Radio time for real watches
Wave Sync Watch
Set radio-controlled watches with the built-in speaker on your iPhone or iPad.

Designed for the awkward cases
When tower reception fails, use the speaker beside the watch.
Wave Sync Watch generates the longwave time patterns that radio-controlled watches expect, then couples them through the phone speaker as a local magnetic field.
The app keeps the workflow narrow: choose the signal, place the watch near the speaker, and transmit during the watch receive mode.
Coverage
Built for common atomic watch regions.
