Best Calorie & Macro Tracking App: 20+ Apps Tested
1. Ember
Ember offers daily AI-driven voice calls designed to provide personalized coaching and keep users accountable. Unlike text-based apps, its voice interactions create a deeper connection with users.
By combining Apple Health data with GPT-4 natural language processing, Ember tracks health metrics in real time and offers timely feedback tailored to the individual.
Ember focuses on several key areas:
- Daily activity levels
- Dietary habits, including keto and intermittent fasting
- Emotional well-being and motivation
- Trends in real-time health data
This multi-faceted approach resonates with users. For instance, Nathan P., a verified buyer, shares:
"Just wanted to say that I love this product. I have never been one who takes supplements but I must say Ember is top notch. Since taking Ember I have dropped three pounds. I am amazed by the results. I still have more to do in order to reach my goal and this is a great start."
Ember's vector storage system keeps a detailed log of your health journey, spotting patterns and offering guidance when you stray from your goals.
Need extra help? Ember's on-demand support lets you initiate calls for advice, acting like a personal coach available 24/7.
Backing these tools, clinical studies highlight the effectiveness of Ember's ingredients. CapsiMax™ has been shown to burn an additional 100 calories daily, while African mango seed extract supports weight loss and metabolic health.
Another user, Isabella B., appreciates the energy boost without the crash:
"Love the fact that I don't crash from the high caffeine content. I just feel nice and energetic. Also I only use half an ember ever and it's amazing!"

2. MyFitnessPal
MyFitnessPal has taken a major step forward in personalized meal planning by acquiring Intent, solidifying its place as a leader in AI-powered weight loss tools.
One of its standout features is Meal Scan, which uses Passio AI's Nutrition AI SDK to instantly identify foods via a smartphone camera. This tool matches images to a vast food database, making food tracking faster and more precise. These tools are designed to help users achieve measurable weight loss results.
Nearly half of daily active subscribers reported a 5% weight loss within four months. Dr. Zhaoping Li, a Professor of Medicine and Chief of Clinical Nutrition at UCLA, highlights the importance of food tracking:
"Those who actively logged food in MyFitnessPal and engaged more frequently with the app were statistically more likely to reach their weight loss goal within 4 months. This finding underscores the role of consistent food tracking as a cornerstone of progress towards weight loss goals."
Data shows that users who log meals at least four days in the first week are seven times more likely to hit their weight loss targets. Additionally, pilot studies reveal a 32% higher treatment adherence when using the app alongside GLP-1 medication.

As part of its future plans, MyFitnessPal will integrate Intent's technology to provide personalized meal plans and auto-generated grocery lists, exclusively available with the Premium+ membership.
3. Noom
Noom combines AI technology with psychological principles to help users achieve lasting weight loss. Unlike traditional calorie-counting apps, Noom emphasizes understanding the psychology behind eating habits.
A 2016 study involving nearly 36,000 Noom users revealed some impressive results:
- 78% of users lost weight over 9 months.
- 23% reduced their starting weight by more than 10%.
- 60% maintained their weight loss for over a year.
These stats highlight Noom's focus on long-term results. The app's AI tailors daily calorie goals based on factors like age, height, weight, and lifestyle. Noom also stands out with its color-coded food system that simplifies meal choices:
| Food Category | Description | Examples |
|---|---|---|
| Green | Lowest calorie density | Vegetables, fruits, whole grains |
| Yellow | Moderate calorie density | Lean proteins, legumes |
| Orange | Highest calorie density | Nuts, oils, processed foods |
Noom's co-founder and CEO, Saeju Jeong, explains their unique approach:
"We understood that once we applied psychology and the power of human empathy with tech, it bottled a path to healthy eating habits that are sustainable, too."
Beyond weight loss, Noom can also reduce healthcare expenses. On average, users spend $3,433.89 annually on healthcare compared to $3,884.28 for non-users.
Subscription Options
Noom offers flexible plans for its users:
| Plan Duration | Cost |
|---|---|
| Monthly | $70 |
| Annual | $199 |
| Noom Med (Add-on) | +$49/month |
Dr. Chris Mohr, Ph.D., RD, supports Noom's approach:
"Weight loss from the Noom diet can be real and sustainable if you stick with the daily habits... This diet intends to promote balanced eating and regular exercise, which are key to long-term weight management. It doesn't just focus on quick fixes but encourages gradual lifestyle changes."
The app adapts lesson durations, ranging from 1 to 12 minutes daily. This keeps users engaged while teaching healthier habits through techniques like cognitive behavioral therapy (CBT) and mindfulness-based stress reduction (MBSR).
Recent data shows that consistent users lose an average of 15.5 pounds in 16 weeks. Noom's success is reflected in its growth, with revenue hitting $500 million in 2023.
4. Lose It!
Lose It! has helped users shed a total of 149,782,393 pounds through its AI-driven weight management tools, including a voice logging feature with 98% speech-to-text accuracy.
Sarah Molhan, the principal product manager at Lose It!, explains the goal behind their features:
"We've always seen our job as finding ways to make those behaviors a bit less hard, and I think Voice Logging does just that."

Monica Ma, Lose It!'s senior principal UX designer, highlights the simplicity of their voice logging tool:
"By allowing members to log their food intake using just their voice, we are simplifying the process and making it more intuitive, especially for those who may struggle with traditional interfaces."
Registered dietitian Lena Bakovic underscores the value of tracking:
"One of the greatest benefits of using a calorie or macronutrient counting app is a sense of accountability and awareness for the user."
The app also lets users pick a pace that suits them, with data showing better long-term results for those who opt for less aggressive plans. Additionally, users who log their workouts lose weight faster - about 0.07 pounds per day compared to 0.05 pounds per day for those who don’t track exercises.
