WatchWave - Radio Signal Sync App Reviews

Would not sync using an iPhone 15 speaker, but using Apple AirPod Pro headphones it worked great. Took a few tries but now my Casio watch is set. Tuned off ear detection in Settings so the Airpods would still make noise while sitting on top of the watch. Very happy!

NIST station WWVB lost half its antennas in a storm and we lost coverage in Southern United States. This app works! I get it. 20 KHz harmonics coupled from speaker voice coil. Very clever. One small detail is that the clock time is off about 1.5 seconds slow. I work in communications and it would be really great if the program creators would add an offset function to dial the time in exactly. Just give us a setting where we could insert a number, say -1400 ms, to offset the transmitter digital c

The app is well designed functionally and aesthetically. It works for my Casio Oceanus 5701 module. I have to place it so that either the bottom speaker or the ear speaker is firing directly into the bottom of my watch. Really convenient for when you can’t access radio reception or don’t want to set it manually. It seems to use the system time, so check that’s accurate.

Got a G Shock GW-M5610U and live on the east coast where it’s difficult to receive the signal even at night near windows. Legit first time using this app, it synced in 5 min. Love it.

I live in the South Pacific and brought my group of atomic clocks so I could could keep up on times around the world. This app solved my alignment problem and saved me several hundred usd for an “old school” signal generator which seems to fail every 3-5 years. Works perfectly on one or two clocks at a time because they have to be super close to the iPad or iPhone. This is the only drawback that you can’t turn on the generator and align all the clocks on the wall.

I was able to sync my Casio G-Shock GWM-5610 and keep it accurate. I was annoyed when daylight savings time came along and my watch did not adjust the time. I checked and my watch had not been able to sync for months because of some type of interference where I live. With this app I can accurately sync the time to my multiband Casio watch whenever and wherever I am.
