How to sync movies between your iPhone and a Mac, laptop or desktop
Watching on your phone while your partner or friend watches on their MacBook or PC? Watchly keeps both screens in perfect sync. Install the Chrome extension on the computer first, then grab the app on your iPhone, and press play together.

Quick answer
To sync movies between your iPhone and a Mac, laptop or desktop, use Watchly on both devices and join the same room. The fastest setup is: (1) on the computer, install the Watchly Chrome extension and create a room; (2) on your iPhone, download the Watchly app and open the same room link; (3) sign into your own streaming account on each device and press play — Watchly keeps both screens frame-accurate, with live chat and voice alongside.
This works because Watchly runs natively on both surfaces: a real iPhone app and a Chrome extension for Mac, Windows and Linux desktops. So the person on the couch with their phone and the person at a laptop watch the exact same moment together, in sync — free for Netflix, Prime Video, YouTube and SoundCloud (HBO Max on Pro).
Sync your iPhone and computer in 3 steps
Set up the desktop Chrome extension first, then the phone app — then join one room.
1. Install the Chrome extension on your Mac or desktop
On the MacBook, laptop or desktop, open Chrome and add the free Watchly extension from the Chrome Web Store. Pin it, sign in, and create a room — you'll get a shareable room link. The extension is what lets a computer join a Watchly watch party, since desktop browsers (unlike phones) run extensions.
2. Download the Watchly app on your iPhone
On your iPhone, install Watchly from the App Store (it's on Android too). Open the app and either create the room yourself or paste the link from the computer. Phones can't run Chrome extensions, so the native app is how your iPhone joins the same synced room.
3. Join the same room and press play together
Open the same room on both devices, sign into your own streaming account on each, and pick a title. When anyone hits play, pause or seek, it happens on both the iPhone and the computer at the same instant — with live chat and push-to-talk voice next to the video.
Why you need both the extension and the app
The reason most "watch party" tools fail at phone-to-laptop sync is that they only ship one surface. Teleparty, Scener and Watch2Gether are built around a desktop Chrome extension — great on a MacBook, useless on an iPhone, because iOS Safari and Chrome don't support extensions. Apple SharePlay is the opposite: lovely on iPhone and Mac, but Apple-only and limited to apps that opted in. Neither cleanly covers one person on a phone, one person on a computer.
Watchly is designed for exactly that split. It runs as a native iPhone and Android app and as a Chrome extension on Mac, Windows and Linux, and both join the same Watchly room. That's what makes true cross-device sync possible: your phone and the laptop are equal participants in one room, not one screen mirroring another.
Do we each need our own subscription?
Yes. Like every legitimate watch party tool, Watchly syncs each viewer's own streaming login rather than broadcasting one screen — so each person (and each device) signs into their own Netflix, Prime Video or HBO Max account. That keeps full HD quality on every screen and stays within the streaming services' terms. Watching Netflix, Prime Video, YouTube and SoundCloud together is free; HBO Max and extras like no ads and unlimited room members are on Watchly Pro.
Tips for the smoothest phone-to-desktop sync
- Create the room on whichever device is easiest — the desktop extension or the iPhone app can both host. Share the room link to bring the other device in.
- Use a stable connection on both ends. Sync commands are tiny, but a weak Wi-Fi signal on the phone or laptop can cause brief drift; a quick pause-and-resume snaps everyone back together.
- Sign in before you press play. Make sure the phone and the computer are each logged into the streaming service first, so nobody hits a login wall mid-scene.
- Turn on voice. Push-to-talk voice sits right next to the video, so the person on the couch and the person at the desk can react together in real time.
The same room-and-link flow works for any pairing of devices — two phones, phone and laptop, or two laptops across the world.
