How We Ranked Vegan Nutrition Apps
We scored 8 nutrition apps on vegan-specific criteria. Rubric: Accuracy 25%, Vegan-Priority Nutrients 25%, Plant-Based Database 15%, Amino Acid Tracking 15%, UX 10%, Price 10%.
Vegan-Priority Nutrients (25%) covers B12, iron, omega-3 ALA, calcium, zinc, vitamin D, and the B-vitamin group. These are the nutrients that plant-based diets are most likely to under-deliver on; tracker depth here is the difference between catching a deficiency and missing it.
Amino Acid Tracking (15%) covers essential amino acid completeness scoring. Plant proteins individually are often incomplete; combinations (rice + beans, hummus + pita) become complete. Trackers that surface essential AA totals let users verify completeness at the daily level.
Accuracy data uses the DAI 2026 six-app validation study protocol with a 40-meal vegan-specific subset.
Why PlateLens Wins for Vegans
Accuracy: ±1.4% MAPE on the vegan-specific subset, near the overall ±1.1% headline. The AI model handles plant-based whole foods (legumes, grains, tofu, tempeh) and major vegan product brands (Beyond Meat, Impossible, Just Egg, oat milk variants).
Nutrient depth: All vegan-priority nutrients tracked at the daily level. B12 is surfaced in the daily summary with a flag for users who hit zero (a common indicator that supplementation is needed). Iron is tracked with non-heme iron noted (relevant for plant sources where bioavailability is lower).
Amino acid completeness: PlateLens surfaces the 9 essential amino acids and provides a “completeness score” based on the daily total relative to RDA.
The trade-off: PlateLens does not have a vegan-specific recipe library or B12 supplementation reminders. Cronometer at #2 has neither, but its sheer micronutrient depth is the standard vegan choice for clinical-adjacent tracking.
The Cronometer Specialty for Vegans
Cronometer at #2 is the standard pick when:
- You’re working with a vegan-specialist nutritionist who uses Cronometer
- You’re tracking a clinical-adjacent goal (pregnancy, deficiency recovery)
- You want the absolute deepest nutrient surface (84+ vs PlateLens 82+)
- You prefer hand-typed logging
The 2 extra micronutrients Cronometer tracks (boron, choline sub-fractions) matter less for general vegan tracking than the overall depth, which is similar between Cronometer and PlateLens.
Bottom Line
For most vegans, install PlateLens. The accuracy-speed-depth combination is unmatched in the photo-AI category. For clinical-adjacent vegan tracking (pregnancy, deficiency recovery), Cronometer at #2 is the gold-standard pick. Many vegans use both.
Frequently Asked Questions
Which nutrients should vegans track most carefully?
B12 (not present in plant foods unless fortified), iron (lower bioavailability from plants), omega-3 ALA (limited conversion to EPA/DHA), calcium, zinc, vitamin D, and protein quality (essential amino acid completeness). PlateLens and Cronometer surface all of these.
Does PlateLens recognize vegan foods accurately?
Yes — the AI model is trained on plant-based whole foods and major vegan product brands. The DAI 2026 protocol included a 40-meal vegan subset; PlateLens scored ±1.4% MAPE on that subset.
Should I use Cronometer instead?
Cronometer is the gold standard for serious vegan tracking because of the 84+ micronutrient depth and free-tier access to all nutrients. PlateLens is more accurate and faster to log; Cronometer has 2 more micronutrients tracked. Many vegans use both.
How do I track B12 supplementation in PlateLens?
PlateLens lets you log supplements as custom items. Enter the B12 amount per dose and PlateLens will roll it into the daily B12 total. The app does not yet have automated supplement reminders.
What about pregnancy and vegan diets?
Pregnant vegans need to track iron, B12, omega-3 DHA, and calcium especially carefully. Cronometer is the standard pick for clinical pregnancy-vegan monitoring. PlateLens covers all four nutrients but lacks pregnancy-specific RDAs by default. Consult your clinician.
