mizutama Calendar is a vertical calendar application for iPhone that features illustrations by the renowned illustrator mizutama. It not only serves as a calendar but also functions as a schedule book, allowing users to easily keep track of their meeting schedules and appointments.

One of the main functions of mizutama Calendar is the memo feature, which allows users to write down notes for each day. The memo can be displayed in two formats - a simple display with only headings or a full text display. This flexibility makes it easy for users to switch between different viewing options based on their preferences.

In addition, the application allows users to attach up to 5 sticky notes as marks for each date. This feature is particularly useful for shift management or organizing tasks. Furthermore, mizutama Calendar offers the option to switch between three different calendars for various purposes, such as work or personal use.

One standout feature of mizutama Calendar is its full screen mode, which displays the entire schedule without the need for scrolling. This mode is especially convenient for users who prefer to view their schedule at a glance. Users can also take screenshots of the full screen mode and easily share their schedule with family and friends.

To ensure privacy, mizutama Calendar provides the ability to hide memos when sharing the calendar with others. By tapping the icon in the upper right corner of the screen, users can choose to display only the sticky notes, making it ideal for those who want to share their schedule without revealing personal details.

Please note that mizutama Calendar displays advertisements while in use. However, these ads do not detract from the overall functionality and usefulness of the application.

Overall, mizutama Calendar is a visually appealing and practical calendar application that offers a range of features to help users stay organized and manage their schedules effectively.
