Google's Gmail for Android has become the first app for the operating system to get one billion installs.
Google vice president Sundar Pichai confirmed the milestone on his Google+ page. The relevant page on the Android Play Store shows the same numbers. "Great to see the Gmail app on Android just crossed one billion installs!!" wrote Pichai.
The number may be slightly skewered as users could have downloaded the app several times as they move between devices, and many devices have it pre-installed, but nonetheless it is still an strong indication of Gmail's popularity.
It is the second one-billion milestone announcement from the firm this week as founder Larry Page said there are one billion Android devices in use and many millions of searches.
"The activity on Google Search is astounding. There are over 100 billion searches a month (a whopping 15 per cent of which we've never seen before)," he said.
"In less than six years, over one billion Android devices have been activated (and growing fast) – creating an amazing platform for the increasing number of app developers globally."
Page said Google is still growing and learning, and added that the firm is still far away from his search vision.
"Sixteen years after we started Google, we're just scratching the surface of what's possible. Sergey and I come to work each day excited about what lies ahead and the extraordinary people we work with," he added.
"Googlers make everything possible, and they are our future. And, while the world may have changed over the years, we're as motivated by the potential to make a difference in people's lives today as when we first started."
Google is tipped to relaunch Gmail with a more Google+ look and feel in the coming months.
