What to Consider

Luna Display is a popular pick for turning an iPad (or another Mac) into a responsive second screen for your Mac, with a hardware-dongle approach that emphasizes performance and a “native display” feel. The alternatives landscape splits quickly: Duet Display competes most directly on the second-monitor job, but with a software-first, cross-platform angle (including Windows and Android), while tools like Bezel, PhoneCast, and Replica focus on the reverse workflow—mirroring iPhone/iPad screens to a Mac or even a browser for demos, recording, and presentations. AirDroid 3 sits further out as a broader device-management suite that happens to include screen-receiver capabilities, which can be appealing if you want an all-in-one control hub rather than a dedicated extended-desktop tool.

In evaluating these options, we looked at core workflow fit (true desktop extension vs mirroring/casting), platform and device coverage, reliability and day-to-day performance signals (where reviews were available), setup friction, and value model (hardware one-time purchase vs software subscriptions/universal purchase), alongside pro features like multi-device support and presentation/recording polish.

Duet Display takes a software-first approach to turning a tablet or phone into an extra screen, which can be a simpler fit than a dongle-based setup like Luna Display. It’s particularly compelling in mixed environments because it supports not just Mac, but also Windows, and works with iPad/iPhone as well as Android devices.

Where Duet stands out is breadth plus control: it’s positioned for people who use a second-screen workflow daily and want more configuration than the built-in options. That “pro-grade” angle matters if Sidecar has been inconsistent, or if you need knobs for performance and behavior rather than a one-size-fits-all connection.

It can also be the practical choice when hardware ports, adapters, or travel setups make carrying an extra accessory annoying. The trade-off is that cross-platform support can introduce platform-specific quirks (especially on Android), but the upside is far greater flexibility in what devices can serve as your display.

Best for

Best for mixed-OS users who want a flexible, software-only second display across Mac, Windows, iPad, and Android.

Standout features

✓Works across Mac and Windows
✓Supports iOS and Android targets
✓Pro-oriented performance and customization
✓Alternative to Sidecar for daily use

Airdroid 3

Fully access your phone from a PC or Mac

AirDroid 3 is best seen as a device-operations suite rather than a dedicated second-monitor tool like Luna Display. If the real goal is managing multiple phones day to day, it brings remote control, file transfer, and notification handling into a single workflow.

That broader scope can be a major advantage in IT, support, and multi-device setups where the screen is only part of the job. Instead of optimizing for “extend a Mac desktop,” AirDroid helps centralize the tasks that usually require picking up the phone constantly.

It’s also appealing when you occasionally need screen receiving via AirPlay, but don’t want a single-purpose display extender. The trade-off is that it won’t replace Luna’s extended-desktop experience for creative or productivity layouts, but it can replace several device-management utilities at once.

Best for

Ideal for IT, support, and power users who manage iOS and Android devices from a Mac or PC.

Standout features

✓Remote device control workflows
✓File transfer and device management
✓Notification sync to desktop
✓AirPlay receiver capability

Bezel

Mirror any iPhone on your Mac

Bezel is built for the opposite direction of Luna Display: it brings iPhone/iPad (and even Apple TV/Vision Pro) screens onto a Mac for demos, presentations, and recording. That makes it a stronger fit when the priority is showing what’s happening on a device to an audience, not extending macOS onto an iPad.

It differentiates with presentation polish—pixel-perfect device frames, clean backgrounds, and exports that look designed rather than improvised. This is the kind of detail that matters for product marketing, education, sales demos, and app teams who need consistent visuals.

Bezel also shines when you need to show multiple devices at once, which is hard to do cleanly with basic mirroring tools. The trade-off versus Luna is straightforward: it won’t give you extra desktop real estate, but it can make on-screen storytelling dramatically cleaner.

Best for

Best for iOS teams and presenters who need polished, multi-device screen demos and recordings on Mac.

Standout features

✓Device mirroring to Mac
✓Pixel-perfect frames and backgrounds
✓Multi-device display at once
✓Transparent and clean export options

PhoneCast

Mirror iPhone or iPad screen to Mac without wires

Learn more →

PhoneCast focuses on wireless mirroring from iPhone or iPad to a Mac, making it a better match than Luna Display when the goal is quick sharing rather than a second desktop. It’s geared toward real-time scenarios like teaching, walkthroughs, whiteboarding, casual gaming, or showing an app during a call.

A key appeal is reducing friction: no cable, no capture workflow, and less setup overhead when you just need the iOS screen on your computer. That simplicity can be more valuable than an extended-display setup when time-to-share matters more than window management.

Its universal purchase positioning can also be attractive if you use multiple Apple devices and want one license to cover the set. The trade-off is that mirroring isn’t the same as extending your workspace, so it won’t replace Luna for people who need a true second monitor for macOS.

Best for

Ideal for educators, creators, and remote workers who want fast wireless iOS-to-Mac mirroring.

Standout features

✓Wireless iPhone/iPad to Mac mirroring
✓Designed for demos and meetings
✓Real-time viewing for drawing and games
✓Universal purchase across Apple devices

Replica

Mirror your iOS screen on a modern web browser

Learn more →

Replica 3.0 is built around the idea of mirroring iPhone/iPad screens to many kinds of receivers, including a web browser, which is a very different value proposition than Luna Display’s extended-desktop setup. It’s a strong alternative when deployment convenience matters—opening a browser can be easier than installing native apps or configuring device-to-device links.

Because it’s oriented toward casting across ecosystems, it fits conference rooms, classrooms, and mixed-device environments where the target display might not be an Apple device. That flexibility can beat a Mac-centric second-monitor solution when your audience and hardware vary day to day.

Replica is also better aligned with “share this screen now” moments rather than sustained multi-hour productivity as a second monitor. The trade-off is that mirroring and casting don’t provide the same workspace expansion as Luna, but they often win on reach and simplicity.
