Google Keep is a note-taking app similar to Evernote, which I have used for several years. You have to buy one of the pay versions of Evernote if you need more features than the very limited free version, but Google Keep is free. Keep works seamlessly with all the Google apps, such as Chrome, Drive, Docs, Gmail, and Calendar. You can capture notes, audio, and photos with the press of a button. You should know that all your captures are stored on Google Drive and count against your storage limit. I downloaded on my Samsung phone and my iPad and am looking forward to using it.
