For example, information that has a hierarchical structure, such as information linked to regions or division of organization, that is, information that has multiple children dangling from a parent and overlaps with grandchildren and grandchildren. Is unexpectedly large. Usually, such information is recorded in a memo application in bullet points, but adding and editing information is surprisingly troublesome, and there was a problem that the hierarchical relationship collapses if careless. With HiMemo, you can record information hierarchically with simple operations, and you can also add or modify. It is also possible to export to other apps and SNS in a tree view mode that gives a bird's eye view of the whole, or in plain text format or HTML format.
