An enhanced version of HiMemo, an easy and convenient hierarchical memo app, is now available! For example, there is a surprising amount of information that has a hierarchical structure, such as information linked to regions and organizational charts. Normally, such information is recorded in bulleted list format in the memo app, but adding or editing information is surprisingly troublesome. Inadvertently, problems such as breaking the hierarchical relationship will occur. With HiMemo2, information can be recorded hierarchically with a simple operation like bulleted list format, and it is easy to add or modify. It is also possible to display a tree that gives a bird's-eye view of the whole, and to export information to other apps and SNS in plain text format or HTML format. Features of HiMemo2. - You can easily enter and manage data with a hierarchical structure. - Share data between multiple iPhones, iPads, Macs (sync with the same Apple ID). - You can browse the data on your Apple Watch. The following functions have been enhanced and improved from HiMemo. - Data is synchronized with HiMemo. - Linked with Apple Watch. You can browse the data on your Apple Watch. - The search function has been enhanced, and you can now search across memos. - The UI is simpler and easier to understand. Data will be inherited from HiMemo, so if you are using iOS 15 or later, we recommend migrating to HiMemo2.
