## What is Wave Sync Watch?

Wave Sync Watch helps synchronize compatible radio-controlled watches when tower reception is weak or unavailable.

The app generates a precise audio signal through your device speaker. When the watch is placed directly against the speaker, some radio-controlled watches can pick up the near-field signal through their receiver coil and decode the time pattern.

This is not a long-range radio transmitter. It is a close-contact speaker-based signal tool for watches that support standard radio time protocols.

Features:
  - NTP-corrected live clock
  - Manual NTP sync
  - Automatic protocol selection by region
  - Support for WWVB, DCF77, JJY40, JJY60, MSF, and BPC
  - Standard and experimental output modes
  - Live envelope preview during broadcast
  - Real-time transmitted-data inspector
  - Physical checklist before starting transmission
  - Light and dark mode
