Not a phone app. The screen department.
Five categories, 67 fictional device kinds — every one original, cleared UI you can point a lens at. If a scene puts a glowing rectangle in frame, it’s in the kit.
Phone & handhelds
Calls, texts, notifications, home screens, feed, maps, wallet, email — and green screen for VFX.
Screens & readers
Desktop OS, smart-TV launcher, e-reader, handheld game, jukebox, digital picture frame.
Signage & boards
Billboards, airport departures, menu boards, weather radar, scoreboards, stock ticker, flip clocks.
Kiosks & payment
ATM, card terminal, vending, parking meter, fuel pump, ticket kiosk — plus casino, roulette and poker.
Instruments & monitors
Car dash, live-ECG vitals monitor, CCTV grid, drone HUD, sonar, spaceship console, dashcam, seismograph.

Every one of these renders in the browser — the same engine that drives the phone, on an oscilloscope, a vitals monitor, a car dash…

Why Glass Double
Every device on set
One shared engine renders on web, Android and iOS — the prop can be the phone in frame or a browser on a tablet.
Fictional by default
Original OS + app skins, all original assets. Nothing on screen is real Apple or Google UI, so there's no real-brand interface to clear.
The full prop kit
Call screens, video calls, scripted messages, notification stacks, home screens, and green-screen tracking.
Made by crew
One-button on-set controls, hardware cueing, works offline. Built for prop masters, playback ops and indie crews.
The most-shot screen, in full.
Phones are in most scenes, so they get the deepest kit — parity with the on-set apps productions already use, rebuilt cross-platform and clearance-friendly. Every other device kind works the same way.
Call screens
Incoming & active voice/video calls with custom contacts and states.
Messages
Scripted threads that play back on cue, timed for actor delivery.
Notifications
Stackable lock-screen and banner notifications that tell a story.
Home screens
Fictional home layouts and app grids, fully themeable.
Green screen
Chroma fills with built-in registration markers for VFX.
Fictional OS skins
Swap the whole device look — Lumen, Verge and more.
Cue the hero device without touching it.
Glass Double isn’t a mockup generator — it’s a playback system. Drive the screen that’s actually in the shot from a second device, so no actor or PA has to reach into frame. Build a cue sheet ahead of the take and step it live. In a signal dead zone, pair the two devices directly — peer-to-peer over a set hotspot, no internet and no server — and every take is snapshotted so you can roll back between setups.
Present
Run the prop on the device that's actually in frame — full-screen, no browser chrome, edge-to-edge on real hardware.
On-Set
The device fills the screen and waits, camera-clean: no cursor, no notifications of its own, screen kept awake for the length of a take.
Operator
From a second device, ring the incoming call, reveal the next scripted text and fire notifications on your mark — one GO button, hands-free. Cue over the network, or pair the two devices directly with no internet at all.
Made for the whole unit.
A prop screen touches half the floor — the art department that builds it, the op who cues it, the editor who cuts it and the producer who has to clear it. Glass Double is built for each of them.
Prop & art dept
Build screen-accurate props for phones, monitors, dashboards, ATMs and billboards — 67 device kinds on a fictional OS.
Playback op
Cue calls, texts and notifications live from the Operator console — on the button, take after take, on or off signal.
VTR / DIT
Present and On-Set run full-screen and offline, so nothing real-brand is ever on camera in the set dead zone.
Editorial
Alpha PNG sequences and ProRes 4444 drop straight into Avid, Resolve, Premiere and After Effects.
Director
See what the audience will — the real screen content, live in the frame, not a slate to replace in post.
Producer & counsel
A per-shot clearance log and a filable insurer attestation for every device you shot.
Swap the whole device. Try it.
Pick a screen, an operating system, and a device — the same engine renders any prop on any skin, on phone, tablet or watch, live, with no rebuild and no real-brand exposure.
Home · Lumen — Lumen OS
…and that’s just the phones. Seventeen skins across phone, tablet and watch:
Realism is the liability we solve — not the thing we sell.
Real iOS and Android UI, app icons and logos are protected by trademark and trade dress. Show them without a deal and you’ve bought errors-and-omissions (E&O) exposure that can hold up delivery. Glass Double keeps all of it off camera — everything on screen is original, fictional UI. But cleared pixels aren’t the whole job: Glass Double keeps an append-only record of exactly what was on every shot’s screen — which fictional skin, which assets, who signed off, and when.
Per-shot clearance log
A printable, per-shot record of the fictional skin + assets used on each device.
Project clearance report
A one-page report across the whole project, ready for delivery and QC.
Insurer attestation letter
A formal, filable E&O attestation you can hand your production's counsel and insurer.
Glass Double removes real-brand UI from the shot and documents what you used. Final clearance and E&O sign-off — including anything you add, like names, logos, likenesses or music — still rest with your production and counsel.
Straight answers
Why not just use a real phone in airplane mode?
Two reasons. Airplane mode hides the signal, not the brand — the camera is still pointed at real iOS or Android UI, which is the part that creates E&O exposure. And you're still relying on a crew member off-camera to land an incoming call exactly on action. Glass Double puts original, fictional UI on screen and lets you fire the cue on the button, take after take.
How does the clearance side actually work?
Every module renders original, fictional UI on fictional-OS skins — no real trademarks or trade dress — and each prop keeps a per-shot E&O clearance log you can export as a PDF. It keeps real-brand UI off camera, but final clearance sign-off still rests with your production and counsel.
Does it work offline on set?
Yes. Present / On-Set mode works offline, so you can cue calls, texts, and notifications from the Operator console at locations with no signal. Cloud sync catches up whenever you're back online.
What formats can I hand to editorial?
Export a numbered alpha PNG image sequence that imports into Avid, Resolve, Premiere, and After Effects, plus alpha WebM, plain WebM, PNG stills, a contact sheet, and the clearance PDF — all at your chosen fps and resolution.
Web, iOS, or Android?
One shared engine renders on web, iOS, and Android, so the prop can be the phone the camera sees or a browser on a tablet. Present / On-Set mode runs on any tablet for the playback op.
Can a whole crew collaborate?
Yes. Props live in cloud projects with real-time collaboration and version history, so prop masters, playback ops, and editorial all work from the same source of truth across devices.
Can I match a specific device?
Pick from real device frames — phones with a notch, Dynamic Island, or punch-hole, plus tablet and watch shells — so the prop reads as the exact hardware your scene calls for, without any real on-screen brand UI.
