There are dozens of food tracking apps on the App Store and Google Play. Most of them do the same thing: count calories. But "food diary" means very different things to different people. Some people want to lose weight. Some need to manage IBS. Some just want to figure out why they feel terrible after lunch every single day.
That difference matters. Downloading the wrong food diary app is like buying running shoes for hiking. It technically works, but you're going to have a bad time.
This guide compares six of the best food diary apps across different use cases. We're not ranking them 1 through 6, because the "best" app depends entirely on what question you're trying to answer about your food.
What to Look For in a Food Diary App
Before picking an app, get clear on what you actually need. Here are the five things that matter most.
What is the app actually tracking? Some apps track calories and macronutrients. Others track symptoms like bloating or headaches. Others track how you feel: your energy, mood, and digestion. These are fundamentally different tools solving different problems. A calorie tracker won't help you find food sensitivities. A symptom tracker won't help you hit your protein goals.
How fast is logging? The best food diary app is the one you actually use. If logging a meal takes 3 minutes of searching through databases and weighing portions, you'll quit within a week. Look for barcode scanning, voice input, or quick free-text entry depending on what you need to record.
Where does your data go? Food logs are personal. Some apps store everything on their cloud servers. Some sell anonymized data to third parties. Some keep everything on your device. If you're logging symptoms, digestive issues, or health data, you should know exactly who can see it.
What does it cost? Free tiers vary wildly. Some are genuinely useful. Others are so stripped down that they're basically a demo. Monthly subscriptions range from $5 to $70+. Know what you're paying for before you commit.
Does it provide insights, or just store data? Logging food without getting anything back is just data entry. The best apps actually help you see patterns, whether that's calorie trends, symptom correlations, or feeling patterns over time.
The 6 Best Food Diary Apps, Compared
1. MyFitnessPal
The calorie counter that started it all
MyFitnessPal has been the default food diary app for over a decade. Its biggest strength is its food database: over 14 million verified items. Scan a barcode, and it almost always finds the product. You get detailed macro breakdowns (protein, carbs, fat), integration with fitness trackers like Garmin and Apple Watch, and meal planning tools.
It works well for what it does. If your goal is tracking calories to lose weight or hitting specific macros for bodybuilding, MyFitnessPal is the most complete tool available.
That said, it does nothing to help you understand how food makes you feel. There's no symptom tracking, no mood logging, no energy scores. The free tier is cluttered with ads. And after the app was acquired by Francisco Partners (following its years under Under Armour), there have been ongoing concerns about data privacy, especially after a data breach that affected 150 million accounts in 2018.
Pros
- Largest food database (14M+ items)
- Fast barcode scanning
- Deep fitness tracker integrations
- Established community and recipe sharing
Cons
- Entirely calorie/macro focused
- No symptom or feeling tracking
- Data privacy concerns after 2018 breach
- Free tier is ad-heavy and cluttered
Best if: Your primary goal is calorie counting, hitting macros, or weight management with precise nutritional data.
2. Noom
Psychology-based weight loss coaching
Noom takes a different approach than most food trackers. Instead of just logging numbers, it wraps food tracking in a behavioral psychology program. Foods are categorized by color (green, yellow, red) based on calorie density. You get a personal coach, daily lessons about habits and mindset, and accountability features to keep you on track.
The evidence-based approach is genuinely interesting. Noom focuses on building long-term habits rather than just tracking calories for a few weeks. The onboarding quiz is well-designed, and the daily lessons teach you useful things about why you eat the way you do.
The big downside is cost. At roughly $70 per month, Noom is by far the most expensive option on this list. Coaching quality varies depending on who you're matched with. And under the hood, it's still a calorie-tracking app. If you're not trying to lose weight, or if you're trying to understand food sensitivities rather than reduce intake, Noom isn't the right tool.
Pros
- Evidence-based behavioral approach
- Personal coaching and accountability
- Teaches habits, not just tracking
- Excellent onboarding experience
Cons
- Very expensive ($70/mo)
- Coaching quality is inconsistent
- Still calorie-focused at its core
- Requires 15+ min daily time commitment
Best if: You want structured weight loss coaching with a behavioral psychology angle and you have the budget for it.
3. Cara Care
Medical-grade tracking for digestive disorders
Cara Care is built specifically for people with diagnosed digestive conditions like IBS, Crohn's, or SIBO. It tracks meals alongside symptoms (bloating, cramps, nausea), stool consistency using the Bristol scale, stress levels, and sleep quality. The app includes a FODMAP database, which is useful if your doctor has put you on a low-FODMAP elimination diet.
Where Cara Care shines is its medical partnerships. The app was developed in collaboration with gastroenterologists, and it generates reports you can bring to your doctor. If you're actively working with a GI specialist, this level of clinical detail is genuinely helpful.
The downside is that Cara Care feels clinical. The interface is functional but not inviting. It requires a cloud account, so your health data leaves your device. And it's narrowly focused on digestive symptoms. If your concern is energy levels or mood after eating (rather than specific GI symptoms), Cara Care tracks more than you need in some areas and less than you need in others.
Pros
- Designed with gastroenterologists
- FODMAP database built in
- Detailed symptom and stool tracking
- Generates reports for your doctor
Cons
- Clinical feel, not for casual use
- Requires cloud account (data leaves device)
- Complex interface with steep learning curve
- No energy or mood tracking
Best if: You have a diagnosed digestive condition like IBS and want medical-grade tracking to share with your GI doctor.
