お買物アプリ is an Android app developed by 株式会社マクロミル. It is a free lifestyle app that allows users to scan the barcodes of purchased items and manage their shopping activities.

With お買物アプリ, users who are part of the shopping monitor program operated by Macromill can easily scan the barcodes of products they have purchased or received as gifts and enter the product information. This app provides the convenience of scanning barcodes anytime and anywhere, whether during commuting, studying, or doing household chores.

The key features of お買物アプリ include barcode scanning functionality, customizable settings for vibration, scan sound, and continuous scanning, as well as a light setting for scanning in dark places. Users can also check their activity status on the app's activity calendar and enable automatic login to the app.

The shopping monitor program allows participants to input and send information about the products they have purchased or received. This data is statistically processed to help with the development of new products, improvement of existing products, and market analysis.

To participate in the shopping monitor program, users need to register with Macro Mill Monitor and respond to the "shopping monitor recruitment" survey sent by Macro Mill. Only those selected will be able to join as shopping monitors.

Please note that the app is only available for shopping monitors and cannot be used by individuals who have borrowed the device. Additionally, users are responsible for any data charges incurred for downloading, updating, and configuring the app.
