Free Calorie Tracker for iPhone: Every Option Ranked for 2026

The App Store has hundreds of calorie trackers, and nearly all of them claim to be free. In reality, most are free to download and then immediately start asking you to subscribe. The actual free experience ranges from genuinely usable to barely functional demo mode. If you own an iPhone and want to track calories without paying, this guide separates the apps that actually work for free from the ones that just use "free" as bait.

What "Free" Actually Means on the App Store

Apple requires that any app with in-app purchases be labeled accordingly, but the distinction between "free with optional upgrades" and "free trial that expires in 3 days" is not always clear from the listing. For this guide, "free" means you can use the core calorie tracking features indefinitely without paying. Apps that offer only a time-limited trial are excluded.

Best Free Calorie Trackers for iPhone, Ranked

1. Lose It (Free Tier) — Best Overall Free iPhone Experience

Lose It earns the top spot for iPhone users because its free tier is genuinely functional, the app is well-designed for iOS, and it includes features that competitors have paywalled.

What you get for free:

• Calorie and basic macro tracking (protein, carbs, fat)
• Barcode scanning (still free, unlike MFP)
• Food database with good coverage
• Snap It photo recognition (limited daily uses)
• Weight tracking and basic goal setting
• Clean, modern iOS interface
• Apple Health integration (writes calorie and weight data)

Apple ecosystem integration:

• Writes nutrition data to Apple Health
• Reads exercise data from Apple Health
• Home screen widget showing daily calories remaining
• iPhone keyboard shortcut for quick logging
• No native Apple Watch app on free tier

The limitations:

• Ads throughout the app (banner ads, occasional interstitials)
• Detailed nutrient tracking (fiber, sodium, vitamins) requires Premium
• Water tracking requires Premium
• Meal planning and patterns locked behind paywall
• Snap It photo recognition limited to a few scans per day
• No Apple Watch app on free tier
• Premium costs approximately USD 3.33 per month on annual billing

2. FatSecret (Free Tier) — Most Features for Free

FatSecret gives away more features on its free tier than almost any competitor. It is not the prettiest app on iOS, but if your priority is maximum functionality at zero cost, it is hard to beat.

What you get for free:

• Full food diary with calorie and macro tracking
• Barcode scanning with a large database
• Recipe creation and meal logging
• Exercise logging with calorie integration
• Diet calendar for reviewing past days
• Community forums
• Basic image recognition for food

Apple ecosystem integration:

• Apple Health integration (read and write)
• Home screen widget available
• Works on iPad as well
• No Apple Watch app

The limitations:

• Banner ads throughout the app
• The interface feels dated compared to Lose It or MFP
• Nutrient tracking beyond macros is limited on free
• No Apple Watch support
• Image recognition is basic compared to AI-powered options
• Some features feel buried in the interface

3. MyFitnessPal (Free Tier) — Large Database, Shrinking Free Features

MFP still has the largest food database in the space, which is its main selling point. The free tier has been progressively gutted, but it remains functional for basic calorie logging if you do not mind manual searching.

What you get for free:

• Basic calorie and macro tracking
• Access to the largest food database (user-submitted, accuracy varies)
• Community features and forums
• Basic exercise logging
• Recipe calculator

Apple ecosystem integration:

• Apple Health integration
• Home screen widget
• Apple Watch app (basic, shows remaining calories)
• Siri shortcuts for logging

The limitations:

• No barcode scanning on free tier (the most significant limitation)
• Heavy ads including fullscreen interstitials
• Nutrient details beyond macros require Premium
• Food verification and meal insights require Premium
• The free experience feels intentionally degraded
• USD 19.99 per month for Premium is the most expensive mainstream option

4. Cronometer (Free Tier) — Best Free Micronutrient Tracking on iPhone

If you care about more than just calories and macros, Cronometer is the standout free option. It tracks over 80 nutrients on its free tier, which no other free app comes close to.

What you get for free:

• Detailed micronutrient tracking (80+ nutrients including vitamins and minerals)
• Verified food database (more accurate than user-submitted databases)
• Barcode scanning
• Basic diary and targets
• Web access for desktop logging

Apple ecosystem integration:

• Apple Health integration
• Basic widget support
• No Apple Watch app on any tier

The limitations:

• Ads on the free tier (less aggressive than competitors)
• No custom recipes on free tier
• No fasting timer on free
• Limited reporting and trends
• No Apple Watch app even on paid tier
• The interface has a steeper learning curve
• Gold subscription costs approximately USD 4.99 per month

5. Apple Health (Free, Not a Tracker)

This needs to be addressed because "Apple Health calorie tracker" is a common search. Apple Health is a data aggregation platform, not a food tracking app. It can store nutrition data that other apps write to it, and it can display that data. But it does not have a food diary, a food database, barcode scanning, or any way to log what you eat.

What Apple Health actually does for nutrition:

• Displays calorie and nutrient data sent by third-party apps
• Aggregates data from multiple food tracking apps into one view
• Shows trends over time based on imported data
• Integrates with other health metrics (weight, activity, sleep)

What Apple Health does not do:

• No food logging or diary
• No food database or search
• No barcode scanning
• No meal tracking
• No calorie goals or recommendations

You need a separate food tracking app. Apple Health is the dashboard, not the tool.

6. Yazio (Free Tier) — Decent Features, Heavy Upselling

Yazio has a functional free tier for iPhone, but the upgrade prompts are more aggressive than any other app on this list.

