For tracking what your child eats against targets for their age, the best kids nutrition app in 2026 is Sito, the app we build. For every other app we read its App Store and Google Play listings, pricing pages and terms on 14 September 2026.

The best kids nutrition app depends on your child's stage.

TL;DR
  • For tracking what a child eats against age-based targets: Sito (ours).
  • For starting solids: Sito, from 4 months, with the signs of readiness, how to serve 583 foods at your baby's age and the Allergen Ladder for 9 common allergens.
  • MyFitnessPal (18+), Cal AI (13+) and Cronometer (not for under 13) are not built for children.

The ranked apps side by side

"Not mentioned" means the listing does not say, not that the app lacks it.

The 6 best kids nutrition apps, ranked

1. Sito: from first tastes to daily targets

From 4 months, Starting Solids shows how to serve 583 foods at your baby's age, and how every taste went. The Allergen Ladder takes 9 common allergens one by one until age 2, and how to serve stays until age 4.

From 12 months, Sito tracks 18 nutrients and sets daily ranges from your child's age, weight, height, activity and goal, including calories, protein, fiber, added sugars, sodium, iron and calcium, and vitamin D. You can also work out your child's daily calories with our kids calorie calculator. If a doctor or dietitian gave you a number, you can enter it instead.

  • Take a photo and we identify the food and estimate the portion. You can also scan a barcode, search, or type what your child ate.
  • Sito sets calorie targets, and the goal can be gain weight, stay fit or lose weight. Under age 5 we never propose lose weight and never lower calories for it, and under age 2 no goal changes calories.
  • Every child gets their own profile, and a partner can join with a 6-digit code.
  • Milk and vitamins: breastfeeds and bottles from birth to 2 years, with your formula picked by name, and vitamins at every age. From 12 months, bottles and vitamin doses count in the day's nutrients, iron and vitamin D included.
  • Barcodes get a 0 to 100 score from the label, stricter on flagged additives for children under 6, with a warning when a product matches your child's allergies.

It works on iOS and Android.

2. Solid Starts: a guide for starting solids

Solid Starts is built around its First Foods Database, which shows how to "safely introduce 400+ foods to baby", with choking and allergen guidance and how to cut and serve each food by age (App Store). Its log records foods tried and reactions, which you can download for doctors and caregivers. Its listing describes no daily nutrient targets, and its terms require you to be at least 13 to register on its website.

3. GrowwW: doctor-guided weaning

GrowwW says it was "developed with paediatricians" and follows WHO, ESPGHAN, AAP and German guidance (App Store). It offers a guided allergen program, a food library "with amount, form and safety by age", recipes, and a weekly check on iron, healthy fats, vitamin D and iodine with "No counting". It personalizes by age to the month, feeding approach, allergies and premature birth. Its terms say it is "intended for parents and guardians" and users must be at least 18.

4. Cronometer: detailed nutrients, adult targets

Cronometer is an adult nutrient tracker whose listing pitches it for "weight loss, muscle gain" (App Store). The listing doesn't mention child profiles, and its terms say it is "not intended for and should not be used by Children under the age of 13".

5. Yuka: a food scanner, not a tracker

Yuka scores food on "nutritional quality, presence of additives and organic aspect" (App Store). The listing describes no adjustment for a child's age. More in Yuka for kids and Yuka alternatives for parents. For scanners side by side, see the best food scanner apps.

6. Adult calorie apps, and why they don't fit children

MyFitnessPal

MyFitnessPal lets you set goals for "weight loss, gain, maintenance, or performance" (App Store). Its terms say: "You must be at least 18 years old to use the Services." For a child's weight, see what pediatricians suggest instead of a weight loss app for kids.

Cal AI

Cal AI is a photo calorie tracker whose App Store listing is framed around getting "your dream body" and says food scanning results require a subscription. MyFitnessPal says it has acquired Cal AI. Its terms require users to be at least 13, with a parent's consent and supervision from 13 to 17. See Cal AI for kids and calorie trackers for kids.

Other apps parents find when they search

  • All Done (iPhone): a typed log for babies and children, subscription only.
  • NurtureAI (iPhone, iPad): child profiles; scanning needs a subscription.
  • KidMeal AI (iPhone): photo and barcode scans with child profiles.
  • Little Joys (iPhone): a kids telehealth app and shop with pediatric consultations and a diet chart, not a food log.
  • KidScan (iPhone, iPad): checks baby product ingredient lists for "potential toxicity"; it is not a nutrition tracker.

What is the best app for starting solids?

Sito, from 4 months. The home screen becomes Starting Solids, with the signs of readiness and how to serve 583 foods at your baby's age. A quick log keeps every taste, its texture and how it went. The Allergen Ladder takes 9 common allergens one at a time, with a check-in after each.

Under 12 months there is nothing to count. Sito keeps what your baby has tried, how each food went, the allergens they have met and their growth. It puts them in a report for the doctor. More in our Solid Starts alternative guide.

What is the best nutrition app for toddlers?

  • What your toddler eats each day, against targets for their age: Sito (ours), from 12 months, including whether a picky eater is getting enough.
  • Starting solids and how to serve: Sito. Until age 4, each of 583 foods shows the right shape and size for your child's age. The Allergen Ladder stays open until age 2.
  • A log you write in words: Sito takes a typed description too, from 12 months.

Nemours KidsHealth says kids 12 to 24 months old "should drink whole milk to help provide the dietary fats they need for normal growth and brain development." The Dietary Guidelines for Americans, 2020-2025 named calcium, potassium, dietary fiber and vitamin D as nutrients of public health concern (ODPHP), and Sito tracks all four.

FAQ

Can kids use MyFitnessPal?

Not by its terms, which require users to be 18 or older. Cal AI is 13+, and 13 to 17 year olds need a parent's consent and supervision. Cronometer is not for children under 13. More in MyFitnessPal for kids.

Does Yuka work for kids?

Yuka scores food on nutritional quality, additives and organic status, and its listing describes no adjustment for a child's age (App Store). See Yuka for kids.

Can you track more than one child?

Sito: yes. Every child gets their own profile, with their own targets from 12 months, and a partner can log from their own phone. The listings for GrowwW, Solid Starts, Cronometer, Cal AI and MyFitnessPal don't mention it.

Can you log a portion without weighing it?

Sito: yes. From 12 months, tap one of the food's portions, or type the amount your own way, like "3 halves", and our AI picks the matching portion.

Is there a nutrition app for babies?

Yes. From 4 months, Sito's Starting Solids shows the signs of readiness, how to serve each first food at your baby's age, a quick log for every taste and texture, and the Allergen Ladder for 9 common allergens. There is nothing to count until 12 months, when the full app opens with meals from a photo and 18 nutrients. From then on, what you log in Starting Solids counts in the day's meals.
