If you ever find yourself in a situation where you have to write down a list of things to do, you should definitely consider using a notebook - better yet, a notebook that's found within the convenience of your mobile device. Not only can you use your notebook to make lists, but you can also use it to organize your thoughts and make sure you don't forget anything. Notepads are useful for a lot of things, but the main thing is that they help you to keep your thoughts and ideas organized.

This app, called "دفترچه یادداشت فارسی رمز دار" - or "Encrypted Persian Notebook"  is an encrypted notebook in Farsi that is useful for making lists and keeping track of your daily activities and weekly plans. It also includes the option to compose a video note, in case you do not want to scribble your thoughts using words.
