Overall, GKeep is a great note-taking app for iOS users. It is simple to use, versatile, and feature-rich. If you are looking for a way to keep track of your thoughts and ideas, GKeep is an ace option.
For me its all about speed and ease of use. I'm not someone who has structured notes, so all those extra features only slow me down. Keep is as simple as it gets, and I know it'll be there no matter what device I use. Highly recommend you give it a try if you haven't already
