MightyMouse vs Astropad Workbench

Both let you reach your Mac from your phone while an agent is still working. What you pay, and what you get besides the screen, is where they split.

Astropad Workbench streams your entire Mac desktop to an iPhone or iPad and lets you drive it from there. It launched in April 2026 aimed squarely at people babysitting long AI agent runs on a Mac they are not sitting at. Astropad have been making iPad-to-Mac software since 2013, so this is a serious product from people who know the problem.

MightyMouse starts from the same place and adds the parts that are not the screen: your iPhone becomes a real trackpad and a microphone, and anything you say is transcribed on your own Mac rather than sent anywhere. It is free if you already pay for Claude, Codex, Gemini or OpenCode.

Where Astropad Workbench is the better pick

If you work from an iPad, pick Workbench. It is built for the big screen and it supports the Apple Pencil for precise cursor work, which is genuinely better than a thumb on glass for anything fiddly. MightyMouse is aimed at an iPhone in your hand.

Reviewers also singled out its unified multi-display view, which collapses every monitor attached to your Mac into one canvas so you no longer need a dummy plug on a headless machine. If you run a Mac mini with three displays, that alone may decide it. Astropad have said Windows and Linux are coming, which would put them somewhere MightyMouse has no plans to go.

Where MightyMouse is the better pick

The first reason is the free plan. Workbench gives you 20 minutes a day before it asks for $14.99 a month. MightyMouse costs nothing at all if you already pay for Claude, Codex, Gemini or OpenCode, and there is no daily clock on it. For checking on an agent five times an evening, twenty minutes disappears quickly.

The second is what happens to your voice. Both let you dictate. Only MightyMouse transcribes on the Mac itself, with Whisper, so the audio never leaves the machine, and only MightyMouse can do something with the words instead of just typing them - select an awkward paragraph and say "make this shorter" and it is replaced where it sits. Astropad do not say where their dictation is processed, so if that matters to you, ask them before you rely on it.

They are solving slightly different problems

Workbench is a remote desktop, in the honest sense: the whole screen, streamed, driven from somewhere else. That is a well-understood job and Astropad do it with their own streaming code built up over a decade of Luna Display and Astropad Studio.

MightyMouse treats the phone as a piece of the computer rather than a window onto it. The screen is there, but so is a trackpad you move with your thumb, a keyboard, and a microphone wired into local transcription. If you mainly want to look at the Mac, either works. If you want to work the Mac, the input side is the difference.

Worth being clear about one thing: reviewers found Workbench sharper and more reliable than we are on the pure streaming job, and Astropad have been at this a lot longer. If flawless picture quality on a big iPad is the whole requirement, they are the safer bet.

What both of them cost you

Neither of these replaces sitting at your Mac. A phone screen is small, a thumb is not a mouse, and both products stream a compressed picture rather than the real thing. Astropad say as much themselves about file transfer, which Workbench does not do. MightyMouse cannot open a file on your phone and drop it onto the Mac either.

If what you actually want is an agent doing the clicking rather than you doing it remotely, that is a different product again - see Anthropic's own Dispatch for that end of it, or Happy Coder if you only ever need the coding session and nothing else on the machine.

Common questions

Do I need an AI subscription?

No. Connect a Claude, Codex, Gemini or OpenCode account you already pay for and MightyMouse costs nothing. Have none? Sign up and use the built in option, no card needed. Voice transcription is free either way because it runs on your Mac.

Is MightyMouse a free Astropad Workbench alternative?

If you already pay for Claude, Codex, Gemini or OpenCode, yes - MightyMouse costs nothing on top and has no daily time limit. Workbench has a free plan capped at 20 minutes a day, then $14.99 a month or $79.99 a year as listed on their site in August 2026. Prices move, so check theirs before deciding.

Does Workbench work on iPhone, or only iPad?

Both, as long as you are on iOS 26 or iPadOS 26 and your Mac is on macOS 15 or later, per their site in August 2026. MightyMouse runs on Apple Silicon and Intel Macs.

Does either one send my voice to a server?

MightyMouse does not. Transcription runs on your Mac with Whisper and the audio stays there. Astropad do not say publicly where Workbench processes dictation, so we are not going to guess on their behalf - it is a fair question to put to them.

Can I use my iPad with MightyMouse?

It works, but it is built for an iPhone in one hand. If the iPad is your main screen and you want Apple Pencil precision, Workbench is the better fit and we would rather say so.

Want the screen and the input side without a subscription? MightyMouse puts your Mac on your iPhone as a screen, trackpad and microphone, and transcribes your voice on your own machine for free.
