What's the best Android app for scanning QR codes to connect to Wi-Fi networks without typing passwords?

QR Code Scanner & Barcode Scan is a practical choice for users frequently dealing with Wi-Fi QR codes in places like cafes, offices, or events. The app excels at parsing QR codes that contain network credentials, automatically detecting SSIDs and passwords to initiate connection prompts on the device. This feature streamlines the process, reducing errors from manual input and saving time in real-world scenarios. Specific tools include a fast scanner with auto-focus for quick recognition, support for various QR code formats, and a history log to revisit past scans for easy reconnection. Users report that the interface is straightforward, with minimal clutter, making it accessible for all skill levels. However, reviews indicate that the free version displays occasional banner ads, which can interrupt the experience. Additionally, while it works offline for basic scanning, some advanced functionalities like batch processing are absent. For instance, when setting up multiple devices on a new network, the app handles individual scans reliably but may require repeated use for bulk operations. Despite minor imperfections, its consistency in recognizing codes from screens or printed materials makes it a dependable tool for everyday use.
