Coming soon to Google Play

Every member

Per-member profiles let you check one product against your whole family in one scan.

Every meal

Big-9 allergens plus Vegan + Low-Sodium filters free. Religious and lifestyle filters unlock in Premium.

Every label

Sweep mode reads the entire ingredient panel — even the "may contain" lines most apps miss.

Built for households where every label matters

Welwa scans product barcodes and ingredient labels at the grocery store, flagging allergens and dietary needs for every person in your household in two seconds.

Whether you're managing a child's severe allergy, keeping a Kosher home, or tracking a doctor-prescribed diet — Welwa reads every label, every reformulation, for every family member you've added.

Three families — three different reasons

Severe-allergy households

One peanut, one missed label, one ER visit. Welwa catches reformulations the moment they hit shelves and flags every allergen on your kid's profile before you put the product in the cart.

Religious-verification households

Kosher and Halal certifications hide in 4-point gray ink on the back of the box. Welwa surfaces OU, Star-K, COR, IFANCA, HFA, and other trusted certifications in one scan — and pairs them with your child's dietary restrictions if you've added them.

Multi-restriction parents

Celiac in one kid, dairy allergy in another, low-sodium for a parent. Welwa runs every check against every family member at once. One scan, one verdict per person.
