Deck - Audio player for DJs

Deck is a fully featured audio player built for DJs that turns your iPhone into a standalone DJ deck.

Use Deck to:

• Add an extra digital channel to your existing turntables
• Create an ultra-portable DJ setup
• Keep an emergency backup deck in your pocket
• Connect your iPhone to one of your mixer's line inputs with a USB-C or Lightning to RCA cable. Now you can play, cue, loop and beat-match digital tracks alongside your other turntables — using just your phone.

Deck includes many professional DJ and mixing features:

• Track nudge and tempo adjust using the beat-match pad
• Frequency-colored waveforms — bass, mids and highs as layered color — with a choice of color themes
• Detailed and full-track summary waveform views with multiple zoom levels
• Automatic BPM detection and beat grid, with manual override and tap tempo
• CDJ-style cue point controls and hot cues with ultra-low-latency playback
• Musical key display
• Quantization for cue points and looping
• Beat-synced auto looping
• Effects: high/low pass filters, echo, flange, reverb and more
• Media library with playlists
• Reverse play and motor kill
• Background playback

Example setups:

• Add a digital source to your vinyl setup without dedicated hardware decks
• Two iPhones and a compact mixer make a complete, professional DJ rig that fits in a small bag
• Deck contains no ads or in-app purchases and collects no data.
