TechBits: Google revamps Gmail app for Apple devices Google took a second swing at its Gmail application for Apple devices with a mandate to make the app simple and easy. In many ways, it succeeded. The revamped app allows users to sign into up to five accounts at a time and is much easier to use. Messages now automatically resize to fit your screen, and the app will sync with Google Calendar and the Google+ social network. Getting to labels, using the archive and marking messages as read and other controls are intuitive as well. Despite multiple improvements, however, this app still has drawbacks. For example, users can't choose to see e-mails from all of their accounts at once - they have to switch identities first. While that's good for keeping your accounts straight, it's not that helpful when you're trying to catch up on all aspects of your life at a glance.
