How it works

Three seconds
between you and peace of mind.

No reading seven-syllable ingredients. No parenting forums at 2am. Point, read, decide.

01

Scan the barcode.

Our scanner works on crumpled boxes, gift shop shelves, and half-peeled travel bottles. If we can't read the code, type the name.

02

Get a clear verdict.

Safe, Caution, or Avoid — tailored to your child's age, allergies, and sensitivities. Every flag shows the why, sourced to real studies.

Safe
FOR LEO · 8 MONTHS
03

Swap if you want to.

Got a "Caution"? We'll show three alternatives your kid can actually use, from brands you can find without a specialty trip.

Weleda · Calendula Cream
Safe
Pipette · Baby Balm
Safe
Three verdicts. No jargon.

We translate 14-syllable
chemistry into yes, maybe, or skip.

Go ahead, use it.

Every ingredient clears our database for your child's age and allergy profile. No known concerns at typical use levels.

    Per-child safety profiles

    Two kids.
    Two different answers.

    Leo is eight months with eczema. His sister Maya is four and outgrew most of it. A product that's great for one may be wrong for the other — Welo knows, so you don't have to track it.

    The science behind the verdict

    Built on research,
    not wellness gossip.

    Every flag in the app shows why it fired. Grades come from publicly available safety data, then get personalized to your child's age and skin.

    WA GS UC AV

    A grade you can act on.

    Welo Approved, Generally Safe, Use Caution, or Avoid — not a 47-ingredient chemistry lecture.

    Per kid

    Same bottle, different answer.

    Age group and skin conditions change the grade. What is fine for a four-year-old may not be for an infant with eczema.

    Where the data comes from.

    • EWG Skin Deep
    • Open Beauty Facts
    • Public regulatory ingredient lists
    A note from the founder

    I built Welo so a parent can scan a bottle and see a clear grade — personalized to their kid's age and skin — instead of decoding an ingredient list in a store aisle.

    Frequently asked

    Questions we
    hear a lot.

    Is Welo free? +
    Yes. Scanning, search, saved products, and child profiles are free.

It unlocks offline scanning, unlimited search, offline Safe Swaps, background sync, and safety alerts. Terms of Use · Privacy Policy.
    Who decides what counts as "safe"? +
    Welo grades ingredients against publicly available safety data, including EWG Skin Deep and Open Beauty Facts, then personalizes the grade to the child's age group and skin conditions. Every flag in the app shows the reason.
    Do you take money from brands? +
    Grades are not sold. Buy links in the app may be affiliate links; they do not change a product's grade or swap ranking.
    What products can I scan? +
    Baby and toddler care, personal care (shampoo, lotion, sunscreen, deodorant), and other cosmetics on the package barcode. If a product is missing, type the name in search or report it from the product screen.
    What if the barcode doesn't scan? +
    Type the brand, product name, or barcode in search. Same result as scanning. You can also report a missing or wrong listing from the product screen.
    Is my data private? +
    You create an account to use Welo. Profiles, saved products, and scan history can sync to our servers so they follow you across devices. We do not sell personal information. Delete your account in Account → Settings. Privacy Policy.
    Where can I get it? +
    Welo is an iOS app. Questions: [email protected].
