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 call

The clearest difference is ads: Trapp at none against STAELLA's shown. Trapp also leads on rating (4.2 vs 3.9) and iOS requirement (9.3 vs 15.0). STAELLA's advantage is review sentiment (45% vs 21%) and update cadence (every 2 months vs every 6 months). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. STAELLA sells 7 in-app purchases, starting at $4.99 per 7 days and Trapp sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Trapp holds the better App Store score, 4.2 against 3.9. Both are backed by a comparable volume of ratings — 1.7K and 3.9K respectively. Written reviews complicate that: 45% of STAELLA's written reviews are positive against 21% of Trapp's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

STAELLA ships an update every 2 months, Trapp every 6 months. Both last shipped on October 29, 2026.
