About DuoCal
DuoCal ~Compare Calendars Side by Side~ DuoCal allows you to line up calendars of the same month of different years or any other months you like top-and-bottom and compare them. ●DuoCal Features ・Allows you to create calendars for different purposes and easily switch between them. ・Allows you to display 2 calendars top-and-bottom, making it easy to compare monthly calendars for different months and years or various monthly calendars in different years, for example. ・Allows you to easily share your calendars with multiple people. (Sharing calendars require both the inviter and invitee to have Dropbox accounts. DuoCal account registration is not required.) ・Allows you to sync iOS calendars. You can also sync your Google calendar by syncing your Google Calendar with your iOS calendar. ・You may attach as many labels to your calendar as you want for different purposes. You can choose between 34 colors and 4 sizes as well as 2 types, text only or image+text. ・You can also create label templates. By creating label templates you frequently use, you can customize your calendar to make it easier for you to use. ・You may also attach labels to parts other than the dates on your calendar or create short memos separate from the dates. ●Usage example ・You can use it like a 5 year calendar or 10 year calendar. By using the labels as diaries with photos, you can easily relive your memories in the current month 1 year or 5 years ago. ・As you can create multiple calendars separated by various purposes such as private, work, family, and more, you can make a calendar that is easy to view. Additionally, by lining them up top-and-bottom, you can plan your work schedule while comparing it with your private schedule. ・Use the share function to easily share the information with your family or acquaintances. You can use it like a portable fridge calendar. ・By recording reservations or revenue on labels, you can compare reservation status for the same month between different years and between different months. ・You can also record events with clients in the previous year on your calendar and display this year’s calendar on top and last year's calendar at the bottom to establish the year’s plan to fit your client’s needs while checking last year’s circumstances. ・You can use the share function to easily sync the information between multiple devices. For example, you can use your tablet at home and your smartphone when outside to manage your schedule. ●DuoCal Convenient Features (Calendar Management) ・Allows you to combine calendars. You can easily combine calendars that you created separately into a single calendar. (Calendar View) ・You can use pinch-to-zoom to enlarge the calendar. If your phone screen is small, making it difficult to view the labels, you can intuitively enlarge it. ・Tap the View Mode button to switch to View Mode. In View Mode, you can zoom in on the data by tapping and holding on specific dates. This feature is useful for quickly checking all the details. (Calendar Sharing) ・You can share your calendar with multiple people by using Dropbox. All you need to do is send an Invite email to the person you want to share it with. No DuoCal account registration is required. ・Send an email to yourself to sync your calendar on multiple devices such as your smartphone and tablet. (Other Features) ・You can also backup your calendar to iCloud Drive. ●Use add-ons to add functionality ・Purchase add-ons to remove ads and increase the display area. This will make it easier to view the calendars when you line them up top-and-bottom. ・You can import Palu Calendar backup files. You can import calendars that you have created on Palu to DuoCal. (Calendars imported from Palu cannot be edited.) *”Dropbox” is a trademark or registered trademark of Dropbox, Inc. *”Palu” is a product of MetaMoJi Corporation. *The screenshot shown here is the app with add-ons that remove ads.
