A nutrition tracker built for plant-based nutrients
Most calorie apps were designed around meat and dairy. VeggieOS tracks the nutrients that genuinely need attention on a vegan diet — B12, iron, calcium, omega-3, zinc, iodine, selenium and protein — and explains absorption instead of just counting.
- Plant-focused food database with fortified products included
- Weekly view, because nutrition averages out over days
- Absorption-aware guidance, not raw numbers alone
- Log from scans, recipes and plans in one tap
Short answer
The VeggieOS nutrition tracker logs plant-based meals and tracks the nutrients that matter on a vegan diet: protein, vitamin B12, iron, calcium, omega-3, zinc, iodine, selenium and vitamin D. It shows weekly rather than daily averages, explains absorption factors such as pairing iron with vitamin C, and lets you log meals directly from scans, converted recipes or your meal plan. It is free and has no premium tier.

Key takeaways
- Tracks the eight nutrients that actually need attention on a plant-based diet.
- Weekly averages avoid the false alarm of a single below-target day.
- Absorption matters: the tracker explains inhibitors and enhancers rather than showing bare totals.
- Logging is one tap from a scan, a converted recipe or a planned meal.
- B12 is treated as a supplement question, honestly and without hedging.
Plant-based eating is nutritionally sound, but it does shift where the attention needs to go. Fibre, folate, magnesium, vitamin C and antioxidants usually take care of themselves. B12 needs a supplement. Iron and zinc need absorption strategies. Iodine, omega-3 and vitamin D depend heavily on where you live and what you buy.
General calorie apps are poor at this. Their databases underrepresent fortified plant milks, tempeh, seitan and nutritional yeast, and they show a raw milligram number for iron without distinguishing haem from non-haem absorption. VeggieOS is built around the plant-based case: the right foods, the right nutrients and the context that makes the numbers meaningful.
How it works
- 1
Log a meal
Search the plant-focused food library, scan a barcode, log a converted recipe, or accept a planned meal in one tap.
- 2
See the week
A weekly dashboard shows protein and each key micronutrient as a range, not a single-day pass or fail.
- 3
Understand the gaps
Where something is low, you get the specific foods that fix it and the absorption tips that make them count.
- 4
Adjust the plan
Send the gap to the meal planner or coach and next week's meals compensate automatically.
- 5
Track trends
Charts show whether variety and key nutrients are improving over weeks and months.
Why people use it
The right nutrients
B12, iron, iodine, zinc, selenium, calcium and omega-3 — not just calories and macros.
Absorption context
Vitamin C with iron, tea and coffee timing, soaking and fermenting, and fat with fat-soluble vitamins.
Fortified foods included
Plant milks, yoghurts and cereals are represented with real fortification data.
Weekly perspective
Reduces obsessive daily tracking while still catching genuine shortfalls.
Connected to everything
Scans, recipes and plans all feed the log without retyping.
Reassuring for sceptics
Concrete data to show a doctor, a parent or yourself that the diet is working.
The nutrients worth watching
B12 is the only nutrient that cannot be reliably obtained from unfortified plant foods; a supplement or fortified foods are required, and the tracker says so plainly rather than implying that seaweed or mushrooms will do.
Iron from plants is non-haem and absorbs less efficiently, which is why pairing with vitamin C and separating tea and coffee from meals matters more than the raw milligram figure. Zinc behaves similarly, and soaking, sprouting and fermenting genuinely help.
Iodine varies enormously by country and salt type, omega-3 is best covered by ALA sources plus an algae-based EPA/DHA supplement, and vitamin D depends on latitude and season for everyone, not only vegans.
Protein without the panic
Protein is the most discussed and least problematic nutrient in plant-based eating. Legumes, soy foods, seitan, grains, nuts and seeds cover requirements comfortably when calories are adequate, and the old idea that proteins must be combined at every meal has long been superseded.
The tracker shows protein as a weekly range against your goal, highlights your best sources, and flags the genuine risk case: eating too little food overall, which is far more common than an amino-acid problem.
Tracking that does not take over your life
You can log at whatever resolution suits you. Some people log every meal for two weeks to learn their baseline and then stop; others log only dinners; others accept planned meals with one tap and never search for a food at all. The weekly view is designed so that partial logging is still useful.
Real situations it solves
New to plant-based
Confirm in week one that protein and iron are genuinely fine.
Low ferritin history
Watch iron intake with pairing tips and check whether the trend improves.
Pregnancy and family
Track the higher requirements carefully, alongside professional advice.
Athletes
Hit protein targets across training days without guessing.
Fatigue investigation
See whether B12, iron or simple under-eating is the plausible cause.
Doctor visits
Bring a weekly summary instead of a vague description of your diet.

Frequently asked questions
- Which nutrients does it track?
- Calories and macros plus protein, vitamin B12, iron, calcium, zinc, iodine, selenium, omega-3 and vitamin D.
- Do I need to log everything?
- No. Even logging a few days a week gives a useful picture, because the tracker averages across the week.
- Does it tell me to take supplements?
- It states the mainstream position that B12 supplementation is necessary on a vegan diet, and suggests discussing vitamin D and algae omega-3 with a clinician.
- Can I log a scanned product?
- Yes, a scan can be logged directly with its nutrition data.
- Is it suitable for weight goals?
- Yes, calorie and macro targets are supported, with a deliberately non-obsessive presentation.
- Is the food database vegan-only?
- It is plant-focused and includes fortified products, but non-vegan items can appear so that household members and label comparisons still work.
- Can I export my data?
- Yes, your logs are yours and can be exported.
- Is it free?
- Completely, including every nutrient and every chart.
