Dual Screen Sync vs Peekside

"Welcome to Dual Screen Sync! Stream with ease and enjoy a bigger, better experience on your phone."

Peekside puts one screen on another screen, over your own Wi-Fi. An iPhone, iPad, or Mac can send. An iPhone, iPad, or Mac can watch. Every pairing works, so a phone can mirror to another phone just as easily as to a Mac. Nothing is uploaded. There is no server in the middle, no account to create, and no sign-in. The picture goes straight from one device to the other and stops there. Pair once, then tap a device and pick what you want: send your screen, watch theirs, or send captions. Nothing starts until the other person allows it on their device.

The watching device cannot tap, type, or drive the device it is watching. A phone sends its screen or its captions, one or the other, not both in the same session. A Mac can send both at once. This is because screen capture on iPhone and iPad runs in a separate system process that cannot be handed a caption. Protected video appears black. That is the operating system blocking capture, and Peekside does not work around it. Sharing stops when the sending phone locks, and on iPhone and iPad it always starts through Apple's own broadcast picker. Peekside needs two devices on the same Wi-Fi network. It does not work over the internet, by design. Some features need Peekside Pro.
