iDailyDiary has been designed around a simple page-for-a-day diary. Your diary can contain a mixture of pictures and formatted text. Image files of various types are supported, including bitmaps, JPEGs, icons, and even animated GIFs. Add new page tabs and rename them whatever you wish to help get your life organized. In addition to the calendar on the top toolbar, you have a month-view calendar bar at the bottom of your diary.

This calendar bar not only allows you to view and select any day of the current month but also highlights which days of the month you have made entries in your diary. Features include the ability to create and open as many diaries as you wish; diary files that are fully encrypted and password-protected; the ability to search the entire diary for matching entries; the ability to insert clickable hotlinks, URLs, and links to other diary pages; and the ability to save diary pages to HTML to publish to Web. Version 3.41 include unspecified updates.
