Guanche’s DJ Booth

DAMM Systems designs focused, single-purpose apps — built by hand, run entirely on your device.

Our first release is Guanche’s DJ Booth, a two-deck DJ mixer for iPad and iPhone — built for DJs with an actual music collection, not a streaming subscription. Load tracks straight from your files, an external drive, or cloud storage through the Files app. No accounts, no ads, no internet connection required once your music is loaded.

Features

Two independent decks with jog wheels, pitch control, and Sync
Full mixer channel strip: trim, 3-band EQ, and channel fader per deck
Shared FX: master level, filter, and a beat-synced delay
Equal-power crossfader with a classic analog VU meter
Master Tempo lock for pitch-independent tempo changes
Play history, so you always know what you’ve already dropped
Designed for iPad and iPhone, in landscape, with a real mixer’s layout

Works with any MIDI controller

Plug in any DJ controller over USB — cheap or professional — and the app recognises it automatically. Teach it what each button, fader and knob does with MIDI Learn. It’s completely optional: the app works just as well with no controller connected.

Quick start

Open Settings and turn on MIDI Controller.
Open Configure mapping and tap Learn next to a control.
Press the button or move the knob on your controller. It’s assigned instantly, and you can reassign it any time.

Tip

For a perfect beat drop, use the virtual scratch on the platter to cue the first beat by hand, just like on real vinyl. It’s precise, and it’s a genuine DJ skill worth practising.

Pricing

Try the full app free for 24 hours. After that, a single one-time purchase unlocks it permanently — no subscription, ever. All future updates are included at no extra cost.
