DecoLu is a notebook app for Android that offers various features such as calendars, memos, to-do lists, and sticky notes, along with a canvas diary that can be freely decorated with a free layout. What sets DecoLu apart from other notebook apps is its various deco functions that allow users to decorate their notes with stickers, stamps, and other decorative elements.

However, it is important to note that DecoLu has ended its service on Tuesday, November 16, 2021, at 15:00. The offline version of the app will be available for a limited time until December 31, 2021, after which it will no longer be possible to update or reinstall the app. While the offline version can be used for the time being, it may not be compatible with future OS updates, and data cannot be transferred to another device.

Overall, DecoLu is a fun and creative notebook app for those who enjoy decorating their notes. However, with the end of its service and limited availability of the offline version, users may need to consider alternative calendar apps for future schedule management.
