Real-time music visualization. 30 Visuals × 78 Shapes — every play, a different piece. ■ Design the visuals from a free combination 4 categories with 30 Visuals and 78 Shapes, Knobs, Text, backgrounds, 10 Screen Effects and 10 Wallpaper Blends. Layer them into anything from a club-style spectrum to an ambient nebula. Visuals and Shapes switch on the beat of the song. On HDR displays, glows and gradients render with brightness beyond SDR. ■ Preset sharing Save the look you made as a preset and share it with a code or a link. ■ Two recording modes for different intents Recording keeps every knob move and Visual switch you make. Export locks the UI so a stable, hands-off render finishes on its own. Before exporting, you can also edit the show along the flow of the song, like in a video editor. Both hide the UI, support up to 4K with HDR export, and can auto-record a full song in Playlist mode. ■ Four audio sources Files (music on device; iOS also imports from the iTunes library) Microphone (low-latency input) Simulation (visuals keep moving with no source) AUv3 (visualize plugin audio) ▸ Time-synced lyrics Songs available in a supported lyric database can display lyrics in time with the music. Song title and artist name too. You can also show lyrics you typed yourself. ▸ External display output (AirPlay / HDMI adapters) Connect a TV or projector via iOS Screen Mirroring (AirPlay) or an HDMI adapter. The visuals go full screen while the UI stays on your device. ■ Play with whatever's in your hand Touch and flick iPad + Magic Keyboard shortcuts MIDI controllers (long-press any knob to assign, BLE MIDI supported) Gamepad (D-pad, buttons, sticks) ■ Where to use it · VJ sets at clubs, live shows and streams · Music videos and lyric videos for social · Screen visuals for a room or a party ■ Notes · DRM-protected tracks (e.g. Apple Music) can't be played. · For issues or requests, reach out via in-app feedback or support.

Verdict
The clearest difference is in-app purchases: 531player at none against STAELLA's 7. 531player also leads on ads (none vs shown). STAELLA's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price there is nothing between them.
