Job application apps and other online tools have officially gone viral. Never before has it been easier to keep track of jobs and contacts on the go. A great example is the old standby, Monster.com, which now has apps for the iPhone, Droid, and iPad that allow you to keep your job search — including resume, cover letter, and listings — with you at all times. Because if you’re hunting for a job, the last thing you want to do is to be a day late — and possibly a job short — just because you missed a posting.
