Google's Android Market platform has achieved the 400,000 active apps milestone.
According to app metrics service provider Distimo, around 100,000 developers are now offering 400,000 active applications on the Android app store, Slashgear reports.
Distimo said in a blog post that almost two thirds of the active applications on the Android Market are free.
The company also said the percentage of free applications on the Android Market had increased by 60 percent in April 2011 to 68 percent at the end of the year.
"Interesting to see is that Android Market has taken 31 months to reach the 200,000 milestone, while Apple only needed 22 months to do this for iPhone apps," the company observed.
"However, Android Market needed only four more months to pass the 300.000 milestone, while the App Store for iPhone needed eight more months after Apple hits the 200,000 milestone," it added.
The company also points out that Android Market reached 400,000 apps only 4 months after it had achieved the 300,000 milestone while the Apple App Store took 7 months for the same. This milestone would be a huge one for any company.
