12 Best Free Calorie and Macro Trackers — No Subscription Needed

The subscription model has colonized nutrition tracking. What were once free utilities — a calorie diary, a food database, a barcode scanner — now sit behind monthly paywalls that range from US$5 to US$20. For users who track intermittently, who are learning whether tracking improves their eating habits before committing to a paid tool, or who simply can’t justify a recurring expense for a food diary, the landscape looks frustrating. Most “free” apps have stripped their free tiers to the point of uselessness, reserving database access, barcode scanning, or macro reporting for premium subscribers.

But there are genuinely capable free options. The key is understanding what “free” actually means for each app: some offer unlimited free access with no time restriction, some offer a full-featured free trial before requiring payment, and some offer a permanently free tier with meaningful functionality alongside a paid tier with advanced features. These are not equivalent, and a review that treats them as interchangeable is not doing the reader a useful service.

This list evaluates 12 trackers on the capabilities available to a free-tier user specifically: food database access, barcode scanning without a paywall, macro reporting (calories, protein, carbohydrate, fat) in the free tier, export options for free users, and whether the free tier has a time limit after which it expires. All evaluations reflect the free-tier state of each app as of 2026.

What to look for in a free tracker

Before the list, three criteria that determine whether a free tier is genuinely usable.

Macro visibility without payment. Some free tiers show calorie totals but require a subscription to see protein, carbohydrate, and fat breakdowns. A tracker that shows calories but hides macros is not a macro tracker — it’s a calorie counter with a marketing problem. The list below includes only trackers where full macro reporting (all four primary macros) is available without payment.

Barcode scanning without a scan limit. Several apps offer free barcode scanning but cap it at a number of scans per day (commonly 5–10) before requiring a subscription unlock. If barcode scanning is limited, the free tier is not a real substitute for a paid tracker for regular users.

No hard time expiry. A “free trial” that converts to a paid subscription after 7, 14, or 30 days is not a free tier. These are trials and are labeled as such in the entries below. True free tiers remain free indefinitely.

The 12 best free trackers

1. CalEye (free tier, unlimited)

CalEye’s free tier includes photo-based food recognition with USDA FoodData Central database backing, full macro reporting (calories, protein, carbohydrate, fat, and glycaemic load), and unlimited barcode scanning. The photo logging workflow — point camera at a plate, receive itemized breakdown — requires no subscription. Each food item in the log is linked to its database source, so free users can verify what data is behind their numbers.

The free tier does not include advanced micronutrient reporting (those nutrients beyond the primary macros) or the full historical trend analysis available on the paid plan. For users whose goal is calorie and macro tracking, the free tier is complete. Export: nutritional summary reports are available to free users in PDF format.

Barcode limit: None. Macro reporting: Full. Time limit: None — permanently free.

2. Cronometer (free tier, unlimited)

Cronometer’s free tier is arguably the most generous in the category for data depth. Full USDA-sourced macro and micronutrient reporting, over 80 tracked nutrients, no barcode scan limit, no time restriction. The interface is more data-dense than most and requires more deliberate food selection — you navigate to specific entries and confirm them rather than accepting the first result automatically — but for users who value accuracy, this is a feature rather than a bug.¹

The free tier does not include nutrient timing views (meal-level breakdown vs day-level), custom nutrient targets, or body metrics correlation. Those are Cronometer Gold features. For most users, the free tier covers everything clinically meaningful.

Barcode limit: None. Macro reporting: Full. Time limit: None — permanently free.

3. MyFitnessPal (free tier, limited)

MyFitnessPal’s free tier still includes calorie and macro logging, a large database, and barcode scanning. The limitations added after the transition to a subscription model include: some premium features like food analysis insights hidden behind paywall, ad-supported interface, and occasional prompts to upgrade. Core macro tracking — calories, protein, carbs, fat — is still free. The database is large but quality varies significantly; user-submitted entries with inaccurate data are common, and there is no reliable way to distinguish them from verified entries without manual cross-checking.²

Barcode limit: None (as of 2026). Macro reporting: Full. Time limit: None — permanently free with ads.

