It's okay but will it stick around?
If it were just one app, and if it just came from a new developer, then you'd describe Google Keep 1.04 for iOS as lightweight note-taking software that's fine, but nothing special. It doesn't have a lot of functionality, it isn't for people who make a lot of notes, but it's quick -- and apart from some garish options, it also looks good. However, this isn't one app, it's part of a service, and it isn't from a new developer, it's from Google -- and that is a problem.
Google Keep ships on iOS over two years after Android release
Google Keep, the search engine's note-taking app, has finally arrived in the App Store, two and a half years after it launched on Android and in the browser. Available for the iPhone, iPad, and iPod touch running iOS 8.0 or later, the free app allows users to save notes and lists on cards, with individual notes able to be searched, assigned colors, and have time or location-based reminders assigned to them. Notes synchronize with Google's servers, so they can be accessed from multiple devices, and can even be shared with other users for collaborative purposes.
Full app for Android available, full integration with drive soon
As expected, Google has taken its note-taking service Google Keep live. The new app and service allow users to make color-coded notes, create checklists, and also add pictures to existing notes as part of its Google Drive-based suite of apps.
