Gmail for Android now boasts a respectable figure of more than one billion downloads of Google Play Store. This is the first application that has crossed this figure, after Google Play Services, which comes pre-installed with every Certified Android device. This figure reflects only a single download, not the total number of downloads, including repeated Downloads. This does not mean that there are one billion active Android Gmail users, because there certainly involves a number of abandoned or duplicate orders. When it comes to Android, the service in April 2013 had 1.5 million daily activation. We can probably expect this number to be increased during the Google I/O 2014 conference.
