A free app for Android, by LinkedIn.

With the LinkedIn Recruiter app, you can easily search for candidates and send them messages from anywhere. You can also collaborate with your team by sharing profiles with them and adding tags to them. The app keeps all of your data in sync across multiple devices, so you don’t lose any of your information. If you’re looking for a new position, you can search the entire LinkedIn network for people who are in the field you’re looking to recruit. You can also search by city, state, country, and more. The app will then display the most relevant profiles and candidates to you.
