Grid Note is an Android app developed by Sumi Interactive that offers a unique "Grid Layout" design to help you structure your thoughts. It comes with a lot of built-in note templates, such as SMART, Cornell Note, 5W1H, and more, to get you started. However, you can also feel free to replace those with your own inventions.

One of the most prominent features of Grid Note is its unique grid format, which allows for structured note-taking. Additionally, the app offers a template library, allowing you to organize your notes with notebooks and tags. The app also supports Markdown, which is great for formatting your notes. You can export your notes in various formats, including PDF, Markdown, and HTML. Grid Note can be used offline, and real-time sync is available with a premium account.
