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
