If you only install one job app, make it LinkedIn. That’s not because it has everything you need, but because it’s where recruiters actually look. A solid profile can bring opportunities to you, which is a very different experience from applying to dozens of places all day.
LinkedIn is also one of the easiest ways to figure out what a role really wants. Job posts often include the hiring team, the recruiter, or people already doing the job. That makes it easier to tailor your application, and it can help you find a warm intro instead of being another random candidate.
To get the best value out of LinkedIn on your iPhone, set up job alerts for your target titles and locations, then tighten the filters until you’re not getting useless job opportunities. Also, don’t ignore the messaging side. A short, respectful message to a recruiter or hiring manager can create a more personal moment than your resume alone.
