Mapew

Stop shopping in the dark.

Have you ever reached the checkout without knowing how much you were going to pay? Forgotten how much you paid for a product the last time you bought it? Or wondered whether the store charged the same price shown on the shelf?

Mapew tracks your shopping in real time and helps you stay in control of your cart. As you shop, it creates a digital copy of your cart on your phone and shows you information you normally wouldn't know until later.

TRACK YOUR SHOPPING IN REAL TIME
See your cart total as you shop.
Scan barcodes or take photos of shelf price tags.
AI Price Tag Scanner: take a photo of a shelf label and Mapew automatically identifies the product name, price, and up to three price columns (regular, wholesale, and card prices).
Know exactly how much you'll pay before you reach the checkout.
Set a spending limit and track your budget in real time.
REMEMBER WHAT YOU PAID

When you scan a product, Mapew shows you:

How much you paid the last time you bought it.
Whether the price has gone up or down.
The neighborhood where that price was recorded.

This makes it easier to spot price increases and decide whether it's worth buying the product.

LEARN MORE ABOUT YOUR FOOD

When you scan food products, you can also see:

Nutri-Score.
Whether the product is ultra-processed.
Number of additives.
Allergens such as milk, gluten, and more.

You can also create a profile with the ingredients you want to avoid, such as lactose, gluten, sugar, or alcohol. Mapew will alert you whenever a product contains them.
