The app has a simple and user-friendly interface, making it easy to use for anyone. WiFi Barcode is a great tool for those who frequently share their WiFi information with others, as it eliminates the need to manually enter the information. However, the app does not have any additional features beyond this function.

Overall, WiFi Barcode is a useful app for those who need to share their WiFi configuration frequently. The app is free to use and does not require any additional permissions. If you encounter any issues with the app, the developer encourages users to report them on the app's website, as leaving negative comments on the market will not help to improve the app.
