価格比較　価格なび

"Kakaku Navi" is a shopping assistance app that allows you to compare prices from online shopping sites such as Rakuten Market and Yahoo! Shopping simply by scanning the product barcode.

Beyond comparing prices, you can also scan barcodes of products you're interested in to check reviews or use it as a memo pad.

It's the perfect shopping companion!


● Compare prices using "effective price" including points
Even if the displayed price is low, the ranking may change once points are added.

Kakaku Navi allows you to sort by the "effective price," which is the price after deducting the points you are expected to receive.

Simply register 23 items in the app's "Point Condition Settings," including your Rakuten Card type, Rakuten Member Rank, Rakuten Mobile, Rakuten Bank, Yahoo! Shopping payment method, LYP Premium membership, LINE integration, and other Rakuten Group services.
