There have been jobs apps available since the existence of the app store, so they're nothing new. However if you're in the tech field and looking for a job you may be interested in this jobs apps particularly.
This app is a focused jobs app which mainly concentrates on tech jobs such as app developers, web designers, graphic designers...etc.
When looking for a job you can choose from full-time, freelance, contract, internship or telecommute jobs. So they have most work types covered. You can then choose a category too depending on which field you are in, whether it be UI design or information architecture. It's a good way to narrow down the list so you're applying to jobs you have experience or education in.
Once you've filtered out the jobs you're looking for you get a list of the jobs available. It'll display what the job title is, the logo of the company hiring, location and when it was posted. When I looked there were some big names on there including Rdio, Ministry of Sound and many others.
When you tap on a job you like you can read the full description and you get the name of the company. They add nice header images which move which makes a very nice touch. There are then a number of options available. You can find the exact location of the job and it'll show it to you on a map. You can apply for the job right from your phone, mark it as a favourite, send it via mail or tweet it.
The overall design of the app is brilliant and makes finding jobs a breeze, unlike many other jobs apps I've come across. The app is only £0.69, a small price to pay if you're looking for a job.
