Evernote Don't just organize your money, organize your life! Evernote is great for that. Evernote is more than just a traditional to-do list. Sometimes, it's less efficient to jot things down. Use the camera to take picture notes. Use the microphone to record audio notes. Even scan PDFs. Tag everything to stay organized. Use labels or even geotag things by location. Although the basic features on the app are free, premium subscribers can access notes offline and share notebooks with friends. The free app is compatible with iPhone, iPod touch, and iPad, but requires iOS 5.0 or later. It is also available for Android.
