ColorNote is a very simple and practical application that can help you with your studies or whatever you need. I use it on my smartphone and find it great to use.
It is a simple memo pad (and agenda) in which you can make any type of annotation whenever you need it, and it even has the possibility of making notes in text or in a checklist. I find the checklists extremely practical because you can write down whatever you want and check off as you do it, so that you don't forget anything, and you can also make checklists for tasks that you have to do all the said and cross off ( and removing the strikethrough) each day as they are made.
All the notes You can archive, delete, review items, lock or create a reminder. And if there is something good about the application, it is that you can include dates to remember tasks to be done (every day or on a specific day), making it almost impossible to forget anything.
On the other hand, the notes can be differentiated in colors. This can be useful for distinguishing between class notes, other assignments, personal notes, and even your shopping list. And of course they can also be password protected.
These are just some of the advantages and functions of the application, although it is best if you download and explore it yourself to find out what such a simple Android application can do for you.
