How to find an internship?


I’ve just read a blog ‘Working Towards a Future’ which conflicts with the information which was given to me by one of the Careers Consultants at my University.
Right now, I’m faced with the task of finding an internship.
My internship report will be part of my assessment, so should I continue sending speculative applications to companies or should I go down the mobile app route?
Has anyone had any one found a job/internship with a mobile recruitment app?
