If you’re trying to lose weight or achieve another nutrition or fitness goal, a weight loss app may help. Research finds that consistently tracking calories and exercise is an effective strategy for weight management.

These programs download directly to your phone, offering a quick and easy way to log meals, workouts, and more.

Tracking behavior in this way can be enlightening, says Janelle Duah, MD, an obesity specialist at Yale Medicine and an assistant professor of general medicine at Yale University Medical School.

“These features can open [their] eyes to making healthier food choices, help them to recognize maladaptive patterns in their dietary habits, assist in them becoming aware of great choices they can be more consistent with, or even realize issues with inactivity or sedentary habits that need to be changed for overall health.”

Here are the six best weight loss apps, according to health experts and users.

Healthline’s picks for weight loss apps

Best for behavior modification

Noom

Subscription cost: $59 per month or $199 per year
iPhone rating: 4.7
Android rating: 4.4
Requires a monthly membership or subscription: yes

GET STARTED WITH NOOM

Healthline's review

What we like about it: Noom makes the nuts and bolts of weight loss (calories in/calories out) both educational and fun. Using quizzes, humor, and very human language, it’s like talking with a nonjudgemental friend. But along the way, you’re learning real and useful information about habit formation, how metabolism works, and what it actually takes to lose weight sensibly and to keep it off.

It’s also backed by research. One study of more than 500 adults found that food and exercise logging, along with coaching through Noom, was more effective for weight loss over 6 months than food logging or personalized coaching alone.

A newer feature, Success Kit, provides support resources like grocery planning, healthy food swaps, workouts, and meditations.

How it works: Using information you provide through a series of prompts, Noom generates a customized plan that includes a timeline for your weight loss goals, a suggested daily calorie range, and behavioral encouragements, such as helping you to understand the “why” behind your goal.

In addition to meal tracking (and tracking other things, like water consumption and activity), it offers nutritional guidance by sorting foods into colored categories (green, yellow, orange), and offers daily reading with quizzes. You can also get ideas for food substitutions and recipes.

Plus, you’ll have a health coach who can provide accountability and help you set realistic weekly goals to keep you on track.

Noom subscription costs range from $70 per month to $209 per year, with costs dropping for longer subscriptions.

Considerations: As a calorie-counting tool, however, Noom may not be the right fit for everyone, as calorie counting can increase the risk of disordered eating in some people. Additionally, Noom’s color coding system may discourage consumption of higher calorie foods that are nonetheless nutritionally dense.

Best for community

WeightWatchers

Subscription cost: approximately $15–$65 per month
iPhone rating: 4.8
Android rating: 4.5
Requires a monthly membership or subscription: yes

GET STARTED WITH WEIGHT WATCHERS

Healthline's review

What we like about it: WW places a big emphasis on community and social networking, plus 24/7 live coaching for accountability and support. This may help some people feel less alone in their weight loss journey.

“A platform where application users can ‘follow’ other users who were in similar situations as themselves, thus reducing feelings of isolation and overwhelm that people can often experience, can also be helpful,” Duah said.

Plus, no foods are off limits with WW, also known as WeightWatchers, which uses a points system that’s based on nutrient content and calories. There’s also an extensive collection of recipes that you can search based on meal type and dietary requirements.

How it works: Based on the results of your online quiz, you’ll get a daily PersonalPoints allotment and a customized list of zero-point foods.

Then you’re ready to start tracking points, logging workouts, and monitoring weight trends all in the app.

WW offers three plans, all of which provide access to the WW app. Depending on which plan you choose, WW costs $10–$55 per month, though the company frequently offers monthly discounts to new customers.

24/7 live coaching
social networking with fellow WW members
weekly in-person workshops on some plans
app has a barcode scanner for uploading packaged foods
tracks points rather than calories

can be difficult for some to track points

Best for logging meals

Lose It! App

Subscription cost: free, optional subscription for $9.99 per month or $39.99 per year
Requires a monthly membership or subscription: no
iPhone rating: 4.8
Android rating: 4.4

GET STARTED WITH LOSE IT!

Healthline's review

What we like about it: The app is super user-friendly and has a huge database of more than 33 million foods, restaurant items, and brands. The Snap It feature makes logging a breeze by allowing you to simply take pictures of your meals. There’s also a convenient barcode scanner and recipe builder, and it’ll save foods that you enter frequently to make logging even more efficient.

