Google Keep is a free note taking app that’s made to capture notes, lists, photos, and audio. It is available on both Android and iOS.
Google Keep IS NOT as powerful as OneNote - rather it is a simple note-taking tool.
Are you a non-techy person looking for the simpliest way possible to keep personal notes? Simplenote might be the best choice for you.
Available for Window, Mac, iOS, and Android, Simplenote is a plain text app that will let you organize your notes with tags. However, you CANNOT add web clippings, images, audio, or integrate it with email.
