CueStack 1.0 is on the App Store. Mark cue points on your audio, replay any section on demand, and time your show without fighting your tools.
The free version covers marking and replay in one project with up to three tracks. The Full Version, a one-time $39.99 unlock, adds SMPTE/LTC timecode (read a striped track or generate your own), OSC and MIDI show control in both directions, dedicated audio routing for separate music and timecode outputs, setlists, unlimited projects and tracks, and project export and import.
Thanks to everyone who ran the TestFlight beta at real shows and filed the reports that shaped 1.0.
