The Shepper app allows you to both see jobs based on custom Areas you choose or jobs that are near to you.

To change how far away jobs are shown based on your current location you can make some adjustments by going to your Account and tapping on the cog shaped settings icon. From here you can use the slider to change the range from 0.5 km all the way to 50 km.

If you don't want to receive updates for nearby jobs you can also turn off notifications.
