Apple's Notes application is a very useful and organizational tool for creating detailed notes that can be accessed anywhere through Apple devices connected through iCloud.
Once the application is opened, click on the image on the bottom right corner to create a new Note document. When clicked, the application will create a new Note document where a variety of features can be accessed at ease at the top bar above the keyboard.
To access the text formatting and font feature, press on the 'Aa' image near the top left of the keyboard.
To check off an item from the checklist, simply tap on the white circle to make it change colour and have a small checkmark to indicate the item being crossed off the list.
