The great thing about offering a hugely-popular development environment for a successful mobile device is just how quickly 1000,000 apps can reach your App Store, but Apple’s developers complain app discovery is flawed, leaving many earning less for their work than they think they should. However, the other great thing about a popular developer environment is that problems are solutions waiting to happen, and socially-connected app discovery is the iPhone developer response.

One of the first of what we predict will be a wave of these solutions is Chorus for the iPhone and iPod touch. Developed by envIO, the app helps us find whuch applications our friends are using.

You can connect with your friends to see the apps they're using, which apps they rate highly, and to stay up-to-date on new apps as they come through.

Chorus features real-time feeds from your designated friends, displaying the apps they are downloading, and what they are saying about them.

"Chorus makes the whole process of app discovery much more fun and engaging. Chorus helps users connect with trusted friends from social networks like Facebook and Twitter," said Manish Jha, President and CEO of envIO networks, the company behind Chorus.

"iPhone users already ask friends and colleagues about cool, new apps. Chorus makes it simple," said Linda Barrabee, advisor to envIO networks.

Chorus uses envIO's proprietary Social Genome technology to match favorite apps against those your friends use, building a personalized and relevant list of recommended apps.

Here’s some of its features:

Check out what your friends are downloading, find out what they think before you buy or download.
Share opinions with your friends, rate apps and post your own reviews.
Get customized recommendations based on what your friends are doing.
Learn about the hottest new apps.

It’s a free App and you can go grab it right here.

NB: We've written to the developers requesting info on the international launch of this App, no response received as yet.
