Basically it's an app which updates daily, telling you about other apps which originally came at a price, but has recently become free! Some of these apps may be only free for a limited time, as the producers want to bump up the publicity and ratings for their app.
It comes with a short description about why they chose it as well as highlights if it's iPhone or iPad compatible. So it saves me time from trawling the internet, and I have found many useful bit and pieces that have made my life easier in the classroom. For example, Phoster which now costs $1.99, but was free for a limited amount of time. I could make really fancy posters to stick around my classroom. I've only had time to make one with a Nelson Mandela quote on it, but feel free to use it if you like.
