Works with a loudspeaker

Sync succeeded with an iPhone 6s built-in
speaker. Kudos.

A speaker with higher output is recommended for faster syncs.

WOW IT WORKS!

I recently purchased a citizen radio watch but haven’t managed to get a radio signal in 3 weeks. I live in the north east in a very dense metro so I was trying to plan an opportunity in the mountains to get it some signal. Then i found about about this app on Reddit and it really works! The first couple of times it didn’t cast a strong enough signal from my phone but I set my watch infront of my iPad and it got the signal. Brilliant!

FAQ

What does WatchWave do?

WatchWave simulates radio signals from six different global stations. This allows you to calibrate your radio-controlled watches and clocks, ensuring they are perfectly synchronized with atomic time, regardless of your location.

How does WatchWave calibrate my watch?

The app uses its proprietary 'WATCHWAVE SIMULATION TECHNOLOGY' to generate sound waves that mimic the signals broadcast by radio stations like WWVB, MSF, DCF77, BPC, and JJY. You hold your device near your watch or clock, and it receives these simulated signals to adjust its time.

Is WatchWave free to use?

Yes, WatchWave is completely free to use. The app does not contain any advertisements and offers all its features without any cost to the user.

What types of watches and clocks are supported?

The app supports a wide range of radio-controlled devices, including Multi-Band 2, 3, 4, 5, and 6 radio watches or clocks. The WaveTurbo feature even allows for synchronization with 2-Band watches that might otherwise be restricted by signal areas.

Can I use WatchWave if I'm not in a region with radio signal coverage?

Absolutely. The core functionality of WatchWave, particularly the WaveTurbo feature, is designed to overcome geographical signal limitations. It simulates the radio signals, allowing you to calibrate your devices anywhere in the world.
