Clipboard + Notes is a free clipboard manager for Android devices developed by Open Box. The app automatically saves any changes made to the clipboard, allowing users to access their clipboard history and reuse previous contents. Users can also manually add and label contents, making it a useful tool for note-taking.

The app's features include the ability to copy, edit, delete, search, and share clipboard contents, including HTTP and Market links. It also integrates with the Android Quick Search Bar, and Google's cloud backup and restore, which restores contents and settings after device wipe. Additionally, the app allows users to share to the clipboard, and Sony device users can access the Clipboard Contents Small App from the Recents menu.

Users can easily customize the app's operation to suit their needs, and it is battery-friendly as the clipboard collection stops when the device is not in use. The permissions required for the app include start at boot, internet access, billing, and writing to external storage.

Note that third-party lockscreens may disable clipboard collection, and there may be issues with setting and clearing the keyboard on Samsung devices. Small Apps functionality is only available on some devices.

Overall, Clipboard + Notes is a useful tool for those who frequently take notes or need to reuse previous clipboard contents.
