Instagram, the hugely popular iPhone photography app that evokes 1970s style, has announced it's finally developing an Android app.

The company believes its membership base of 15 million could double with its Android launch, CNET reports.

"We have two people working on Android now," Kevin Systrom, CEO of Instagram said at LeWeb in Paris. "I'm excited to be able to see our numbers today nearly double."

Though no additional details or timeline on the Android app's arrival were revealed, Systrom says the company is still focusing primarily on increasing its membership.

The app's biggest change to date was the September rollout of Instagram 2.0, which brought live filters, instant tilt-shift, high-resolution photos and a speedier experience.The company also announced at Le Wed that is has plans to introduce ads to the free app.

"Obviously, we didn't start a business to not make money," Systrom says. "Our focus now is on growing the network. You really need to build up the network, or no advertisers care."

Do you think the Android platform will be a game changer for Instagram? Will the app continue to gain popularity?
