Mark the moment.
Replay it on cue.
CueStack is an iPad app for marking cue points on an audio track and replaying sections on demand — built for video programmers and live-event operators who loop a moment while timing the show. On-device, no accounts.

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.
Three steps
Import a track
Files, iCloud Drive, USB, or drag-and-drop. mp3, wav, m4a, aac, aiff, flac — anything iPadOS can decode.
Mark typed cues
Tap the waveform to drop a cue; give it a type, color, shape, and an optional note.
Tap to replay
Tap a cue to jump and play; flip on loop mode to re-arm the section hands-free.
The editor on iPad
Waveform, time ruler, typed markers, and the cue list together.

Five cue types, color-coded
