Google Keep
Jot down notes and search all in one place

Google has added a new Web and Android app to its lineup, moving into the growing field of note-taking apps. Google Keep, as the service is called, lets you jot down quick notes, include photos and record voice messages. While it doesn’t have the same organization options as other full-fledged note services, it does have a full search function, because it’s Google. Free, on the Web and on Android devices running Android 4.0 and up.
