Mark the moment.
Replay it on cue.

CueStack is an iPad app for marking cues on an audio track and replaying any section on demand. Built for video programmers and live-event operators who need to loop a moment while timing the show.

iPad-only, iPadOS 17+. No accounts, no cloud, no network required.

The CueStack editor on iPad: a waveform with typed cue markers, the cue list, and the large timecode readout.

An on-device cue editor for iPad

Drop an audio track into CueStack and you get a full-height waveform you can pinch to zoom and tap to seek. Mark the spots that matter (a downbeat, a hit, a transition) and tag each with a cue type that carries its own color and shape.

Everything stays on the iPad. No accounts, no cloud, no network required. Your tracks and cues live on the device.

Color and icon, at a glance

Every cue type carries a color and an icon, so one glance at the timeline tells you what each marker is. Five types are built in. Make your own, and tag any cue with an icon from an expanding set for lighting, sound, video, FX, and more.