4. FatSecret (free tier, unlimited)

FatSecret offers completely free macro tracking with no premium tier at all — the app is free-to-use, monetized by advertising. Database coverage is broad, drawn from a mix of USDA-sourced entries and user submissions. The absence of a way to filter by data provenance is the main limitation: you cannot tell, from looking at an entry, whether its calorie and macro figures came from a laboratory measurement or from a user who estimated their own recipe. For casual tracking, this is acceptable. For users who need data they can trust for clinical or performance purposes, the uncertainty is a problem.

Barcode scanning is functional and unlimited. Export: the web interface allows diary export to CSV. The mobile app does not offer a direct export button on the free tier; export requires logging into the web version.

Barcode limit: None. Macro reporting: Full. Time limit: None — permanently free with ads.

5. Lose It (free tier, limited)

Lose It’s free tier includes calorie tracking and a calorie budget tool but limits macro reporting. Protein, carbohydrate, and fat breakdown is partially visible on the free tier — users can see their logged macros for individual meals but the daily summary macro breakdown requires the premium subscription in the 2026 version. This is a meaningful restriction for users who are specifically trying to hit protein targets or carbohydrate limits.

Barcode scanning is available on the free tier with no stated scan limit. Database coverage for US packaged goods is strong. For users whose only goal is monitoring calorie intake without macro targets, the free tier is functional. For macro tracking specifically, the free tier has meaningful gaps compared to the options above.

Barcode limit: None. Macro reporting: Partial (full daily macro breakdown requires premium). Time limit: None — permanently free with limitations.

6. Nutritionix Track (free tier, limited)

Nutritionix’s free tier includes calorie and macro tracking with access to its restaurant chain database — the strongest selling point for users who eat frequently at US chain restaurants. Barcode scanning is available on the free tier. The database for packaged goods and restaurant items is more accurate for restaurant meals than MyFitnessPal’s, because Nutritionix actively maintains partnerships with major chains and verifies their nutrition data.³

The free tier has no time limit but restricts some features (recipe builder, detailed historical trends) to the premium tier. For a user primarily logging chain restaurant meals, the free tier of Nutritionix is likely more accurate than the free tier of MyFitnessPal for that specific use case.

Barcode limit: None. Macro reporting: Full. Time limit: None — permanently free.

7. MyNetDiary (free tier, limited)

MyNetDiary’s free tier includes basic calorie and macro tracking with USDA-sourced database access. Barcode scanning is available free of charge. The interface feels dated compared to newer apps but is functional and reliable. Premium features — blood glucose integration, detailed micronutrient reports, meal plans — require a subscription, but the core tracking workflow is free.

Database quality for whole foods is good because the primary source is USDA. Packaged goods coverage varies by region; strong for US, moderate for UK and Canada, limited elsewhere.

Barcode limit: None. Macro reporting: Full. Time limit: None — permanently free with feature limitations.

8. Yazio (free tier, limited)

Yazio’s free tier includes calorie logging and macro totals with a food database that mixes USDA-sourced and user-submitted entries. The fasting timer, one of Yazio’s headline features, is available on the free tier — if intermittent fasting tracking is your primary use case alongside macro logging, this combination is useful. Barcode scanning is available free. The premium tier adds meal plans and more detailed nutrient reports.

European database coverage (Germany, Austria, UK) is meaningfully better than most US-centric trackers. For European users, Yazio’s free tier may offer better database accuracy for local packaged goods than MyFitnessPal’s free tier.

Barcode limit: None. Macro reporting: Full. Time limit: None — permanently free with feature limitations.

9. Lifesum (free tier, very limited)

Lifesum’s free tier is substantially limited — more so than most alternatives. Core calorie logging is free, but the macro breakdown requires the premium subscription in the 2026 configuration. Barcode scanning is available free but limited in some markets. Meal plans, recipe tracking, and dietary guidance are all premium-only.

