Short answer: Cronometer. Its free tier already tracks up to 95 nutrients against a verified food database. MyNetDiary says up to 108 nutrient fields on USDA and NCC sources. SnapCalorie claims 100+ micronutrients from a plate photo. A food log is intake, not a blood test.

How this list was made

Four questions, answered only from each app’s own website, help center, or App Store listing on October 10, 2026:

Do its own pages name a micronutrient panel, a nutrient count, or named vitamins and minerals?
Is there a live iPhone listing?
Is the log a verified diary, a plate photo, or both?
What does it cost where the provider states a price and a billing period?

Six apps meet that bar. Cal AI’s website and App Store listing name calories, protein, carbs, and fat. We found no vitamin or mineral claim there. We did not weigh meals or draw blood, so nothing here is an accuracy ranking or a medical ranking.

The six apps

1. Cronometer: best verified micronutrient diary

Cronometer’s Gold page, read October 10, 2026, lists tracking up to 95 nutrients and compounds on the free tier, with a barcode scanner, custom micronutrient targets, and a database of over 1 million lab-analyzed or verified foods. Photo Log is Gold only ($10.99 a month or $59.99 a year). The photo is a search into NCCDB and CFCD. You still add oil, butter, and missed extras. Stay here if the vitamin number has to come from a verified entry you will edit. NutriCam vs Cronometer. Other photo-first options if the diary is the problem: Cronometer alternatives.

2. MyNetDiary: most nutrient fields on its own pages

MyNetDiary’s free calorie tracker page, read October 10, 2026, says you can track up to 108 nutrients per food entry free, including vitamins, minerals, omega fatty acids, and amino acids, from USDA and NCC. A support article lists those 108 fields. Meal Scan photo logging sits on Premium. The about page that day lists Premium at $8.99 a month or $59.99 a year. A versions article still describes the free app as calories, three macros, and five nutrients. We quote the 108 figure from the free calorie tracker page. We did not sit in the free diary to count which nutrients it actually shows.

3. SnapCalorie: best standing free photo log

SnapCalorie’s App Store listing, read October 10, 2026, claims 100+ micronutrients including vitamins, minerals, and amino acids from USDA-backed foods. Its FAQ says the app is free for up to 3 AI logs a day, and that oils when you eat out are an educated guess. Premium is $19.99 a month or $149 a year on the U.S. App Store that day. It is on iPhone and Android. A claimed count from a photo is not a verified diary entry. Free photo logs: free calorie trackers with photo logging.

4. Micron: best named 29-nutrient photo card

Micron’s tracker page, read October 10, 2026, lists 29 nutrients including iron, magnesium, vitamin D, and vitamin B12. The site says you photograph a meal, scan a barcode, or search, then compare intake with personalized targets. Its FAQ says to barcode packaged food for the amounts on the label, to treat a restaurant photo as an overview, and that nothing replaces a blood test for an exact level. The FAQ also says micronutrient tracking is available from the first meal. The U.S. App Store listing that day says iPhone only and lists Premium Monthly $8.99 and Premium Yearly $34.99 to $49.99. The site also links Google Play.

5. MacroFactor: best if you also want weekly calorie targets

MacroFactor’s vs Cal AI page, read October 10, 2026, lists Iron and Vitamin B12 among 54 trackable items. Its micronutrient tracking article says US labels must report iron and usually omit B12, so you should log common foods, not barcodes, when the vitamin number matters. The App Store listing that day names a food tracker for macros and micronutrients, a 7-day trial, then $11.99 a month or $71.99 a year, with no free tier. Coaching adjusts calorie and macro targets. It does not name dinner. Other photo-log options if the algorithm is the problem: MacroFactor alternatives.

6. NutriCam: best for “what should I eat next?” on iPhone

NutriCam is our app, and it is iPhone only. The App Store listing names iron, vitamin B12, iodine, and magnesium. Photograph a meal or say what you ate, confirm the estimate, and see calories, macros, and vitamins and minerals. Then ask what to eat next from today’s log, targets, workouts, and Apple Health sleep when connected. Skip it if you need Android or a verified food database. What the app is: what is NutriCam. How the next-meal answer works: what should I eat next. Other photo apps, by job: best AI calorie tracker apps.

A food log is not a blood test

An app adds the milligrams you logged. It does not know what you absorbed.

Cronometer’s Data Confidence article, read October 10, 2026, says branded foods often carry only the roughly 15 nutrients the label reports. Magnesium can read low because the barcode never had it, not because the food lacked it. Pick NCCDB or generic entries when the vitamin number is the point. MacroFactor’s micronutrient article says the same for B12.

A camera cannot see iron or B12. Oil, sauce, fortification, and portion weight stay invisible. Cronometer Photo Log maps the picture onto NCCDB after you review it. Micron’s FAQ, read October 10, 2026, says a barcode beats a photo, absorption varies per person, and a blood test is the exact level. None of these apps is a medical device. They do not diagnose a deficiency. Confirm foods and portions. See a clinician if you need medical nutrition. Photo vitamin logs: which app tracks micronutrients from a photo. Iron and B12 specifically: best app to track iron and B12 on iPhone. Kitchen tests of photo calorie apps ran low: how accurate are AI photo calorie counting apps.

No app can measure a meal from a photo. A picture cannot show oil, sauces, hidden ingredients, or portion weight. Every number from every app on this page is an estimate until you correct the foods and portions. We have not run an accuracy test across these apps, so this page makes no accuracy ranking.

Log the foods you already ate, then read vitamins and minerals against a verified diary entry if that number has to hold. NutriCam is an iPhone advisor: photograph a meal or say what you ate, confirm the estimate, and see vitamins and minerals such as iron, B12, magnesium, and iodine. It is not a blood test, not a medical device, and not on Android.
