Works as advertised

I was thinking twice about whether it would work for my g shock 3495 module square with a phone, it just works as stated. The clean simple UI / app is a great addition to my watch, definitely worth $2.

Keeping watch on the phone or iPad over the loudest speaker (you can do hearing test to see where it is loudest), and then letting watch sit on it does the job in 3-4mins.

Best 2 Bucks I Ever Spent

I have three atomic timekeeper watches and one of them is just so finicky and was driving me nuts because I couldn’t get it to synchronize. I found out about this app from another user and the very first time I used it my watch synchronized. This app is absolutely worth $2. I just wish I would have known about it sooner.

Absolutely brilliant

I moved house and my watch no longer could receive a signal to update my watch I tried a few different apps but none off them worked but this one did 100% recommended it’s worth the £1.99 I paid

FAQ

What does Clock Wave do?

Clock Wave allows you to calibrate your radio-controlled watch or clock. It transmits accurate time signals from your iPhone or iPad to your timepiece, ensuring it's always synchronized.

How does Clock Wave calibrate my watch?

To calibrate, you tap the 'Transmit' button in the app. Then, set your watch or clock to manual receive time signal mode and place it near your iPhone/iPad's speaker. The app will then transmit the accurate time.

What time signal stations does Clock Wave support?

The app covers five major longwave time signal stations worldwide: WWVB (USA), JJY (Japan), BPC (China), MSF (UK), and DCF77 (Germany). You can manually select stations if your device has specific compatibility needs.

Is Clock Wave free to use?

Yes, Clock Wave is available for free. There are no in-app purchases or advertisements mentioned in the application data.

What if my watch doesn't support a specific station?

If your radio-controlled watch or clock doesn't support a particular station (e.g., BPC or MSF), you can manually select an alternative station like JJY or DCF77 within the app's settings. You can also manually set the timezone if your device only supports a specific one.
