Memoir is a simple note-taking program where you can write your own thoughts like in an actual diary or enter memos for work. The application brings you a user-friendly interface, allows you to export and print entries, and share your memos via email directly from its main window.
You can customize the appearance of your notes by selecting the preferred font style and size, importing pictures, and much more. After you write your memos, you can email, print or export them to your local directories.
I like that the program also features an option allowing for password protecting the stored notes. This way, you can prevent unauthorized users from accessing your private memos.
My only concern regarding this application is the fact that it doesn't allow you to export notes individually (it only exports the entire collection of memos or journal entries).
I'd say it's worth trying this program on your Mac as long as the disadvantage mentioned above doesn't mean much to you. The app comes with an affordable cost and offers you plenty of useful features.
