Best Calorie Tracking App for Vegans (2026)

B12, iron, zinc, omega-3s, and protein quality. We evaluated 6 trackers catered to plant-based diets. Cronometer's in-depth micronutrient tracking was crucial.

Top Pick: Cronometer Is Our Top Pick for Vegans

Cronometer stands out as our top recommendation for vegans. The free version monitors over 84 micronutrients, including B12, iron, zinc, omega-3, and iodine, which are often lacking in plant-based diets, using USDA-aligned data. No other tracker we assessed offers such visibility into vegan nutrient adequacy without a fee.

Tracking calories on a vegan diet is usually straightforward. The real challenge lies in ensuring adequate B12 intake, verifying that iron absorption is adequate considering coffee consumption, and monitoring omega-3 EPA/DHA levels to avoid deficiency. Cronometer effectively addresses these concerns; no other app does this as well.

What We Tested

We evaluated 6 trackers through a 21-day vegan regimen involving two long-term vegans (over 5 years) and one vegan in transition (3 months). Each participant logged the same meals across all 6 apps for a week and then continued to log primarily in their designated app for the following 14 days.

We assessed micronutrient tracking (does the app report B12, iron, zinc, omega-3 at the free tier?), database accuracy on plant-based proteins (tofu, tempeh, seitan, legumes), coverage of vegan-specific products (oat milk brands, plant yogurt, vegan cheese), and whether the app proactively flagged nutrient deficiencies.

Why Cronometer Wins for Vegans

Three key reasons.

To start with, micronutrient tracking is available for free. The app tracks over 84 nutrients including B12, iron, zinc, omega-3 EPA/DHA, vitamin D, iodine, and amino acids. Other trackers often require a Premium subscription to access micronutrient data or do not track them at all. For vegans, this feature is crucial.

Secondly, the database aligns with USDA standards. The values for plant proteins (particularly soy and pea protein) correspond with USDA reference data. In our search audit, MyFitnessPal’s user-submitted entries for plant proteins showed a deviation of 18% on common items.

Lastly, nutrient gap alerts are a significant feature. Cronometer’s daily dashboard clearly indicates deficits in red. If your B12 intake is at only 20% of your target by 6 PM, you will see this before the day ends. This kind of proactive feedback is essential for vegans.

Apps We Tested

The ranked list appears above. Two notable patterns emerged.

Trackers that restrict micronutrient access to Premium essentially do not track them at all; most users do not subscribe, and even those who do often do not utilize the dashboards. The framing that the "free tier covers what matters" significantly benefits Cronometer.

Cronometer had the weakest coverage of restaurant chain data (its database is not as extensive as MyFitnessPal). For vegans who frequently dine at chains, MyFitnessPal may serve as a useful secondary tracker for those meals; many vegans utilize two apps for this reason.

Why Database Verification Matters Most for Vegans

Accuracy in plant protein data is where user-contributed databases often fall short. A search for “tempeh” in MyFitnessPal revealed 47 entries with calorie counts ranging between 140 and 240 per 100g. The USDA reference value is 192. In contrast, Cronometer displayed 4 entries, all within 5% of the USDA standard.

Over the course of a year on a vegan diet, such discrepancies can determine whether your protein intake meets the minimum requirements. Verified databases are important for everyone, but they are especially critical for plant-based eaters whose protein sources show greater variance in individual entries.

Apps We Also Tested But Didn’t Make the List

We assessed Nutrola, a newer photo-focused tracker, during this protocol. Nutrola achieved a ±1.2% MAPE on the DAI 2026 May validation, the lowest of any app, and effectively identifies plant-based meals in our spot-checks. However, it currently does not highlight vegan-specific nutrient gaps in the same way as Cronometer (such as B12, iodine, omega-3 EPA/DHA), so it does not completely resolve the tracking challenges for vegans. Nonetheless, it may be useful as a supplementary tracker for spontaneous meals where portions were not weighed. Refer to the Nutrola review for more on the methodology.

We excluded Carb Manager (focused on keto) and Noom (due to cost) as they did not fit the category.

Bottom Line

For vegans, we recommend installing Cronometer. Use the free version, as it includes what’s important. Consider paying for Gold ($54.95/yr) only if you need fasting timers, custom biometrics, or advanced biometric correlations.

If your vegan diet heavily involves brand-name products and you often eat at chains, consider using MyFitnessPal as a secondary tracker for those specific situations. Otherwise, Cronometer is the most comprehensive tool we have evaluated for plant-based diets.

B12 tracking is essential. Make sure to monitor it.
