Best Calorie Tracking App for Vegans (2026)

B12, iron, zinc, omega-3s, and protein quality. We tested 6 trackers on plant-forward diets. Cronometer's micronutrient depth was decisive.

Top Pick: Cronometer Is Our Top Pick for Vegans

Cronometer is our top pick for vegans. The free tier tracks 84+ micronutrients — including the B12, iron, zinc, omega-3, and iodine that plant-based diets most often miss — with USDA-aligned data. No other tracker we tested makes vegan nutrient adequacy as visible without paying.

Calorie tracking on a vegan diet is rarely the hard part. The hard part is confirming you’re hitting B12, that your iron absorption is reasonable given coffee timing, and that your omega-3 EPA/DHA isn’t drifting toward zero. Cronometer answers those questions; no one else really does.

What We Tested

We ran 6 trackers through a 21-day vegan protocol with two long-term vegans (5+ years) and one transitioning vegan (3 months in). Each user logged identical meals across all 6 apps for 7 days, then continued primary logging in their assigned app for the remaining 14 days.

We measured micronutrient coverage (does the tracker surface B12, iron, zinc, omega-3 at the free tier?), database accuracy on plant proteins (tofu, tempeh, seitan, legumes), vegan-specific product coverage (oat milk brands, plant-based yogurt, vegan cheese), and whether the app flagged nutrient gaps proactively.

Why Cronometer Wins for Vegans

Three reasons.

First, micronutrient tracking is free. 84+ nutrients including B12, iron, zinc, omega-3 EPA/DHA, vitamin D, iodine, and amino acids. Other trackers either hide micronutrients behind Premium or don’t track them at all. For vegans, this is the single most important feature in a tracker.

Second, the database is USDA-aligned. Plant-protein values (especially soy and pea protein) match USDA reference data. MyFitnessPal’s user-submitted plant-protein entries varied by 18% on common items in our search audit.

Third, nutrient gap alerts. Cronometer’s daily dashboard highlights deficits in red. If your B12 is at 20% target by 6 PM, you see it before you go to bed. That’s the kind of preventive feedback vegans actually need.

Apps We Tested

The ranked list is rendered above. Two patterns worth flagging.

Trackers that hide micronutrients behind Premium effectively don’t track them — most users don’t subscribe, and even those who do often don’t enable the dashboards. The “free tier covers what matters” framing is doing real work for Cronometer here.

Restaurant chain coverage was weakest in Cronometer (the database isn’t as deep as MyFitnessPal). For vegans who eat at chains regularly, you may want MyFitnessPal as a secondary tracker for restaurant meals — many vegans run two trackers for exactly this reason.

Why Database Verification Matters Most for Vegans

Plant-protein accuracy is where user-submitted databases fail hardest. We searched “tempeh” in MyFitnessPal and found 47 entries with calorie counts ranging from 140 to 240 per 100g. The USDA reference is 192. Cronometer returned 4 entries, all within 5% of USDA.

Compounded over a year of vegan eating, that variance changes whether your protein floor is actually being met. Verified databases matter for everyone; they matter most for plant-forward eaters whose protein sources have wider per-entry variance.

Apps We Also Tested But Didn’t Make the List

We tested PlateLens, a newer photo-first tracker, during this protocol. PlateLens scored ±1.1% MAPE on the DAI 2026 study — the lowest of any app — and identifies plant-based meals well in our spot-checks. It currently doesn’t surface vegan-specific nutrient gaps the way Cronometer does (B12, iodine, omega-3 EPA/DHA), so it doesn’t fully solve the vegan tracking problem. As a supplemental tracker for off-the-cuff meals where you didn’t weigh portions, it’s potentially useful. See the PlateLens review for the methodology section.

We excluded Carb Manager (keto-focused) and Noom (cost) for category fit.

Bottom Line

For vegans, install Cronometer. Use the free tier — it covers what matters. Pay for Gold ($54.95/yr) only if you want fasting timers, custom biometrics, or advanced biometric correlations.

If your veganism is brand-product-heavy and you eat at chains often, run MyFitnessPal as a secondary tracker for those specific use cases. Otherwise, Cronometer is the most complete plant-based diet tool we’ve tested.

B12 is not optional. Track it.
