Lnote is a free note-taking app developed by HW for Android devices. It is a simple and easy-to-use app that allows you to take notes on the go. With the Android 8.0 Oreo update, notes cannot be displayed on the lock screen due to Android OS specification changes. Instead, Lnote displays a note as a notification.

To view a note on the lock screen, you need to enter the note in the app. Once you do that, the note will appear on the lock screen. You can choose to hide the note by shaking the device from side to side. You can also unlock the screen as the note is displayed.

Lnote is a great app for those who need to take notes frequently and want a simple and easy-to-use app. Although it doesn't have many features, it serves its purpose well. Overall, Lnote is a good choice for anyone looking for a reliable note-taking app on their Android device.