Taking pictures of meals may help people keep track of portion sizes more accurately and observe trends in their dietary intake, both of which help promote weight loss, though overall, the research is mixed.

We love the focus on nonscale victories, such as lowering your cholesterol levels and feeling more energized, too.

How it works: Lose It! generates your personalized weight loss plan through an analysis of your weight, age, and health goals. Then, you simply start logging and, if you’d like, take part in the challenges and forums within the app.

Using the app is free, but additional features are unlocked with a premium subscription for $39 annually.

Consideration: Lose It! relies on food logging as a means of calorie counting, which has the potential to lead to a disordered relationship with food and body image in some people.

Best for intermittent fasting

Zero

Subscription cost: $9.99 month or $69.99 annual
iPnone rating:
Android rating: 4.6

GET STARTED

Healthline's review

What we like about it: For anyone exploring intermittent fasting as a weight management strategy, Zero has all the bells and whistles you need to jump in, from educational resources to a customizable fasting timer, tracking capabilities, and statistics to monitor your progress.

How it works: After signing up, users can get started with various fasting methods like 16:8, 5:2, or personalized schedules.

The premium version unlocks additional features such as expert guidance and advanced statistics for a more tailored fasting experience.

There is a free version of the app, but you can upgrade for additional features for $9.99 per month or $69.99 annually.

Consideration: If you’re looking for nutritional guidance, this may not be the right app choice for you.

user-friendly and straightforward
customizable fasting plans to suit individual needs
educational resources
high user ratings

some features, including expert advice and additional insights, require paid subscription
limited nutritional guidance on what to eat during non-fasting periods

Best for intuitive eating

Way App

Subscription cost: $6.99 per month or $49.99 per year
Requires a monthly membership or subscription: yes
iPhone rating: 3.5
Android rating: N/A

GET STARTED WITH EAT MY WAY

Healthline's review

What we like about it: Maybe you’re tired of focusing so much on pounds or inches, and you just want to feel you have a healthier relationship with food. Way is a unique app that takes an antidiet approach to health through mindful eating.

According to obesity specialist Janelle Duah, MD, for some people, apps that require tracking food, counting calories, and monitoring physical activity can have negative effects on their relationship with food and exercise.

Way’s emphasis on intuitive eating might be a fresh alternative.

It’s also worth noting that some research has found that actively dieting might actually make it more difficult to lose weight due to changes in the body’s metabolism, hunger, and fullness cues.

How it works: When you first sign up, the app will ask you questions designed to help you reflect on how eating foods makes you feel. The goal is to foster a healthy relationship with those foods.

There are more than 60 different activities in the app that are broken down into three pathways:

The Emotional Eats Pathway: This pathway reflects on how our emotions can affect our eating habits in a nonjudgmental way.
The Body Feels Pathway: It observes body image as well as physical health overall.
The Mindful Shifts Pathway: It asks questions about how we talk about ourselves when it comes to our lifestyle habits.

Overall, the reviews on the app are positive, with some calling it a safe space and a refreshing change to the traditional health apps out there. However, some have written reviews that mention the format of the app can be a bit buggy at times.

Way offers a free 14-day trial followed by a monthly cost of $6.99.

Consideration: Way is not designed for weight loss but to help people have a better relationship with food and their bodies.

has 60+ activities for users to work through

Best for grocery shopping

Fooducate App

Subscription cost: free, optional in-app purchases costing $9.99–$89.99
Requires a monthly membership or subscription: no
iPhone rating: 4.6
Android rating: 4.2

GET STARTED WITH FOODUCATE

Healthline's review

What we like about it: If you’re looking to make healthy choices on your next grocery run, this may be your answer. Fooducate’s easy-to-use scanner allows you to scan more than 250,000 product barcodes and receive detailed information about the food, flagging ingredients to look out for and even a list of healthier alternatives to purchase.

How it works: All you need to do is download the app and allow it access to your phone’s camera. Then you can start scanning your products.

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.

For example, if you scan a specific type of yogurt that contains a high amount of added sugar, the app will show you lower sugar options to look for instead.

