"Hook is exactly what the doctor ordered. Many apps came close but you nailed it." —DJ puzzle

"Hook is definitely the most fun I've had making music on iOS.  The sampling options are vast and the editing is intuitive.  It's connectivity and versatility makes it a powerful performance tool and production sketchbook." — Starkey

5 STARS "Most impressive DJ mashup & sampler / editor I've seen on iOS so far! It's like the best of all other apps combined in one and all of the latest developments integrated like recording or importing ur own music and inter-app audio." — App Store Review

This is the free iPhone version of Hook. There's also an iPad version for 13 bucks. The feature sets are identical, but the iPad version is optimized for the larger screen, including iPad Pro. The iPad version also comes with 4 additional sound packs with over 500 samples.

Hook is a new music performance, mashup, and DJ app for iPhone and iPad. Arrange and trigger loops on a grid and create dynamic, expressive transitions with the Flux Fader — a multitouch "smart crossfader" that allows you to expressively make transitions between any combination of tracks/cells on the fly. The Flux Fader includes a two-axis control with 9 riser synths, glitch and gate effects, tempo-synced filter sweeps, an EQ, beat drop, tape stop, and filter drop. Combining all these to make transitions is the heart of playing live with Hook. Hook includes a full editor complete with auto transient slicing and waveform editing. Tight integration with AudioCopy makes it easy to drop in your own loops and sounds from other apps.

Real creative power can be found in the integrated sampler — record from mic/line, other apps via inter-app audio, and grab hooks from iTunes and Spotify. Change tempo in real time, and keep all your hooks in sync. Hook is a killer mashup tool with a full mixer, tons of tracks, integrated FX bus, per-cell fx, transpose, time stretching, tuning, timing and trigger settings, and more. Imagine the clip launching capabilities of Ableton Live in a futuristic multitouch environment.

Editors’ Notes

Just try to stop yourself from nodding along as you make beats. Hook packs enough features to please even pros with its advanced interface, while live DJing gets a special boost from its Flux Fader. Its smooth transitions ensure that the beat drops exactly when we want it to.

What I have been waiting for!

This is exactly what I have been waiting for. I have played around with all kinds Dj Apps, and this is by far the best when it comes to customizing your music. Arranging, and making music just the way you want. It has it all. Just give it a try.

Kills battery while dormant

This app has amazing features. It gives you a ton of versatility and the best part is it's free. You do have to use your own sounds or buy sound packs though, which is a given. However, I noticed that this app will consistently use 50% or more of my battery, even without being opened in the entire day, and having background app refresh disabled. It is a deal breaker being that bad. It completely rips through my battery even when I don't use the app, at all. 5 stars if that issue didn't exist because that's insane.
