Even with paid version, doesn’t work

Unfortunately no matter how I position the phone, or use of the “beast mode,” I cannot get a successful sync with my brand new Citizen tsuki yomi watch. I only give it two stars because it seems like some people can get it to work - but it’s junk for me.

Never worked for me but other app did.

Tried it every way possible. iPhone speaker, Bluetooth speaker, wired speaker, headphones every possible position. Wasted well over an hour. It never worked.
Maybe this works if you pay to unlock their beast mode but their free version will not work for my watch.

I tried a different paid App with initials C.W. and it worked first try with Casio 5161 moduled watch 12 o’clock position against iPhone 16 speaker.

No sound

It worked until the moment I paid for it. Now it doesn't work because it makes no sound. Feedback link in App Store leads nowhere.

Doesn’t Work.

Nothing I try works. The Casio simply will not sync. I put it in a dead silent room and full volume with the phone speaker 1mm from the watch. ERR. Always ERR.

Great app! Cannot restore purchase.

Really cool tool, I use it with my Casio, however I’m a little bummed I can’t turn on beast mode because I unable to restore my purchase.

FAQ

What does Radio Wave Sync do?

Radio Wave Sync is designed to help you synchronize radio-controlled watches, especially those that have trouble receiving time signals. It works by simulating the necessary time signal waves that your watch needs to calibrate itself.

How do I use Radio Wave Sync to sync my watch?

To use the app, first set your iPhone/iPad volume to maximum. Then, switch your radio-controlled watch to manual wave receiving mode. Place your watch near the device's speakers and tap the 'start' button. The synchronization process typically takes between 3 to 10 minutes.

What time signal standards does the app support?

The application supports simulation of several international time wave signals, including China (BPC), USA (WWVB), Japan (JJY40/JJY60), Germany (DCF77), and the British (MSF) signals. It also features a 'Beast Mode' for higher frequency simulation and faster syncing.

Is this app free to use?

The application is free to download and use, but it does offer in-app purchases. It also displays ads. For the best results, ensure your device's volume is at its maximum and try to use the software in a quiet environment to minimize signal interference.

What devices is Radio Wave Sync compatible with?

The application is designed to work with iPhones and iPads. Users are advised to ensure their device's volume is set to the maximum for optimal performance when simulating time signals for their radio-controlled watches.