For a true macro tracker, Lifesum’s free tier is not competitive with the options above. It earns a place on this list because its interface is among the cleanest available and users looking for a simple calorie log with good design may find the limited free tier sufficient for their use case.

Barcode limit: Limited by region. Macro reporting: Partial (premium required for full breakdown). Time limit: None.

10. Carb Manager (free tier, limited)

Carb Manager’s free tier includes net carb tracking, basic macro logging, and barcode scanning. The keto-native UI — ketosis probability score, net carb budget gauge — is available on the free tier. The free tier database is functional for common foods. Advanced features — detailed recipe builder, extensive restaurant database access, advanced reporting — require the premium plan.

For users specifically following a ketogenic diet and wanting net carb tracking as the primary metric, Carb Manager’s free tier is more purpose-fit than a generic tracker’s free tier, even if the raw feature count is lower than Cronometer or CalEye.

Barcode limit: None. Macro reporting: Full (including net carbs). Time limit: None — permanently free with feature limitations.

11. MacroFactor (free trial, converts to paid)

MacroFactor offers a free trial of its full-featured app for a limited period (typically 7–14 days) before requiring a subscription of approximately US$4.99/month. This is not a permanently free tier — it is listed here because the trial period is long enough to evaluate whether the adaptive calorie target algorithm is worth paying for.

The app is notably accurate for users whose metabolic rate diverges from textbook estimates, because its target adjustment algorithm is based on body weight trend data rather than static TDEE formulas. If you complete the trial and find the adaptive targeting valuable, the subscription price is competitive. If you need a permanently free option, MacroFactor is not it.

Barcode limit: None during trial. Macro reporting: Full during trial. Time limit: Trial converts to paid after 7–14 days.

12. Noom (free trial only, no free tier)

Noom is included here as a warning label rather than a recommendation. It markets itself aggressively with “free” messaging that leads to a trial that converts to a subscription. There is no permanently free tier — the app is a subscription service with a trial. For users who want a free calorie tracker, Noom is not an appropriate option. It is listed here because its marketing frequently appears in “best free tracker” searches, and the distinction between trial and free tier deserves explicit clarification.

Barcode limit: N/A — app requires subscription after trial. Macro reporting: Limited even in trial. Time limit: Trial converts to paid.

Barcode scan speed: what the benchmarks show

Most apps now scan a common barcode in under two seconds — speed differences between apps are modest. The more meaningful variable is hit rate and database accuracy: whether the returned result is the correct entry with verified macro data rather than a user-submitted approximation. In informal testing across 50 common US supermarket products, CalEye, MyFitnessPal, and Nutritionix all returned results on 47–49 items. For international products, CalEye had notably better coverage for Indian, Korean, and West African packaged goods than any other app tested.

Export features for free users

Export capability matters for users who share food logs with a dietitian, physician, or coach. Most apps restrict export to paid tiers, but several provide meaningful free export options.

Cronometer’s web interface allows free users to export diary data as CSV. This is the most functional free export available — the CSV includes date, food item, all macro and micronutrient values, and meal timing. CalEye generates PDF summary reports free of charge. FatSecret allows diary export via its web interface at no charge. MyFitnessPal restricted CSV export to premium subscribers in 2023; free users can access basic reports but not raw data export.

For users who see a registered dietitian regularly and want to share logs, Cronometer’s free CSV export or CalEye’s PDF summary report are the most practical free-tier options.

The recommendation

For a permanently free, full-featured macro tracker with verified database quality: Cronometer or CalEye, depending on whether you prefer manual entry with micronutrient depth (Cronometer) or photo-based logging with quick meal capture (CalEye). Both are free indefinitely, both track full macros, both use USDA-sourced data as the primary database, and neither caps barcode scanning.

For a free tracker for US chain restaurant meals: Nutritionix Track’s free tier has the most accurate restaurant database at no cost.

For a keto-specific free tracker: Carb Manager’s free tier includes net carb tracking and the keto-native interface without a subscription requirement.

For a European user prioritizing local packaged goods: Yazio’s free tier offers better regional database coverage than US-centric alternatives.
