StageLight is a professional lighting control app for the iPad based on Art-Net (DMX512 over IP). The software combines the classic hardware lighting console feeling with a modern and intuitive user interaction design. The user interface is characterized by intelligent use of available space in combination with a high level of flexibility. MULTIPLE UNIVERSES Manage and control fixtures and groups across up to 10 DMX universes. FIXTURE LIBRARY StageLight offers an extensive fixture library based on the Open Fixture Library. New additions include GDTF file import, continued support for StageLight legacy fixtures, and a fixture editor for creating and customizing your own fixtures. MIDI Connect a MIDI controller and turn StageLight into a hardware-style lighting console, or synchronize cue lists with your preferred DAW. CONTROL CHANNELS StageLight is fixture-based. You can assign a single device, a group, or a cue list to a channel across up to 200 pages. IMPORT AND EXPORT Import and export projects or custom fixtures. Project export supports selectable options for fixture patching, cue lists / effects, and settings. Additional print exports are available, including patch sheets, fixture labels, and fixture lists. Use any sharing service such as iCloud, Dropbox, or AirDrop to share projects with friends, colleagues, or between different iPads. CUES AND CUE LISTS Record cues and play them back in cue lists as sequences or chases. Various trigger and sync options are supported, including Global BPM, Ableton Link, and MIDI Clock. EFFECTS Effects in StageLight enable dynamic lighting transitions directly inside cue lists. This allows you to combine static scenes with moving or rhythm-based effects to create more vivid and flexible shows. ABLETON LINK Ableton Link is a technology that synchronizes beat, phase, and tempo between Ableton Live and other Link-enabled applications (DAWs) over the network. In StageLight, Ableton Link is used to synchronize chaser tempo. CITP StageLight uses the Controller Interface Transport Protocol (CITP) to record cues, retrieve thumbnails, and select fixtures in Capture. OSC In StageLight, you can use the Open Sound Control (OSC) protocol to control supported devices with OSC commands. CRMX & W-DMX StageLight supports LumenRadio's Bluetooth DMX protocol, enabling communication with all LumenRadio and OEM products. STAGELIGHT API The StageLight API allows external control of key functions such as cue lists, fixture channels, and tempo. It is relevant for integrations with Companion and Stream Deck and extends StageLight with flexible connectivity to external control systems.

Verdict
The clearest difference is rating: Duet Display at 4.4 against StageLight's 3.8. Duet Display also leads on ratings volume (49K vs 8) and device support (4 vs 1). StageLight's advantage is review sentiment (84% vs 45%) and ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Duet Display sells 6 in-app purchases, starting at $3.99 per month and StageLight sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Duet Display holds the better App Store score, 4.4 against 3.8. That said, the two scores are not equally well evidenced: Duet Display has 49K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 45% of Duet Display's written reviews are positive against 84% of StageLight's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on October 18, 2026 and October 9, 2026 respectively.