What you get for free:

• Calorie and macro tracking
• Barcode scanning
• Food database access
• Basic goal setting

Apple ecosystem integration:

• Apple Health integration
• Widget support
• Apple Watch app (basic, paid tier only for full features)

The limitations:

• Very aggressive Premium upselling
• Fullscreen ads
• Many features locked behind Pro (approximately USD 6.99 per month)
• Meal planning, recipes, and detailed tracking all require payment
• The constant upgrade prompts make the free experience frustrating

iPhone-Specific Features That Matter

When choosing a calorie tracker on iPhone, these iOS-specific features can significantly affect your daily experience:

Apple Health Integration

Every app on this list integrates with Apple Health to some degree, but the depth varies. Basic integration means writing calorie totals. Deep integration means syncing individual nutrients, reading exercise calories from workouts, and pulling weight data from a connected scale.

App	Writes to Apple Health	Reads from Apple Health	Nutrients Synced
Lose It Free	Yes	Exercise, weight	Calories, macros
FatSecret Free	Yes	Exercise, weight	Calories, macros
MFP Free	Yes	Exercise, weight	Calories, macros
Cronometer Free	Yes	Exercise	80+ nutrients
Yazio Free	Yes	Exercise, weight	Calories, macros
Nutrola	Yes	Exercise, weight, more	100+ nutrients

Home Screen Widgets

Widgets let you see your daily calorie progress without opening the app. On free tiers, most apps offer at least a basic calorie remaining widget. More detailed widgets (macro breakdown, water intake, streak tracking) typically require paid versions.

Apple Watch Support

This is where free tiers get thin. Most calorie trackers either do not offer Apple Watch apps at all, or restrict them to paid subscribers. On the free tier, you are mostly limited to viewing your phone's notification on your watch.

App	Free Apple Watch App	Watch Logging	Watch Complications
Lose It Free	No	No	No
FatSecret Free	No	No	No
MFP Free	Yes (basic)	No	Basic
Cronometer Free	No	No	No
Yazio Free	No	No	No
Nutrola	Yes (full)	Yes	Yes

Siri and Shortcuts Integration

A few apps support Siri shortcuts for voice-based logging, though the experience is clunky compared to native voice recognition within an app. MFP has basic Siri shortcut support. Most other free options do not.

The iPhone User's Real Decision

For most iPhone users, the practical choice comes down to:

Maximum free features: FatSecret gives you the most for zero dollars. It is not pretty, but it works.

Best free user experience: Lose It has the cleanest free iPhone app. It feels like a real product, not a demo.

Best free micronutrient tracking: Cronometer if you want to track vitamins, minerals, and specific nutrients beyond just calories and macros.

Largest database: MFP, but without barcode scanning on free, the large database is harder to use quickly.

For EUR 2.50 Per Month: Nutrola on iPhone

Nutrola is not free, but at EUR 2.50 per month it costs less than most apps charge for their premium tiers, and it includes features that none of the free options offer.

What EUR 2.50 per month gets you on iPhone:

• AI photo recognition: photograph any meal and Nutrola identifies the food and estimates portions
• Voice logging: describe your meal in natural language and it gets logged instantly
• Barcode scanning with 1.8 million+ verified database
• 100+ nutrient tracking (more than even Cronometer's 80+)
• Full Apple Watch app with logging capability directly from your wrist
• Home screen widgets showing detailed progress
• Deep Apple Health integration syncing 100+ nutrients
• Recipe import from any URL
• Zero ads anywhere in the app
• 9 language support

The Apple Watch difference is notable. None of the free calorie trackers offer meaningful Apple Watch logging. With Nutrola, you can log meals, check your daily progress, and view nutrient breakdowns directly from your watch without pulling out your phone. For people who track consistently, wrist-level access removes a significant friction point.

FAQ

What is the best completely free calorie tracker for iPhone? For most people, Lose It's free tier offers the best balance of features and usability on iPhone. FatSecret is the better choice if you want maximum free features and do not mind a dated interface. Cronometer is best if micronutrient tracking matters to you.

Can I track calories on Apple Watch for free? Not meaningfully. MFP offers a basic Apple Watch app on its free tier that shows remaining calories, but you cannot log food from the watch. Full Apple Watch food logging requires a paid app.

Does Apple Health track calories automatically? Apple Health does not have a food diary or logging capability. It stores and displays calorie data that other apps send to it. You need a separate food tracking app to actually log your meals.

Which free calorie tracker has the best iPhone widgets? Most free tiers offer similar basic widgets showing calories remaining for the day. Lose It and MFP have slightly better-designed widgets. Detailed macro and nutrient widgets are typically premium features.

Is MyFitnessPal still worth using on iPhone without paying? MFP's free tier is significantly less functional than it used to be. Without barcode scanning, logging packaged food requires manual database searches. If you primarily eat unpackaged whole foods and already know your way around the database, it can still work. For most people, Lose It or FatSecret free is a better experience.

Can I use Siri to log calories? A few apps offer basic Siri shortcuts, but the experience is limited compared to in-app voice recognition. Nutrola's built-in voice logging is designed specifically for food and understands nutritional context in ways that generic Siri commands cannot.

What happens to my data if I switch between free calorie trackers? Most calorie trackers allow data export, but importing into a new app is often not straightforward. Apple Health can serve as a bridge since multiple apps can write to and read from it, but individual food entries do not transfer. Starting fresh with a new app usually means losing your food diary history from the old one.
