Clock Wave

According to NIST, one of the antennas for WWVB was damaged in a windstorm. I didn’t know that until today and the unreliability of time synchronization was driving me nuts. Happily, this app gives me some ability to keep my watch close to accurate until the antenna is replaced. Yes, it does work, and it’s really clever. Made my day!

As many, I was skeptical this would work, but living in a sketchy place for atomic clock synchronization I gave it a chance. It worked on my new G-Shock GW-5000U-1JF. Bless the company that delivers on what you pay for.

I have no idea why but this app does exactly what it claims to do. my atomic clock between solar activity, and Florida thunderstorms had not updated in a couple of weeks. I took a chance on this app and it actually works. The one thing to be aware of is that the speaker must be directly over the antenna in order for it to work correctly. synchronizing my clock during summer just got a whole lot easier. Well worth the money and I’m glad I purchased it.

Ran for 10-20 minutes in different positions near two different model Marathon Atomic Clocks without success.

I love my Casio watch, but for three weeks I could never sync it mainly because I live in a half basement apartment And I get very little sleep literally the hours I sleep are the hours that it would sync, but I couldn’t leave it anywhere else, but this app works perfect for two dollars. You can’t beat it.!!!

Works exactly as described with no bloat. I used this to sync my wall clock that wasn’t able to receive the WWVB signal over the air. Laid my phone on the face of the clock and it synced after one full transmission completed (indicated by the tics moving across the screen on the app)

I tried with Citizen, Casio, and Seiko radio wave controlled watches. None of them works. Do more reach on the Internet. Don't trust those YouTube videos review. They got paid to lie. Sound wave is totally different than radio wave. You can't make your iphone to produce radio wave. Apple will be in deep trouble with FCC. If their phone can do that, it will create a lot of radio frequency interference.

Used the app to synchronize my atomic watch. I used my Bluetooth speaker and it worked. Don’t turn the volume on the speaker too high, or the signal will clip/distort and fail the sync. But as long as you can hear it so can the watch. Just keep it close to the speaker. Took about 8 minutes the first time.

As the title states, works perfectly. Does require an internet connection for the synchronization of the time. Once that’s done, I followed the directions and was able to sync my Casio watch!

Recently got a Citizen eco watch with atomic time and could never get reception where I live. Tried a few free apps with no success, however, tried this app and first time it worked after five minutes.
