シンプルQRコード読み取り is a free Android application developed by maruju. The app aims to provide a simple and quick QR code scanning experience. It allows users to scan various types of QR codes such as URLs, email addresses, and phone numbers. Once the code is scanned, the app will automatically open the corresponding app such as a browser, email client, or dialer without any confirmation. The app uses the "QR Code Scanner" for scanning purposes, which needs to be installed beforehand.

The app's primary focus is to use the "QR Code Scanner" in a simple and straightforward way. The app does not have any settings for autofocus or scanning-related configurations. The app's display is in landscape mode, but it can scan codes in portrait mode as well. However, it is recommended to scan only reliable QR codes as the app does not have any confirmation prompts, and some codes may execute without confirmation. The app does not support scanning of phonebook or bookmark data.
