## What is PeerClock Metronome?

PeerClock Metronome is a P2P-synchronized metronome for Apple devices.

Just connect multiple devices to the same Wi-Fi — no server needed. All devices automatically discover each other and sync their clocks with ±2ms precision using NTP-style 4-timestamp exchange.

Features:
• Peer-to-peer — no master/slave, every device is equal
• ±2ms clock synchronization
• Wi-Fi only — no external server, no internet required
• Auto-discovery — connect to the same Wi-Fi, that's it
• Visual conductor path animation with brush-stroke style
• Multiple time signatures: 4/4, 3/4, 4/8, 3/8, 6/8, 9/8, 12/8
• Live BPM changes sync across all connected devices
• Built on PeerClock — an open-source P2P clock sync framework

Perfect for musicians, bands, and ensembles who need synchronized timing across multiple devices without relying on cloud services.
