It took Google 20 months to reach the 1 billion apps installed on Android, five months later they had reached the 2 billion mark and now it's sitting at a very impressive 3 billion apps installed. If Google continue going at this speed we should see 4 or 5 billion apps installed by next month!

During Google's first-quarter earnings call today, senior vice president for commerce had said that the platform has grown from 2 billion apps installed to 3 billions apps installed in just two months. Huber also mentioned that app installs are up by 50-percent quarter-over-quarter (from Q4 2010 to Q1 2011) and that Android-powered devices are seeing 350, 000 activations per day.
