Unda

About this app

Unda shows you what groceries cost at supermarkets across Aruba, so you can see where your shopping is cheapest before you leave the house.

SEARCH AND COMPARE
Search for a product or browse the aisles and see the price at every store that carries it, cheapest first, with when each price was last checked.

SCAN IN THE STORE
Point the camera at a barcode for prices on the spot. Is the shelf price different or missing? Add it in seconds.

YOUR SHOPPING LIST, PRICED
Save products to one or more lists and Unda tells you which store is cheapest for the whole list. Share a list with family or friends so they can add it to their own Unda.

CANASTA BASICO
Products on the government price-control list show a badge and the maximum price, so you can check the shelf.

STORE CARDS IN ONE PLACE
Keep your loyalty and membership cards in Unda's wallet and show the barcode at checkout.

HELP EACH OTHER SAVE
Prices come from the stores themselves and from shoppers like you. Reports are checked before they go live, and contributors earn points and achievements. Invite friends with your own link.

PRIVATE BY DESIGN
No sign-up needed and no ads. An account is optional and only keeps your lists and cards in sync between phones. Unda never sells your data. Location is used only with your permission, to pick the nearest store when you add a price.

Unda is made in Aruba by Dot 1 Technologies. Prices may differ from the shelf; always check in store.
