HiMemo

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.

You can write your own memo to each mp3 file in the cloud shared by your members, and share it via e-mail. Notes can be shared for a single song or for a folder. This is a great way to communicate with your band members, or with a video director or producer in the middle of a shoot, without interrupting their time. You can also jot down notes on touring equipment and ideas while listening to mp3s in your spare time.
