A free program for iPhone, by Pioneer DJ Corporation.
WeDJ is the world’s best mobile DJ app, and now it’s for iPhone!
What you can do:
You can mix songs from two different sources at the same time (e.g. you can mix music from your iPhone with music from a streaming service such as Beatport LINK or SoundCloud Go+). You can loop parts of a song, and you can change the tempo of a song by using the tempo slider. You can use the EQ to change the sound of the music, and you can add effects such as Reverb and Echo. You can use the sampler to get a better idea of the sound of the song.
