Top 5 best DJ apps for iPhones and iPads1
When it comes to DJ or music-making apps, Apple's and iPhones and iPads have always been ahead of the pack thanks to a combination of two tightly connected factors: latency and developer support.
Historically, iOS devices have always offered minimal sound latency, which meant that iOS apps can seemingly instantaneously output audio when the system dictates it to. Modern iPhones and iPads usually have sound latencies measured somewhere between 7 and 10 milliseconds. Up until Android 6.0 Marshmallow, the sound latency of devices running Google's mobile OS was somewhere in the 100ms range.
Since iOS has historically allowed developers to create pro-audio apps, Android has yet to become the go-to platform for any quality-focused music-making mobile app, and this for reasons that only go on top of the usual ones such as performance inconsistency across devices and fragmentation.
Djay 2 / Djay Pro
If you're looking for the ultimate iOS DJ-ing experience, then Djay Pro is probably what you're looking for. The enhanced version of the app, which is only compatible with the Apple iPad Pro, is the only DJ app for iOS that can mix up to four songs and two 4K videos simultaneously, for the complete multimedia deejaying package. Unfortunately, the price of $19.99 is prohibitive for most users.
In the world of DJing apps, Traktor is one of the most popular solutions for Windows and Mac, and the company's iOS app, which works on both iPhones and iPads, expands the experience to Apple's mobile devices. If you've ever used Traktor on a computer, then you're already familiarized with the workflow, although there are some differences that you should take note of.
Traktor for iOS comes with all of the sound effects available on the desktop version, but the number of decks is limited to two, not four like on the desktop version. Unfortunately, the app can only load songs from iTunes library, meaning that you should be looking elsewhere for integration with Spotify or Soundcloud.
Cross is a very straightforward deejaying app for iOS that's built around the basic setup of two decks on the side and a mixer with EQ in the middle. Cross DJ comes with a looping function that's easy to use but very effective, and many users appreciate the accuracy of the cue points.
The free version of Cross DJ only comes with a couple of effects (flanger and echo), but you can get additional sound-shaping functions through in-app purchases.
Serato, which is another popular software used by professional DJs, also comes in a mobile flavor for Apple's iPhones and iPads. Unlike Traktor, however, which offers a nearly equivalent mobile app, Serato's iOS app adopts a different approach.
Aside from the ability to reorder the songs in a playlist, Serato Pyro doesn't really offer too many options. As such, the app isn't one we can recommend to would-be DJs. On the other hand, if you just want to be in control of the playlist while making sure that song transitions don't kill the vibe, then Serato Pyro is just what the doctor order.
Like Serato Pyro, Pacemaker can automatically mix songs selected from either iTunes or Spotify. However, Peacemaker also offers a three-band equalizer (which can prove to be indispensable on certain sound systems and in certain environments). Furthermore, the paid version also allows you to apply sound effects to the songs, such as Hi-Lo, Reverb, ChopChop, 8-bit, Roll, Echo, Loop, and Beatskip.
