Double Twist , the app with more than a catchy name, because it enables people to sync their iTunes music library with their Android phones.

The app is limited when it comes to transferring photos, but it's a great alternative for those who do not want to carry an iPod just for music, said The New York Times.

The Double Twist Steps

Using the Double Twist involves two steps. First, the user has to download both the Double Twist desktop application (through doubletwist.com) and the Android app. Second, the user synchronizes the media on the phone and computer.

Bob Tedeschi of the New York Times shares his experience with the Double Twist:

"Unfortunately, the initial syncing process isn't quite as seamless as it could be. When you start the desktop application, it greets you not with a guide to getting started, but with a pitch urging you to buy the doubleTwist AirSync app. As an alternative, the desktop application says, you can "sync via USB for free."

So I grabbed a cable with a micro-USB plug on one end (for connecting to the phone's power source) and a conventional USB plug on the other. With the doubleTwist app open on the phone, I connected the Droid2 to my Mac."

Success. The connection set off the opening of a new window on my desktop screen, prompting me to import music, videos and photos from my phone to the computer, or sync my iTunes music or videos to the phone."

Instead of trying to export my entire music library to the Droid2 or selected playlists among the many I have, though, doubleTwist asked if I wanted to choose among three playlists: "Most Played," "Recently Added" and "Top Rated."

After some unsuccessful troubleshooting, I chose to download all three playlist options, and five minutes later, I had 75 songs on my phone that weren't there before."

I also received an error message stating that 47 of the songs I'd been downloading to the phone were not available for transfer because the songs had not been upgraded to iTunes Plus."

For the uninitiated, iTunes Plus is an audio standard introduced on iTunes in 2007. Tracks are of higher quality and free from copy protections. As a result, you can burn music to a CD as often as you like, or play songs on multiple devices without restriction."

But if you bought songs on iTunes before 2007, as I did, you'll need to upgrade them if you want to transfer them to an Android. (To upgrade, look for the iTunes Plus link on the right side of the iTunes homepage. The cost is 30 cents a song or $3 an album."

Double Twist's AirSync: Wireless Syncing

Priced at $5 on Android, the app is a fast alternative to transferring iTunes music from desktop computer to phone. All one needs is a Wi-Fi connection, instead of connecting phone and computer with a micro-USB.

"Once Android users set up their iTunes on the phone, they will enjoy some other features that make it a more versatile music player than an iPhone. As the song plays, for instance, you can tap on the musician's name and a box appears, offering options for buying more of the artist's songs or watching related YouTube videos, for instance," added the Times.
