Nearly half of all Instagram users are now using the Android version of the photo editing and sharing app, just one year after it was launched for the Google platform.

More than one million people downloaded the Android version of Instagram during its first day of availability, with the app previously only having been available on Apple’s iOS platform.

Philip McAllister of the Instagram Android Team said on the company’s blog that the introduction of the app to Android had helped make the Instagram community “more global than ever”.

Facebook acquired Instagram for $1 billion in April 2012 with subsequent changes in the app’s privacy policy causing concern for some users. However, Instagram co-founder Kevin Systrom said the photo sharing app would not claim ownership of users’ photos.

Facebook founder and CEO Mark Zuckerberg said in September 2012 that Instagram had secured more than 100 million users across iOS and Android.
