The human memory is limited, especially in these days when there is so much information. So we all need to use some note taking software to help memorize, otherwise you will slowly forget a lot of things over time. But everyone has different needs and habits, so a large number of note taking tools with different characteristics have been created, such as Evernote, OneNote, Bear, ZoHo, Leanote, GitNote, SimpleNote, Boost Note, and Joplin.
