Quik Tracks
iOS app for firing sound effects and backing tracks live
At a glance
I designed and launched Quik Tracks for OneGenius, an iOS app that lets performers and DJs start and stop sound effects and backing tracks on cue. It was used by top country acts Florida Georgia Line and Keith Urban.
The challenge
Live performers and mobile DJs needed to fire sound effects and full backing tracks exactly when they needed them, and to set everything up in seconds.
What I led
- Took the app from concept to launch on the App Store
- Designed a simple, colorful grid of track buttons that start and stop with one tap
- Made setup fast enough to finish in seconds before a show
- Worked through research, wireframes, prototypes, interaction and visual design
The outcome
Quik Tracks launched on iOS and was used by Florida Georgia Line, Keith Urban, multiple radio stations across the country and many others.
Overview
Quik Tracks was designed with the music user in mind. It was created for everyone from live concerts to mobile DJs who need sound effects or full backing tracks that start and stop exactly when they need them to.
Client OneGenius asked for a UX that was simple and colorful, so users could see and set up everything in seconds.

Final observations
Designing for a live stage meant big targets, bold color and zero guesswork. That simplicity is why performers like Florida Georgia Line and Keith Urban could rely on it.
