What I would do without Evernote! Such a great tool for capturing all your great ideas, web pages, articles, audio files, etc. The free version will be plenty for most users. It works on Mac, PC, mobile devices, and more.
Store and share your files across multiple machines and platforms. Access your files wherever you are. Share with your friends. Collaborate with others. Use the cloud to backup your files. Free and paid versions, but the free version will be sufficient for most people.
I get my very best ideas in the shower, and for too long I had no way to capture them. By the time I found a pencil, these great ideas were gone. Then I found Aqua Notes. They are fabulous little notepads and pencils that attach via suction cups to your shower wall. Now when inspiration strikes, I can write it down!
Great tool for list making. Very simple to use but very powerful. Works on desktop and mobile devices. Free for up to 500 items per month and a paid option offers more features. Good for your to do lists but so much more. Wonderful way to capture ideas for stories, and ways to use stories before the ideas get away!
