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 verdict cites its sources. Every ingredient is scored against pediatric dermatology literature, regulatory databases, and three independent reviewers.

    From the obvious ones to the ones that hide behind a generic word like "parfum." We unpack blends down to their disclosed components.

    A note from our founder

    When my daughter was six weeks old, I stood in a pharmacy aisle holding a bottle of baby wash, reading an ingredient list I didn't understand, while she cried in the carrier. I built Welo so no other parent has to be their own chemistry student at 9pm on a Tuesday.

    Frequently asked

    Questions we
    hear a lot.

    Is Welo free? +
    Scanning, verdicts, and one child profile are free forever. Welo Pro ($4.99/mo) adds unlimited profiles, ingredient deep-dives, and our curated safer-swap marketplace.
    Who decides what counts as "safe"? +
    A panel of four board-certified pediatric dermatologists and allergists sets our thresholds, which are then cross-referenced against EWG, FDA, and peer-reviewed pediatric literature. Every flag links back to its sources.
    Do you take money from brands? +
    No. Welo doesn't accept paid placements, affiliate commissions that influence rankings, or brand sponsorship of verdicts. Our swap recommendations are ranked purely by profile match.
    What products can I scan? +
    Baby & toddler care, personal care (shampoo, lotion, sunscreen, deodorant), and prenatal/postpartum products. We add roughly 400 new SKUs a week and are expanding into household cleaners next.
    What if the barcode doesn't scan? +
    Type the brand and product name. If we don't have it, submit a photo of the label — our team reviews every submission within 48 hours and emails you the verdict.
    Is my data private? +
    Scans are stored on-device by default. Profiles never leave our servers in identifiable form. We don't sell data, full stop. Read our privacy principles for the long version.
    When does it launch? +