4. Yazio
Clean calorie tracking with fasting support
Yazio is a solid calorie and macro tracker with a noticeably cleaner interface than MyFitnessPal. It has a good food database (not as large as MFP, but sufficient for most users), barcode scanning, and nutrient breakdowns. Where Yazio differentiates itself is its built-in intermittent fasting timer. If you practice 16:8, 18:6, or other fasting protocols, having the timer integrated with your food log is convenient.
Yazio also offers meal plans and recipe suggestions based on your dietary goals, though most of these features are locked behind the Pro subscription. The app is popular in Europe and has strong support for European food products and brands.
Like MyFitnessPal, Yazio is entirely calorie-centric. There's no way to track how food makes you feel, no symptom logging, and no food sensitivity insights. If fasting is part of your routine and you want a cleaner interface than MyFitnessPal, Yazio is a good choice. If you're looking for anything beyond calories, it won't help.
Pros
- Clean, modern interface
- Integrated intermittent fasting timer
- Decent food database with barcode scanning
- Meal planning and recipe features
Cons
- Still calorie-focused, no feeling tracking
- Best features locked behind Pro
- Meal plans are generic
- No food sensitivity or symptom insights
Best if: You want calorie tracking with a cleaner interface than MyFitnessPal and you practice intermittent fasting.
5. mySymptoms Food Diary
The original food-symptom correlation tool
mySymptoms has been around since 2012, making it one of the oldest food sensitivity trackers available. It lets you log meals and track a long list of symptoms, then generates analysis reports that show potential links between specific foods and your symptoms. You can export PDF reports for your doctor, which is a useful feature if you're working with a healthcare provider to identify trigger foods.
The one-time purchase price of roughly $4 is refreshing in an era of monthly subscriptions. You pay once, you own it, and there's no premium tier to upsell you on.
The tradeoff is the interface. mySymptoms looks and feels like an app from 2015. Navigation is confusing, and there's a real learning curve before you can use it efficiently. The correlation analysis requires manual interpretation (the app highlights potential links, but you still need to figure out what they mean). The full-featured version is iOS only, with the Android version being more limited. If you can get past the dated design, the core functionality is solid for the price.
Pros
- Affordable one-time purchase ($3.99)
- Detailed symptom tracking options
- Generates PDF reports for doctors
- Proven track record since 2012
Cons
- Dated interface (looks like 2015)
- Steep learning curve
- Manual correlation interpretation needed
- Full version is iOS only
Best if: You want a proven, affordable food-symptom tracker and don't mind a dated interface. Great for generating reports to bring to your doctor.
6. Palate
Track how food makes you feel, not how much you eat
Palate takes a completely different approach. Instead of counting calories or tracking clinical symptoms, it focuses on three things: your energy, your mood, and your digestion. You log what you ate (free-text, no database searching), then check in later with how you feel on simple 1-5 scales. Over time, Palate's pattern engine analyzes your history and surfaces correlations automatically.
The insights are specific and actionable. Not "you might be sensitive to dairy" but "your energy drops 1.4 points on days you eat cheese" or "your digestion scores 40% higher on days with salmon." The app finds these patterns for you. You don't need to stare at spreadsheets or interpret charts.
Logging is fast. About 30 seconds for a meal, since you're typing what you ate rather than searching through a database. And everything stays on your device. No account, no cloud, no data leaving your phone. Period.
The tradeoffs: Palate is a new app, so the community is small. There's no barcode scanning (not needed for free-text logging, but some people prefer it). And it deliberately does not track calories or macros. If you need nutritional data, this isn't the app for you. Palate is for people who want to answer one specific question: how does food make me feel?
Pros
- Unique feelings-first approach (energy, mood, digestion)
- Automatic pattern detection, no manual analysis
- Fast 30-second logging
- 100% private: all data on device, no cloud, no account
- Clean, modern design
- Works fully offline
Cons
- New app, smaller community
- No barcode scanning
- No calorie or macro tracking
- Limited data history on free tier
Best if: You suspect certain foods are affecting your energy, mood, or digestion and you want an app that finds those patterns automatically, with zero data leaving your phone.
Full disclosure: we built Palate, so we're biased. But we also built it because we genuinely believe the question "how does food make me feel?" deserves its own dedicated tool. The other apps on this list are good at what they do. Palate exists for the people those apps don't serve.

Which App Should You Actually Use?
Here's the short version, organized by what you're trying to do.
Want to count calories and track macros? Go with MyFitnessPal. It has the biggest food database and the most integrations. Nothing else comes close for pure nutritional tracking.
Want structured weight loss coaching? Noom is the best option if you can afford $70/month and you're willing to commit to daily lessons. The behavioral psychology approach works for a lot of people.
Have a diagnosed digestive condition like IBS? Cara Care was built for exactly this. FODMAP database, detailed symptom tracking, doctor-ready reports. If your GI specialist told you to keep a food diary, this is the one.
Want calorie tracking with intermittent fasting? Yazio gives you a cleaner experience than MyFitnessPal with a solid built-in fasting timer. Good value at $6.99/month for Pro.
Want detailed food-symptom logs for your doctor? mySymptoms has been doing this since 2012. The interface is dated, but the one-time $3.99 price is hard to beat. Especially useful if you're actively working through an elimination diet with a healthcare provider.
Want to understand how food affects your energy, mood, and digestion? That's what we built Palate for. No calorie counting. No cloud accounts. Just a fast, private way to track meals and feelings, with automatic pattern detection that tells you which foods are helping and which ones are dragging you down.
There is no single "best" food diary app. The best one for you depends on what question you're trying to answer. A bodybuilder tracking protein needs a different tool than someone trying to figure out why they crash every afternoon. Pick the app that matches your actual goal, not the one with the most features.
Ready to track how food makes you feel?
Palate is the food diary that cares about your energy, mood, and digestion. Not your calories. 100% private.
