You can add lists and items. You can check the number of items in each list on the top screen (*The first screen shot is an example of the top screen).

By adding check marks to items that you have finished, you can easily distinguish them from items that you have not finished yet. The number of items with a check mark in each list is excluded from the number displayed on the top screen. (You can add a check mark by touching the circle on the left side of the item.)

It is useful to add exclamation marks to important items. The number of items with an exclamation mark in each list is displayed in a red circle on the top screen. Moreover, they are displayed on the app icon. So, you can easily notice them. (You can add an exclamation mark by long tapping the circle on the left side of the item.)

You can share data for lists and items by email and AirDrop. By sending data to yourself by email or saving data to files, you can use them as backup.

You can copy, cut, and paste a list and item. By using this functionality, you can easily duplicate a list and item, move an item from a list to another one, and so on. You can also merge two lists by cutting a list and paste it in another list.
