Welwa Features

Multi-member family profiles

Most scanner apps treat you as a single user. Welwa knows the whole household.

Add each family member with their own allergens and dietary needs. Every scan checks every member at once. The verdict tells you who it's safe for — and who it isn't.

Free: up to 3 family members
Premium: up to 6 family members
Premium Plus: unlimited family members

Sweep mode — beyond the barcode

The barcode database knows what the manufacturer told it. The ingredient panel knows what's actually in the product right now.

Welwa's sweep mode reads the entire panel — front, back, "may contain" warnings, certification stamps in the tiny print — and rolls them all into one verdict. Reformulations get caught the day they hit shelves.

Works on cylindrical packaging (cans, jars) and flat packaging (boxes, pouches). Multi-frame consensus and rotation detection mean Welwa reads what's actually printed — not what the lighting tried to obscure.

Allergen detection — free, forever

All 10 FDA Big-9 allergens, including fish, are detected on the free tier. We never paywall allergen detection. That's the floor.

• ✓ Peanuts
• ✓ Tree nuts
• ✓ Dairy
• ✓ Gluten
• ✓ Soy
• ✓ Eggs
• ✓ Shellfish
• ✓ Wheat
• ✓ Sesame
• ✓ Fish

Plus Vegan and Low-Sodium dietary filters in Free.

Religious + lifestyle dietary filters — Premium

Welwa surfaces certification marks the same way Naomi's grandmother read them: by recognizing the symbol on the package.

• ✓ Kosher (OU, OK, Star-K, COR, Earth Kosher, Chof-K)
• ✓ Halal (IFANCA, HFCE, HFA)
• ✓ Keto
• ✓ Sugar-Free
• ✓ GMO-Free (USDA Organic, Non-GMO Project Verified)

Premium does not make religious determinations. Welwa reports the certification body it found. You apply your own halachic, Islamic, or dietary standard.

Scan history that earns its keep

Free: last 30 days, searchable
Premium: unlimited history
Premium Plus: exportable allergen reports (PDF + CSV) for pediatricians, school nurses, and camp forms

Privacy — Airplane Mode

Welwa can run on USDA + Open Food Facts data alone, with no cloud calls. Turn on Airplane Mode in Settings → Privacy. Verdicts still work. Banner ads disappear. Your scan history stays on your phone.

What Welwa is not

Welwa is not a medical device. Welwa is not a religious authority. Welwa flags potential issues — it does not certify safety. Always read product labels. Consult medical professionals about allergies.
