MeeDJ is a music-mixing console that affords you the ability to create music mixes and playlists from your music library. Available from both the Windows Phone and Windows 10 Stores, MeeDJ is a freemium title. That is the core app is free but there are plenty of add-ons you can pick up through in-app purchase.
While the myAppFree Deal cannot discount the MeeDJ app itself, what it has done is offer one premium feature free and discounted the other features. Through the myAppFree Deal, you get the "Additional Audio Formats" add-on free and the remaining in-app purchases are discounted 50%.
The deal won't last long, so if you've been itching to spin some tunes now is the time to save a little with MeeDJ.
