Pair Shutter (interlock shutter camera)

Pair Shutter is a camera app that lets two iPhones control the shutter together, ideal for couples, parties, and group shots. It uses Bluetooth or the same Wi-Fi network to link the shutters and synchronize shooting.

How to use: On the Master iPhone, set a 2-character channel and tap Start. On the Child iPhone, enter the same channel and tap Start. The app supports up to three paired sets. If the camera won't start, check Settings > Privacy > Camera and ensure Pair is enabled.