The app is free to download, but certain features, such as micronutrient tracking and potential food allergy warnings, require a premium subscription ($6.99 per month).

has a grading system to help you choose according to your goals
tracks exercise and calories
can scan some products for allergens

many features, including support for some diets and allergen tracking, are available only with a paid upgrade

How to choose the best weight loss app

When deciding which weight loss app is right for you, there are a few factors to keep in mind, such as:

Budget: Many weight loss apps have a free version as well as the option to access premium features for an additional cost. Others require a subscription or a one-time purchase for use.
Special features: It’s important to consider the features you want an app to have, such as one-on-one coaching, meal planning and recipes, food and activity logs, barcode scanners, or macro-nutrient counting. Some apps can also sync to a wearable device, such as a fitness watch, to make activity tracking seamless and convenient.
Weight and wellness goals: Certain apps may be better suited for certain goals. For example, if your goal is to lose weight by increasing your activity level, it’s helpful to choose an app that offers recommended workouts and integrates with an activity tracker.
Your experience level: If you’re new to exercising and healthy eating, you’ll want an app that includes plenty of beginner-level resources or even one-on-one coaching.

Limitations of weight loss apps

While weight loss apps may be an effective tool for some, they aren’t foolproof and may not be accessible for everyone. “Using the apps takes a considerable amount of technological savvy, so may be hard for older or less tech-experienced people to gain benefit from consistent use,” said Duah.

Subscription costs can also be a barrier for some people to use weight loss apps, especially over longer periods of time.

Ultimately, Duah said, the person who will most benefit from a weight loss app will be “technologically capable, can afford to use it consistently, and is invested in their own weight management, engaged in the application which caters to their specific needs, and has dietary, psychological, and physical support when needed.”

Frequently asked questions

The apps on our list all provide good options to help people gain better awareness of their eating and other habits, which may help support weight loss. From there, there are different features that will appeal to different people.

If you’re looking for smart tech, a focus on behavioral therapy, and food and activity tracking, Noom might be a great fit.

Weight Watchers, or WW, is known for its community focus, which may be helpful more helpful to some, and takes some of the pressure off calorie counting with its points system.

Ultimately, the most effective weight loss app will depend on your needs and preferences. According to obesity medical specialist Janelle Duah, MD, the most effective weight loss apps will include:

• goal setting

• meal planning

• activity tracking

• ability to discuss with others either via social media-like platforms or with a coach

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.

The best free weight loss apps on our list are Fooducate, Lose It!, and Zero. Each offers valuable features in their free versions:

Fooducate provides a unique food grading system, helping users make choices that are healthier for them. It also includes basic food and exercise logging and community support, making it a comprehensive tool for health-aware individuals.
Lose It! features a comprehensive food database, barcode scanner, and basic exercise tracking. Its user-friendly interface is excellent for straightforward meal and activity logging, supporting effective weight management.
Zero offers a customizable fasting timer and tracks fasting history, making it a simple yet effective tool for fasting-based weight loss strategies.

While premium subscriptions offer additional features, these apps not only rank as the best weight loss apps free of charge but also offer comprehensive features for effective weight management.

Losing 20 pounds in a month is a goal that’s not recommended due to health concerns.

Rapid weight loss can lead to a range of issues, including muscle loss and nutritional deficiencies, and can negatively affect your overall health. It’s also unsustainable and can set you up for potential weight regain.

A healthier and more sustainable approach to weight loss involves setting realistic goals, focusing on gradual, steady weight loss – typically 0.5–2 pounds per week, as recommended by health professionals. This can be achieved through a balanced diet, regular physical activity, and lifestyle changes that promote overall well-being.

It’s always best to consult with a healthcare professional like a dietitian for personalized advice and safe weight management strategies.

The best weight loss program is one that aligns with your personal health goals, preferences, and lifestyle.

For example, Noom may be the best option for someone looking for 1:1 coaching, an interactive curriculum, and dietary tracking. In contrast, WW may be an ideal program for someone looking for a community-oriented approach with its vast support network.

Way is another potential program choice with its guided activities within the app.

Ultimately, the effectiveness of a weight loss program depends on consistent engagement with it and the ability to incorporate its principles into your daily life.
