You can use Google Keep to create, share, and collaborate notes quickly and easily. Since Google Keep syncs to Google, notes are accessible to you and anyone you share them with virtually anywhere:
Create: Take notes using text, photos, or your voice, and add multi-purpose checklists.
Organize: Drag & drop your notes and lists to rearrange them, and archive them when you no longer need them.
Share: Send notes to your contacts and collaborate in real time.
Access: Browse and search notes easily – you can use widgets on your Android device or even sync Google Keep with your Android wearable for quick note-taking and viewing.
