Sito grows with your child
The Allergen Ladder
4 months to 2 years
With a check-in after each one
Egg, peanut, milk, wheat, soy, sesame, tree nuts, fish and shellfish, one at a time: a small amount first, then at least once a week to keep it up. After each one we ask how it went, and if something happens, we note it and ask before adding it to your child's allergies.
Sito for Babies
Starting Solids
4 months to 4 years
The right cut for every age, from the first spoon
How to serve each of 583 foods at your child's age, from the first spoon to age 4, with choking hazards flagged until 4 and whole nuts until 5. For babies 4 to 11 months it adds the signs of readiness and a quick log for every taste and texture.
Sito for Babies
Log meals, track 18 nutrients
From 1 year
Five ways to log, not just calories
A nutrition tracker for kids, not an adult calorie counter. Snap the plate and we identify the food and estimate the portion, or scan a barcode, describe the meal, search, or tap a recent food. Iron, calcium, zinc, vitamin D, fiber and added sugars show against daily ranges set for your child's age.
Sito for Kids
Scan before you buy
From 1 year
A score out of 100, with the reasons
Scan a barcode in the grocery aisle and get a score from 0 to 100 built for kids, not adults, that adapts to your child's age. We tell you why: sugars, additives, ingredient quality.
How We Score
Your weekly report
From 1 year
What went well, what to focus on next
Every week we turn seven days of meals into a clear report: what is going well, the one thing to focus on next, and how each nutrient is trending.
Ask anything about them
Every age
Answers built around their age and meals
“Can she have honey yet?” “How do I get more iron into a lunchbox?” Ask any time and get answers built around your child's age and what they eat.
Watch them grow
Every age
WHO charts under 2, CDC charts from 2
Add height and weight and see where your child sits on the charts pediatricians use, with the range doctors expect drawn in: WHO charts under 2, CDC charts from 2.
A report for their doctor
Every age
One PDF before the checkup
Before a checkup, one PDF with growth, nutrients, a meal diary and the allergens your child has tried; the sections follow their age. We make it on your phone, and nothing is sent until you share it.
Every child, both parents
Every age
One account for the whole family
Each child gets their own profile and their own targets. Invite the other parent with a code: you both log meals and see the same kids, and nobody has to text about lunch.
Frequently Asked Questions
What is Sito and how is it different from adult calorie trackers?
Sito is a nutrition app and food tracker for kids, toddlers and babies, built around your child's age. Adult apps count calories to help you lose weight. A growing child has the opposite problem, so Sito counts the things they need instead: iron, calcium, zinc, fiber, vitamin D. It also changes with your child's age: Starting Solids and the Allergen Ladder for a baby, how to serve 583 foods until age 4, and a score for packaged food worked out for your child's age.
Is Sito for babies too?
Yes. Babies 4 to 11 months get Starting Solids: the signs of readiness, how to serve each first food, and a quick log for every taste and texture, plus the Allergen Ladder. Full nutrition tracking opens at 12 months. At every age there are growth charts, answers to your questions and a report for your child's doctor.
What is the Allergen Ladder?
It walks you through 9 common allergens, one at a time: egg, peanut, milk, wheat, soy, sesame, tree nuts, fish and shellfish. After each one it asks how it went. If something happens, we note it and ask before adding it to your child's allergies. Every card follows public health guidance from the AAP, CDC and WHO.
How does Sito show how to cut and serve food?
Each of 583 foods shows the right shape and size for your child's age, from mashed to strips to quartered. Choking hazards are flagged until age 4, whole nuts until 5. When you log a meal, a short line reminds you how to serve the foods that still need it.
How does Sito make logging food easier for busy parents?
Five ways, and you use whichever is fastest at the time. Photograph the plate, scan a barcode, describe the meal, search our database, or tap a food from last week. We work out the portion and the nutrition.
My child is a picky eater. Can Sito help?
Ask our assistant. It knows what your child has actually eaten this week, so when you ask how to get fiber into someone who refuses vegetables, the answer is about your child rather than about children in general.
Can I track nutrition for multiple children in one app?
Yes. Each child gets their own profile and their own targets, built from their age, height and weight. A two-year-old and an eight-year-old need very different things, and Sito treats them that way.
What does scanning a food actually tell me?
A number from 0 to 100, and a word for how often it belongs in their week: everyday, most days, sometimes, once in a while, or rarely. Under it we show what drove the number, in plain language. Additives, added sugar, sodium, how processed it is. We publish the whole method, every weight and every threshold, and every additive we score, with the research behind it.
Can I share Sito with my child's doctor?
Yes. Before a checkup, make one PDF with growth, nutrients, a meal diary and the allergens your child has tried, and share it or print it. The sections follow your child's age, and the report comes in English, Spanish, French, German, Italian or Dutch.
Can both parents use one Sito account?
Yes. Generate a code in your profile and it signs your partner in to the same account. Same children, same logs, same subscription, nothing extra to pay. You can end it any time from Settings.
How much does Sito cost?
Free to download, with a free trial. A subscription opens the whole app, and the current price is shown there. It is on iOS and Android.
