Instagram claims that more than 30 million people are using its iOS app, which launched in 2010. 430,000 people have signed up to a waiting list for an Android version of the app.
"[W]e're thrilled to offer a way for Android users to join their iOS friends on Instagram to share their photos with the world," the company said in a blog post.
"We've been working tirelessly to make this new Android app a first-class mobile photo-sharing experience. We've been meticulous about translating the Instagram experience to the Android platform.
"The Android app offers an extremely familiar Instagram experience when compared to the iOS app. You'll find all the same exact filters and community as our iOS version."
Phones running Android 2.2 and above with support for OpenGL ES 2 are compatible with the new app.
