Deep Notes is a simple application that allows you to create to-do lists in a hierarchical order. For every item you create, you can assign a specific color and create subcategories. There are various colors to choose from for your tasks, but you can also select your favorite ones from a huge palette. The toolbar of the program is also completely customizable, so you can select exactly the options you want to see. Moreover, you will also be able to select its display, printing font size and type.
Unfortunately, you won't be able to create reminders or alarms for the notes you add. For this reason, you should check the program daily, so you don't forget to carry out pending tasks. The program is also helpful to write ideas that come to your mind at a specific moment. The notes you create can be easily erased once you complete the task or don't need them anymore, and they can also be printed.
To sum up, if you are looking for a really simple to-do list creator for your Mac, Deep Notes may work for you, but don't expect too much from it.
