Hata Raku Diary Pro responds to requests from corporations, etc. that they want to use it jointly in a group, and allows each user in the group to collect and manage information on multiple IDs as a group while using different IDs. This is a functional version.

For example, in a corporation, it can be used for sharing history and managing people and time.
It is also useful in various situations for information sharing in unions and study groups.

* Pro version registration is required in addition to user registration to log in to the app. For details, please see the Hata Raku Diary website.
