How to use your iPhone as a trackpad for your Mac
Your Mac trackpad just died, or you are three feet from your desk and do not want to walk over. Your iPhone is right there. Apple gives you no way to use it as a trackpad.
Short answer: Apple has no built in way to use an iPhone as a Mac trackpad, since Sidecar and Universal Control only work with an iPad. The real options are a trackpad app from the App Store such as Remote Mouse or Remote Trackpad, or MightyMouse, which serves a trackpad page to Safari after you scan a QR code and needs no app install.
Search for this and you will land on old how-tos pointing at Universal Control or Sidecar, as if one setting turns your phone into a trackpad. It does not, and it never has. Worth separating the two things people actually want, because they get answered differently.
Why Apple has no built in answer
Sidecar lets you use an iPad as a second display for your Mac, with Apple Pencil support. Universal Control lets one keyboard and trackpad move across a Mac and an iPad sitting next to each other. Apple's own support page is explicit that both are Mac-and-iPad features: Universal Control "works exclusively with Mac and iPad devices" and points iPhone users at a different feature, iPhone Mirroring, for the opposite direction: seeing your iPhone on your Mac, not using your iPhone to drive your Mac.
So there is no hidden setting. An iPhone was never on either feature's supported list, and nothing in a recent macOS or iOS update changes that. If your iPhone is going to act as a trackpad, it needs an app that builds the connection from scratch.
The App Store options
Remote Mouse turns your iPhone into a trackpad, keyboard and media remote, connecting over Wi-Fi or Bluetooth by their own App Store listing, which as of September 2026 also shows a Pro subscription (from about $13.99 a year) for features like the media panel and Bluetooth, and reviews describing dropped Wi-Fi reconnects after the phone locks.
Remote Trackpad: Virtual Tool is built specifically to be "two in one, keyboard and trackpad," per its own listing, which as of September 2026 states it needs your iPhone and Mac "connected to the same Wi-Fi network" and prices a subscription at $6.99 a week or $9.99 for three months. Its own reviews flag a real gap worth knowing before you install it: no reliable way to click-and-drag.
Both need a companion piece installed on the Mac side too, either a small server app or a system extension, and both ask for a subscription past a short trial. That is a reasonable trade if you already know the app and like it. It is also exactly what a lot of people are trying to avoid when the actual job is a five-minute fix for a dead trackpad, and it means downloading something to two devices before you even know if the gestures feel right.
None of that makes Remote Mouse or Remote Trackpad bad apps. Both have been around for years, and either is a fine choice if a subscription does not bother you and you are happy installing a helper app on the Mac. The tradeoff is simply that "use your iPhone as a trackpad" now means two installs and a recurring charge, for something that used to just be built into the computer.
The option with no app to install: MightyMouse
MightyMouse turns your iPhone into a trackpad, keyboard and mic for your Mac by serving the control page straight from the Mac to Safari. There is nothing to install on the phone and nothing in the App Store to find.
- Open MightyMouse on your Mac and go to Settings.
- A QR code appears. Open your iPhone camera and point it at the code.
- Tap the notification. Safari opens a page with a trackpad and a mic button.
- Drag to move the cursor, tap to click. You are controlling the Mac.
That QR code carries a one-time pairing code your phone trades for a credential it keeps, so every connection after the first one is automatic. Nobody else on the network can point a browser at a guessed address and get in.
The gestures that matter
The trackpad matches a real Mac trackpad closely enough that your hands already know it:
- Move the cursor. One finger, drag.
- Click. One finger, tap.
- Double-click. One finger, double-tap.
- Click and drag. One finger, hold, then drag - this is the gesture Remote Trackpad reviewers said they could not find.
- Right-click. Two fingers, tap.
- Scroll. Two fingers, drag.
A full on-screen keyboard sits alongside the trackpad, mirroring your Mac's actual key layout rather than a generic one, so shortcuts land where you expect them. There is also an app switcher gesture for moving between open windows without reaching for the Mac at all, which matters more than it sounds once you are actually working from the phone instead of just nudging a cursor for thirty seconds.
The headless Mac mini case
If your Mac has no monitor attached at all, this still works, because the phone is not asking the Mac for a video signal the way a physical display does. It is capturing the screen in software and streaming it to the phone, so a Mac mini tucked under a desk with no display plugged in is a completely normal setup.
The one condition that actually matters is whether the Mac is awake. A sleeping Mac stops offering its screen to any capture at all, on every remote tool, because macOS itself tears down the display the moment it sleeps rather than just dimming it. MightyMouse has an Away Mode that keeps the Mac from sleeping while you are working it remotely and covers the real screen with a plain curtain so nobody walking past sees your desktop, which is what makes a headless Mac mini practically reachable rather than reachable only when someone is standing next to it.
Latency, Wi-Fi and what happens away from home
On your own Wi-Fi, control is free and unlimited on every plan, and cursor movement is fast enough for real work, not a demo. Leave the house and it keeps working over cellular, switching to a Cloudflare tunnel instead of your home network, with a free monthly allowance for that part. Once that allowance is used up in a given month, the control page still works, it just falls back to a plainer connection path rather than cutting you off.
Every trackpad app in this article, including MightyMouse, needs some network path between phone and Mac. None of them work if the Mac has no network connection at all, and none of them beat a wired trackpad for raw responsiveness at the desk - there is a small amount of lag no matter how good the connection is, because the tap has to travel from your phone to your Mac and the picture has to travel back. On the same Wi-Fi it is small enough to ignore. Over cellular on a weak signal it is noticeable, which is normal for any tool making the same round trip. The honest reason to reach for any of these is being away from the machine, not replacing the trackpad you already like.
When a trackpad app is not what you actually need
If your Mac trackpad works fine and you are sitting in front of it, none of this is worth setting up - use the trackpad. If you want an iPad as a real second monitor with Apple Pencil support, that is Sidecar, which is an iPad feature, not an iPhone one. And if the trackpad is one piece of a bigger want, checking on a long build or an agent from another room, driving the whole Mac from your phone covers more ground than a trackpad app alone.
Your iPhone as a real trackpad and keyboard for your Mac.
No app to install. No card to try it.
Common questions
Can I use my iPhone as a trackpad for my Mac without an app?
Yes, with MightyMouse. It runs on the Mac and serves the trackpad page to your iPhone's Safari browser after a one-time QR code scan, so nothing installs on the phone itself.
Does Universal Control work with iPhone?
No. Apple's own support page states Universal Control works with Mac and iPad only. There is no setting that adds iPhone support.
Why does my iPhone trackpad app need the same Wi-Fi network?
Most App Store trackpad apps only connect over your local network, so the phone and Mac have to share the same Wi-Fi. Tools built around a tunnel, like MightyMouse, can also work over cellular away from home.
Can I use my iPhone as a trackpad for a Mac mini with no monitor?
Yes, as long as the Mac is awake. The remote screen is captured in software rather than read off a physical display, so no monitor needs to be plugged in - the Mac just cannot be asleep when you connect.
Is there a free way to use an iPhone as a Mac trackpad?
MightyMouse's trackpad and keyboard are free and unlimited on your own Wi-Fi. The App Store alternatives are typically free to try with a paid subscription for full features.
For the trackpad plus everything else you would want from your desk: MightyMouse turns your iPhone into a trackpad, keyboard and mic for your Mac, free on your own network.
