Duet Display is how I turn an iPad with a keyboard into a small remote terminal for the two laptops that run my coding work. Sidecar is better for using a nearby iPad as another Mac display, while Jump Desktop and Screens are stronger general remote-desktop comparisons; Duet wins for me because the second-screen and remote-access jobs live in one familiar app.
Why the iPad is the right remote client for me
The iPad is light, has a good screen, wakes quickly, and becomes a convincing mini laptop when I attach a keyboard. I do not need it to become the machine that builds the software. I need it to give me an interactive window into the laptops that already have the repositories, credentials, agents, and local state.
That distinction keeps the setup simple. The laptops remain the hosts. Duet carries display and input to the iPad. I can inspect an agent, answer a prompt, or make a small change without migrating the development environment onto iPadOS or carrying both coding laptops everywhere.
The arrangement also matches the way I keep those hosts available. Amphetamine keeps the Macs awake while Duet supplies the visual interface when I need the whole desktop rather than a purpose-built mobile agent app.
Duet Display vs Sidecar and remote desktop apps
| Option | Best at | Boundary |
|---|---|---|
| Duet Display | Using an iPad as a wired or wireless display and reaching a remote computer | A paid product and account relationship rather than an Apple-only built-in feature |
| Apple Sidecar | Extending or mirroring a nearby Mac onto an iPad inside the Apple ecosystem | Designed for proximity, not as my away-from-home remote desktop |
| Jump Desktop | A dedicated cross-platform remote desktop with mature remote-control features | Does not center the second-display workflow that first made Duet useful to me |
Screens belongs in the same dedicated remote-desktop category as Jump. Either may be the better purchase if remote administration is the only requirement. Duet is unusually coherent when an iPad alternates between being physically beside a laptop and reaching that laptop from somewhere else.
Remote desktop is not the same as a VPN
Duet gives me pixels and input. It is not a general private network, an exit node, or a way for every iPad app to appear on the internet from my home connection. Those are the jobs I compare in Periscope vs Tailscale. The products can complement each other, but calling them interchangeable hides the most important design choice.
For my actual task, I want the entire existing laptop in front of me. Duet makes that possible without pretending the iPad itself is now the coding workstation. That is a narrow promise, and it is why the setup keeps working.

Product details were checked against the following first-party pages on August 28, 2026. My workflow judgments are based on the experience described above.
- Duet Display: supported host and client platforms, second-display modes, and remote access
- Apple Sidecar requirements: the nearby Apple-native display comparison
- Jump Desktop: the dedicated cross-platform remote-desktop comparison
- Screens: another remote Mac and PC client for Apple devices
