Native email on the iPhone and iPad has always left a lot to be desired, particularly if you are a Gmail user. Same has historically been true for Gmail users on iOS. However, with a major refresh of the universal iOS app yesterday, Gmail has really come into its own on the Apple mobile front. I’m not sure whether buying uber-popular email app Sparrow had anything to do with it or not – I’m just happy with the results.

Obvious changes include improvement in the physical UI, which is simpler and easier to view, and responds beautifully on my iPhone 5. Other improvements clearly had me in mind as well – I am thrilled that the newest version not only has multiple sign in, but allows really simple switching between accounts with icon-based buttons. You can add up to five Gmail accounts within the app – I’ve filled up four slots already.

Another new benefit is better integration with other Google products – clearly the direction Google has been heading in with all its products. You can now add calendar invites and events from within Gmail without having to switch to another app. And you can post to Google+ from within your Gmail, such as +-ing a post.

There are notifications, now, if you prefer to have your incoming email accompanied by a charming tone and a lock screen note. Really. Some people like that.

Easily add photos or scribbles to your emails. Yes, scribbles. You can draw something and attach it.

Search in the iOS app is now predictive – Google will offer up options as you type your query. Certainly speeds things up a bit. And, with infinite scrolling you can slam through 150 emails with a few swipes, without having to reload after 50 items.

All of the new features have usability in mind. I like the new app so much, I am thinking of moving it to the tray. A lot of these features have already been available in the Android version, which really is no surprise at all. And Google also updated the Android version yesterday as well, keeping it well ahead of the iOS version with pinch-to-zoom on individual messages and swipe (left or right) to delete or archive. There is also an ability to “auto-fit” a message to your phone’s screen, a thumbnail view of attached images that can be tapped to open a swipeable gallery, and the ability to attach phone-captured videos to an email. For phones with Android 4.0 or higher, unfortunately, but still pretty cool.

Both apps are free. What are you waiting for?
