Free core featureSurround Display by Peaceful Journey
Turn an unused iPad into a display and speaker
Give a spare iPad a useful place beside your Mac. Use it as an extended display and its built-in speakers for stereo, or assign distinct synchronized channels across multiple receivers. Choose display only, speaker only, or display + speaker. First-time pairing requires a six-digit code and receiver approval.
The public Mac packages are Universal 2 Build 10 releases that passed Developer ID signing, Apple notarization, stapling, and Gatekeeper verification. The iPhone and iPad receiver is distributed separately through App Store review.
Reuse what you already own
Give a sleeping iPad
a new place to work
Before buying another monitor or wireless speaker, place an iPad you already own beside your Mac. One receiver can add workspace and stereo playback; two can become left and right displays with distinct synchronized channels.
- Display onlyExtra room for documents, web pages, and tools
- Speaker onlyA full-screen speaker skin with built-in speaker playback
- Display + speakerBoth roles together on the same iPad
Speaker playback is an optional one-time purchase. Stereo input is labeled Stereo Upmix—not Dolby, Atmos, or restoration of an original 5.1 mix.
Release status
Only verified apps and installers are published
The Mac controller is named Surround Display. The separate app that turns another Mac into a receiver is named Surround Display Receiver. Both public ZIPs passed Developer ID signing, Apple notarization, and Gatekeeper verification.

Release status · August 21, 2026: iPhone and iPad receiver 0.1.0 Build 10 is ready for submission in App Store Connect. The Mac controller and Mac receiver are published as Universal 2 packages named Surround Display and Surround Display Receiver after Developer ID signing, Apple notarization, stapling, and Gatekeeper verification.
Three connection modes
Connect only the roles you need
Display and audio roles are separate. Speaker-only mode is designed not to start video capture or transmission resources.
Speaker only
Use a selected device for stereo or one synchronized channel without video resources, with the chosen speaker skin and volume controls filling the display.
Requires Surround SpeakerDisplay + speaker
Use one receiver for an extended display and a speaker channel on a shared media timeline.
Display and audio togetherSynchronized speakers
Assign a distinct channel to each device
Mirroring the same audio and distributing separate surround channels are different modes. The system is being built around scheduled future playback times and measured output skew, not simultaneous packet delivery alone.
One device · stereo
Play both left and right channels through one device's built-in speakers.
Two outputs · left/right
Assign Front Left and Front Right to two output nodes.
Three outputs · Beta
Suggest Front Left, Center, and Front Right while physical-device validation remains beta.
Four outputs · Beta
Suggest Front Left, Front Right, Surround Left, and Surround Right.
Stereo expansion
A stereo source uses matrix-based Stereo Upmix. It is never labeled Dolby, Atmos, or restored original 5.1.
Scheduled playback
Account for network, buffering, and output latency and track long-running clock drift.
Current product boundary
Using the Mac speaker as an independent fifth channel, preserving Native Multichannel input, and automatic room correction remain experimental. We will not advertise completed 5.0 until those paths pass physical acoustic validation.
Speaker-only surface
Keep acoustic material and control style independent
Changing a skin does not force a new volume interface, and changing the control style does not replace the selected material EQ or room correction.
Black Ebony
A dense, controlled material-inspired character with short, weighty motion.
Silver Aluminum
A fast, precise character with machined reflections and transient response.
Brown Paulownia
A warm, natural character with softer driver movement.
Transparent Internal
A reference-oriented skin that reacts only at model-specific internal speaker positions—without a virtual woofer.
Choose your volume control
A rotary dial, 5% step buttons, and continuous slider all control the same authenticated group gain.
Quick group mute
Tap once for 0%; tap again to restore the previous group volume. This remains separate from muting only this iPad.

Purchase and control boundary: Purchase and restore occur only in the iPad or iPhone App Store receiver. The Mac provides the controls, but enables speaker, skin, and EQ commands only after the connected receiver passes StoreKit verification and reports access for the current authenticated session. A local preference or Mac command alone can never unlock a paid feature.
Audio remains fixed to Flat EQ while the EQ & Speaker Skin Pack is locked. Branded skins and confidential EQ profiles will be added only after separate agreements and validation.
Connection security
Sharing a network never grants access
Wi-Fi, Ethernet, USB, and Thunderbolt paths use the same user-authentication boundary.
Discover
Find nearby receivers only through the connection policies the user selected.
Verify six digits once
Confirm the code shown only on the receiver and approve the connection there.
Choose a trust period
The user controls trusted-device reconnection and can revoke trust at any time.
Local-first data boundary
- Display, audio, and input traffic travels over an encrypted local connection between authenticated devices and is not uploaded to Peaceful Journey servers.
- Session, device, packet, and sequence identifiers are validated; stale or malformed packets are dropped.
- A receiver-initiated disconnect suppresses automatic reconnection until the user requests it again.
- Camera or microphone calibration starts only after user action; raw video and voice are not stored on our servers.
Compatibility and permissions
Surround Display and receiver roles stay explicit
The Mac controller requires macOS 15 or later. The receiver supports iOS/iPadOS 15 or later; versions 15–17 use a reduced display and built-in-speaker interface, while QR, advanced calibration, and remote input require version 18 or later.
Surround Display
The free controller app on the host Mac captures display and system audio and coordinates the session.
- Finder name: Surround Display
- Screen & System Audio Recording
- Local Network
- Accessibility when touch input is enabled
iPad and iPhone receiver
Receives a display, direct touch, and an assigned speaker channel.
- Local Network
- Audio playback and optional background playback
- Camera and microphone only for calibration
Surround Display Receiver
The separate receiver app uses an iMac, Mac mini, or another Mac as a secondary display.
- Finder name: Surround Display Receiver
- Ethernet, Thunderbolt Bridge, or Wi-Fi
- On-device approval
| Area | Current policy |
|---|---|
| Mac keyboard and mouse | Uses the normal macOS extended-desktop path and must pass click and keyboard regression tests before release. |
| Direct iPhone or iPad touch | Pointer movement, left-click, and drag remain under release validation. |
| Receiver count | One or two receivers are the primary validation range; three or four require explicit Beta opt-in. |
| Audio route | Built-in and wired output are preferred. Bluetooth and AirPlay re-output are warning or initially unsupported routes. |
Camera-assisted layout, microphone-based acoustic measurement, and three- or four-device sessions are experimental or beta. A successful packet transfer alone does not count as a working display, input, or synchronized speaker.

Can I use Cat 8 Ethernet and a USB hub?
Yes, with an Ethernet adapter recognized by the operating system and a properly powered hub. Throughput is limited by the slowest adapter, hub, or network port.
Is display or audio content stored on an external server?
Active display, audio, and input traffic travels over an authenticated encrypted local path and is not uploaded to Peaceful Journey servers. See the privacy policy for details.
