 Remote Shutter is a free, open-source iOS app that turns any two Apple devices into a wireless camera system. One device (iPhone or iPad) is the **camera**; the other (iPhone, iPad, Apple Watch, or Apple-silicon Mac) is the **remote**, showing a full-screen live preview and controlling the shutter. The devices connect directly over peer-to-peer Wi-Fi — no internet, no Wi-Fi network, no account, no subscription. Photos and videos stay on the devices; nothing is uploaded anywhere.

+description: "Up to four iPhones as cameras, one iPhone as director: every angle live in a grid, one button that starts recording on all of them at the same instant, and clips that come back time-aligned."
+faq:
+  - q: "How many iPhones can record at the same time?"
+    a: "Up to four iPhones as cameras, controlled from a fifth iPhone acting as the director. Two cameras work for free; Pro unlocks four."
+  - q: "Are the videos synchronized?"
+    a: "Yes. One shutter on the director starts and stops recording on every camera at the same instant, and each clip is stamped with alignment metadata so the angles line up in any editor."
+  - q: "Do I need Wi-Fi or an internet connection?"
+    a: "No. The phones connect directly to each other, peer to peer, with no router or network. Keep Wi-Fi and Bluetooth turned on. A shared Wi-Fi network also works and extends the range."
+  - q: "Where do the videos end up?"
+    a: "Each camera records at full resolution to its own photo library, and the footage then collects automatically to the director. Nothing is uploaded to any server."
+  - q: "Can I change frame rate and resolution on all the cameras at once?"
+    a: "Yes. Frame rate (24, 30 or 60 fps), resolution (1080p or 4K), aspect ratio and HDR are set from the director and applied to the rig, and you can tap to focus on any camera's live preview."
+  - q: "Can old iPhones be the cameras?"
+    a: "Yes — any iPhone that runs the current version of Remote Shutter. Spare and older phones make good fixed-angle cameras; the director should be the phone you hold."
+---
+
+If you have more than one iPhone in the house, you already own a multi-camera rig. Install [Remote Shutter](https://apps.apple.com/us/app/remote-shutter/id633274861) on every phone, pick one as the **director**, and the rest become cameras: you see every angle live in a grid on the director, and one button starts and stops recording on all of them at the same instant.
+
+## What multicam does
+
+- **Up to four cameras, one director.** The director connects to each camera directly over peer-to-peer Wi-Fi — no router, no account.
+- **Every angle live.** The director shows a grid of live previews, so you frame each phone before you roll, and tap any tile to see it full screen.
+- **One synced shutter.** Photo or video, the capture fires on every camera at the same instant. No more clapping for sync.
+- **Camera settings from the director.** Frame rate (24/30/60), resolution (1080p/4K), aspect ratio, HDR and tap-to-focus are set from the director, so every phone rolls at the same 24p/4K without walking around to each one.
+- **Footage comes back to you.** Each camera records at full resolution locally, then the clips collect automatically to the director, stamped with alignment metadata so any editor — iMovie, Final Cut, DaVinci Resolve, CapCut — lines the angles up.
+
+Two cameras are free; Pro unlocks four.
+
+## What it is good for
+
+- **Interviews and podcasts** — a wide two-shot plus a close-up on each person, cut between them later.
+- **Music and dance** — one wide, one on hands or feet, one on the face; record a single take and edit the angles.
+- **Sports and skills** — front and side views of a swing, a lift, a trick, captured on the same frame.
+- **Unboxings and tutorials** — an overhead on the table and a face camera, started together.
+- **Events** — put spare phones on tripods around the room and direct from your own.
+
+## How to set it up
+
+1. Install Remote Shutter on every iPhone and open it on all of them. They find each other automatically — keep Wi-Fi and Bluetooth on; no network is needed.
+2. On the phone you will hold, choose **remote**. When two or more cameras connect, the director grid appears.
+3. Mount the camera phones (any [tripod or clamp](/gear) works) and frame each angle from the director's live tiles.
+4. Tap the shutter to take a photo on every camera at once, or start recording on all of them. Stop, and the clips collect to the director.
+
+## Tips
+
+- Keep the cameras within about 50 ft (15 m) of the director with line of sight, or put every phone on the same Wi-Fi network for more range.
+- Set focus on each angle before rolling so the cuts match — tap the preview where you want it sharp.
+- Old phones are fine as cameras. The director does the most work, so use your newest phone for that.
+- Turn on camera standby on the camera phones for long shoots — the screen rests while the phone keeps streaming and recording.
+
+Single camera is still the everyday case — a [spare iPhone as a remote camera](/blog/use-old-iphone-as-remote-camera) or an [iPad or Mac as the monitor](/blog/iphone-as-second-camera-mac-monitor) — and multicam is the same app with more phones connected.
