CUE vs Cantus

Cue is a DJ set planner and visualizer. Use this app to keep track of your mixes in a 3D space and see how you can link tracks together, add notes and search through spotify. Plan your DJ sets visually. Cue lets you map out every track and transition in your mix, so you always know what plays next. See your set in 3D Your tracks live in an interactive 3D space. Each song is a node, each transition is a link. Pinch, rotate, and fly through your mix like a constellation. Set a starting track and watch the flow radiate outward. Build your tracklist Add songs with title, artist, BPM, key, cover art, and personal notes. Search Spotify as you type to auto-fill track details and artwork, or add tracks manually. Link your transitions Connect tracks that mix well together. Add notes to each transition — drop points, EQ tips, whatever helps you remember the blend. Your links become the edges of your set graph. Card view Switch to a clean scrollable setlist that follows your transition chain from start to finish. Linked tracks appear in set order with numbered positions. Unlinked tracks sit in a separate section so you can see what still needs connecting. Open in Spotify Tap any track to open it directly in Spotify. Remind yourself how a song sounds without leaving your workflow. Set your starting track Pin one track as the head of your set. In 3D mode it anchors to the center. In card mode it becomes track number one. Everything flows from there. Built for DJs Cue is not a Dj mixer
