The best calorie tracker app for iPhone in 2026 needs to work with Apple Health, have a solid food database, and not lock basic features behind a paywall. We tested six iOS calorie trackers and ranked them on how much you actually get for free, how fast daily logging is, and whether the app keeps you coming back.
1. NutriBalance — Best Free Calorie Tracker for iPhone
Platform: iOS, Android Price: Free (premium optional)
NutriBalance is the best free calorie tracker app for iPhone in 2026. The full feature set — barcode scanner, AI plate scanner, macro tracking, daily streaks, leaderboard, and weight tracker — is completely free on iOS. No paywalled core features, no trial period that expires.
Standout iOS features:
- Barcode scanner — scan any packaged food label instantly
- AI plate scanner — photograph your meal and the app identifies foods and logs them
- Full macros (protein, carbs, fat, fibre, sodium) free, no subscription
- Daily streaks and habit tracking to build consistency
- Friends leaderboard — compete on calorie tracking consistency
- Weight tracker with trend chart
- 14-day free trial of premium features
NutriBalance is available on the App Store — download it free here.
2. Cronometer — Best for Accurate Nutrition Data on iPhone
Platform: iOS, Android Price: Free / $9.99/month gold
Cronometer is the most nutritionally accurate calorie tracker on iPhone. It uses USDA-verified food data rather than user-submitted entries, tracks 80+ micronutrients alongside calories, and shows you exactly where you're hitting or missing daily targets for vitamins and minerals.
The free tier covers barcode scanning, full macros, and micronutrient tracking. Gold adds predictive logging and biometric integrations. For iPhone users who want to optimise nutritional completeness alongside calories, Cronometer is the most rigorous option available.
Best for: iOS users focused on micronutrient completeness and verified food data accuracy.
3. MyFitnessPal — Best Database, Still Good on iOS Free Tier
Platform: iOS, Android Price: Free / $19.99/month premium
MyFitnessPal's iOS free tier is meaningfully better than its Android free tier — barcode scanning is still available to free iOS users, unlike Android where it's been moved to premium. The database of 14M+ foods remains MFP's biggest advantage, particularly for international foods and restaurant dishes.
The premium plan at $19.99/month unlocks macro customisation, detailed reports, and social features. For iPhone users who eat at a wide range of restaurants and need the deepest food database, MFP's free iOS tier is competitive — but NutriBalance's AI scanner and gamification make it a better daily driver for most users.
Best for: iPhone users who prioritise food database depth over gamification.
4. Lose It! — Best Simple Calorie Budget App for iPhone
Platform: iOS, Android Price: Free / $39.99/year premium
Lose It! has been on the App Store since 2008 and remains one of the cleanest, fastest calorie counter apps on iPhone. The interface is minimal, logging is fast, and the daily calorie budget display is easy to understand at a glance. The weekly budget view — where you can spread your calories across the week rather than strictly per day — is a useful feature for flexible dieters.
Best for: iPhone users who want a clean, no-frills calorie budget tracker without gamification.
5. Lifesum — Best Design on iOS
Platform: iOS, Android Price: Free / $9.99/month premium
Lifesum has the best visual design of any calorie tracker on the App Store — clean card layouts, smooth animations, and well-designed meal visualisations. The free tier is limited (no macro goals, limited logging history) but the app is genuinely pleasant to use. Premium unlocks personalised meal plans, detailed macros, and recipes.
Best for: iOS users who prioritise a polished, visually appealing app and are willing to pay for premium.
6. MyNetDiary — Best iPhone App for Simplicity
Platform: iOS, Android Price: Free / $8.99/month premium
MyNetDiary strikes a balance between features and simplicity that works well on iPhone. The free tier includes barcode scanning, basic macros, and a clean food diary. The nutrition grade system gives you a quick summary of your eating quality without needing to drill into specific nutrients.
Best for: iPhone users who find MFP and Cronometer too complex and want a simpler, cleaner experience.

What to Look for in an iPhone Calorie Tracker
Apple Health integration: The best iOS calorie trackers sync with Apple Health so your calorie data is available across apps, Apple Watch, and the Health app. Check whether sync is two-way.
Widget support: iOS 17+ supports interactive widgets. A calorie tracker widget lets you log food or check your remaining calories directly from the iPhone home screen or Lock Screen.
Offline access: Your food log should be accessible even without an internet connection. Most apps store recent data locally; check whether you can log offline.
Siri Shortcuts: Some iOS calorie trackers support Siri for voice logging ("Hey Siri, log a banana"). Useful for hands-free logging while cooking.
