The Android app joins Monster’s existing apps for the iPhone, iPad, and iPod touch.

The Monster Android app can be downloaded for free on the company’s website and in the Android Market. The app offers access to jobs, allows user to apply for positions and mange their accounts.

Monster has also introduced an extension for the Chrome browser. The beta release is available via Google’s Chrome Web Store. When a user is browsing using Chrome, the extension will automatically check for jobs posted on Monster based on the URL visited.

If jobs are found, a Monster sidebar appears and displays the number of jobs. Users may view the jobs without navigating away from the site, and then also click to apply on Monster. The sidebar can list up to 99 jobs that are posted within the last 7 days. Alternatively, users may also click on the small Monster icon in the URL bar to go directly to Monster’s job search results to view all jobs for the company.

“Influenced by recent trends in social and mobile, job seekers are changing the way they engage online. Monster is continuously evaluating these trends and adapting our products and services to serve job seekers and, by doing so, extending the reach to our employer customers,” said Vasu Nagalingam, Senior Product Director for consumer platforms at Monster Worldwide.
