on building sustainable habits. Now, what sets Noom apart among the best weight loss apps is its proven track record. We considered if programs use a specific dietary pattern (such as intermittent fasting, portion‑control, or a food‑group–based approach) and how flexible that pattern is in day‑to‑day life.
Best Weight Loss App for Tracking Macros: Cronometer
You can choose programs that are suitable to perform at home. It is believed that doing the exercises during this time will allow you to lose weight and tighten your body. You can even take a photo of your meals to get an estimate of how many calories it contains. The app includes a helpful water-tracking feature that reminds you to stay hydrated throughout the day, too. Beyond those features, the app includes more than 300 cardio and strength workouts for a more well-rounded approach to your health and fitness. It even integrates with Apple’s HealthKit and the MapMyRun, Garmin, and Fitbit apps to accurately track steps and workout routines.

Sometimes, a weight loss journey can feel socially isolating. It often requires lifestyle changes and adjustments to your eating habits that can also change how you interact with some of the people in your life. There are also a lot of features, like a recipe database, workout routines, and intermittent fasting tracking. All recipes also have a detailed macro breakdown, which is helpful for those who want to track food choices beyond calories. Cronometer is a robust nutrition tracker, allowing you to track up to 84 different nutrients in your diet.
The 6 Best Weight Loss Programs of 2026: Chosen by Our Expert Testers
He rated the accountability features of the app as a 4 out of 5. “There isn’t a community feature or personalized coaching. The app does have an AI assistant, which can answer questions and provide guidance on healthy recipes and workout ideas,” Pete said.
We also considered whether the app ran smoothly or if it was glitchy and constantly rebooting. Weight loss is a billion dollar industry, so it’s not surprising that there are hundreds of apps that promise to help you on the journey. But as we know with supplements and most health products, you can’t take claims at face value. Like more basic apps, you can, of course, input your current weight and monitor your progress toward your goal weight. If you’re a beginner, this might be a bit of a harna reviews deterrent because you’ll need some time to figure out your body and what works best for you. But otherwise, we think this is a great option for most people.
Welling vs. MyFitnessPal
As a nutrition coach, one feature I particularly love about Cronometer is the verified food database. The Nutrola weight loss app for Android supports full offline functionality, including food search and logging from its cached database. Most competitors offer only partial offline support, typically limited to recently viewed foods. Noom and Yazio have the most limited offline capabilities. MacroFactor uses an expenditure algorithm that adjusts your calorie targets weekly based on actual weight trends. The food database is curated but smaller than competitors.
MyFitnessPal takes the podium for its simplicity and effectiveness. This weight loss app for iPhone doesn’t box you into a restrictive diet, unlike others. Instead, it’s your health guide to understanding habits, making informed food choices, and achieving your wellness goals. In this blog, we discuss the 6 best weight loss apps that adapt to your pace, your goals, and your lifestyle. The most effective program is typically the one you can follow consistently while maintaining your physical and mental health. We picked Noom as our overall best program for weight loss; we like its daily lessons, structured tracking, and built-in coaching along with community support.
The Nutrola weight loss app for Android delivers all three of these Android advantages in a single package. The difference between a weight loss app that supports Android and a weight loss app built for Android is enormous. You do not need to manually enter workouts or reconcile data between apps. Most users who track consistently see measurable weight loss within 2-4 weeks.
