Apparently, people likes the Gmail for iOS UI revamp os much that Google wanted to expand the new look to its mobile web app.
"Since launching the rebooted Gmail app for iPhone and iPad in December, we’ve heard from many of you that you like the redesigned UI, along with new features such as improved search and integration with Google Calendar. Today we’re rolling out a similar refreshed look to the Gmail mobile web app as well as Gmail Offline that includes many of these same changes," says Google's Gmail team in a Google+ post.
Basically, your mobile web experience inside Gmail is going to look and feel a lot like the new iOS app. And that UI change affects quite a few Gmail users (as plenty of device rely on the mobile web experience).
Google launched v.2.0 of its Gmail iOS app back in December. It features an entirely updated look, plus improvements like Gmail profile pics in messages, new animations, and infinite scrolling.
It also added some new features to search within the client, like better automcplete and Google+ commenting.
Google added Google Calendar data to Gmail search results late last month inside the Gmail Search Field Trial.
