One of the most popular photography applications for the iPhone has quickly become one of the most popular Android apps. Instagram for Android surpassed 1 million downloads less than 24 hours after its release on the Google Play marketplace on Tuesday. The Android application opened its pre-registration last week, attracting more than 430,000 users. When the service launched it reportedly saw 2,000 sign-ups per minute, nearly crashing the company’s servers. The popular app allows users to capture photos and edit them using a number of filters that give images a unique retro look. Pictures can then be shared through Instagram, Twitter, Facebook and email. The company previously announced that it had more than 30 million users on iOS alone.
