The tablet app is available for Android from today and on Apple’s mobile OS “very soon”. Microsoft didn’t get a mention. It includes a “lean back” version of Hangouts, larger images and sharper text.
Google also showcased the new Nexus 7 tablet and the next iteration of Android, Android 4.1 or Jelly Bean, to accompany today’s app release.
Overall, Google+ now has 250 million registered users (which includes those that have simply “upgraded” their Google account to include Google+), with 150 million or so of these classed as being active (signing-in) on a monthly basis. Around 75 million sign-in on a daily basis.
These statistics should be approached with caution though. Users that sign-in and are classed as active don’t necessarily have to interact directly on Google+. Instead a Google user that performs a Google Search or watches a video on YouTube can be classed as active on Google+ as all services are intrinsically linked.
Users have been found to spend on average 60 minutes per day on all Google products and 12 minutes per day on Google+. Compare this to an average time of 23 minutes spent per day on Facebook.com. More users interact on Google+ using mobile than desktop, hence today’s focus on mobile.
