Magic Piano, Smule’s most downloaded app, is coming to Android.  Smule made the announcement Tuesday, making it the second Smule app to cross over to Android.

Smule’s Songify app, which uses artificial intelligence to turn spoken words into a song, was launched on Android for Google Play last month and has already reached two million installs. 

Magic Piano is Smule’s most successful app, with over one million songs played every day.  Over 500 million songs have been played across Smule's apps since the company launched in 2008, and its apps have seen a combined 48 million downloads.

The new crossover to Android brings with it some cool new Android-only features, including the ability to share your music with others through SMS, Google+, and so on.

If you’ve never played with the Magic Piano app, it’s pretty addictive.  You simply tap the little orbs of light that show up on the screen to play the right notes.  The app lets you control the tempo and rhythm to put your own little creative spin on things.  The app comes with more than 200 songs from which to choose.

CEO Jeff Smith told me last month that the company’s decision to hold off on Android until now was a strategic move.

"In general, we were concerned that adopting a second platform too early would throttle our ability to innovate,” he said.  “We build extremely immersive experiences which fully exploit what the hardware has to offer.  It's hard to do so when you are aiming for the lowest common denominator across multiple platforms.  Therefore, we waited until we had more scale and for the platform to mature."

The company told me in March that most of the app usage happens on the weekends, with many users reporting that they play Magic Piano before going to bed.

Smule was founded in 2008 and has 45 million users across all of its apps.  Smule has raised $25.5 million to date from Bessemer Venture Partners, Granite Ventures, Shasta Ventures, and Floodgate. The company became profitable in 2010.
