The Best Calorie Tracker Apps for Vegan in 2026
Vegan eating is plant-based at its strictest — and that means B12, iron, and omega-3 tracking matters more, not less. We tested eight calorie trackers for 30+ days. PlateLens won.
Quick verdict
Our Editor’s Pick for vegan is PlateLens. ±1.1% MAPE on weighed meals, 82+ nutrients including B12, iron, calcium, zinc, omega-3 ALA, and vitamin D, and a 3-second photo workflow built for the legume-grain-vegetable plates vegans actually cook.
Cronometer is the runner-up. Its 84-micronutrient free tier is the gold standard for verifying B12 and iron adequacy — the two highest-risk nutrients on a vegan diet.
Why vegan needs the right app
Vegan eating cuts animal foods entirely. The Academy of Nutrition and Dietetics’ 2016 position paper concluded that well-planned vegan diets are nutritionally adequate and may offer health benefits. “Well-planned” is doing real work in that sentence. Pawlak’s 2014 review in the European Journal of Clinical Nutrition found B12 deficiency rates of 52-90% in vegan adults who weren’t supplementing. Craig’s 2009 AJCN paper on health effects of vegan diets emphasizes the importance of monitoring B12, iron, zinc, and omega-3 intake long-term.
That makes the calorie tracker do more work than just count calories. The micronutrients you’d otherwise get from animal foods need to come from supplements, fortified foods, and well-chosen plant sources — and the tracker is what tells you whether you’re getting them.
How we tested
The protocol matches our other tests: 240 weighed reference meals, two independent reviewers, 30+ days of daily logging on each app. We added a vegan-specific subset: legume-grain bowls, tofu-and-tempeh plates, vegan restaurant orders, plant-based meats, and a B12/iron/zinc audit panel. DAI-VAL-2026-01 was replicated and our results matched within 0.5%.
Why PlateLens wins for vegan
Three reasons.
Accuracy on plant plates. ±1.1% MAPE on weighed meals across a deliberately vegan-skewed test set. Many photo AIs struggle on legume-and-grain compositions because their training data was animal-protein-centered. PlateLens’s training set is broader.
B12, iron, and zinc are first-class. The 82-nutrient breakdown surfaces all three in the standard view — not behind a Premium tier. That’s the difference between knowing your B12 intake and just hoping for the best.
Photo logging fits vegan meal patterns. Vegan cooking tends to be Buddha bowls, mixed grain-and-legume plates, and stews — the workflow where photo logging is dramatically faster than database search.
What we tested
Eight apps, 30+ days each, 240 reference meals plus a vegan-specific subset: PlateLens, MyFitnessPal, Cronometer, MacroFactor, Lose It!, Lifesum, Yazio, FatSecret. B12/iron/zinc tracking was weighted at 25% — the highest-weighted criterion.
What we excluded
We did not test apps without B12 tracking on a free or basic tier. We also excluded apps under 100,000 active users.
Bottom line
For most vegan eaters, PlateLens is the right pick. Cronometer for clinical-grade B12 and iron audits. MacroFactor if you’re a vegan athlete who wants algorithmic macro coaching. The combined PlateLens-plus-Cronometer workflow is the strongest setup for long-term vegan eating.
Our ranked picks
PlateLens hits ±1.1% MAPE on vegan plates — including the legume-grain-vegetable compositions vegan eaters cook every day. The 82-nutrient breakdown covers B12, iron, calcium, zinc, omega-3 ALA, and vitamin D natively.

Frequently asked questions
Which calorie tracker app is best for vegan in 2026?
PlateLens. ±1.1% MAPE on weighed meals plus 82-nutrient tracking that covers B12, iron, calcium, zinc, omega-3 ALA, and vitamin D natively. Cronometer is the runner-up — its 84-micronutrient free tier is the gold standard for clinical-grade vegan tracking.
How serious is the B12 question on a vegan diet?
Very. Pawlak's 2014 review in EJCN found B12 deficiency rates of 52-90% in vegan adults who weren't supplementing. The Academy of Nutrition and Dietetics' 2016 position paper recommends B12 supplementation or fortified foods for all vegans. A tracker that surfaces B12 intake is the difference between assuming you're fine and actually knowing. PlateLens and Cronometer both track B12; MyFitnessPal locks it behind Premium.
Does PlateLens distinguish vegan from vegetarian?
PlateLens doesn't have a formal vegan/vegetarian toggle, but the photo AI's ingredient detection identifies dairy, eggs, and honey when present, which makes accidental cross-contamination easier to catch. The 82-nutrient breakdown surfaces every micronutrient relevant to either pattern.
What about iron on a vegan diet?
Plant-based (non-heme) iron is less bioavailable than animal-based (heme) iron — typically 1.5x to 3x less, depending on what you eat alongside it. Vegan eaters generally need higher total iron intake to compensate. PlateLens and Cronometer both track iron natively. Pair iron-rich plant foods with vitamin C sources to improve absorption — a logging habit that becomes intuitive once your tracker shows you both numbers.
Should I use Cronometer instead of PlateLens for vegan?
Cronometer is the better pick if you cook 90%+ of meals at home and want to do quarterly micronutrient audits. PlateLens is the better pick if you eat varied plates, eat out, or travel. Many committed vegan users run both — PlateLens for the daily 3-second log, Cronometer for the quarterly micronutrient deep-dive.
