Gmail app hits 10 billion installs on Android, only slightly higher than your unread emails - Android Police
As we look forward to seeing how it will continue to evolve over the next 20 years, we're witnessing the Gmail Android app pass a significant milestone, as the Play Store tallies up 10 billion installs.
Granted, Gmail comes preinstalled on a lot of Android devices, but we're not about to let a little thing like that take away from this accomplishment.Gmail is just the latest in a string of core Google apps that have already crossed the 10B threshold, starting with Play services and followed by YouTube and later Maps.
