It took a few tries of positioning each of them but I was able to sync up my 3 Casio watches. After syncing the first one and reading the reviews, I knew what I was getting into in terms of payment and how many times I'd be adjusting the position of my other watches, I opted to pay upfront. Easy to use interface. The noises are high pitched and can be annoying but the app worked for me.

Honestly I Feel like I Discovered Fire after using this App. I just purchased an Atomic Timekeeping Clock and it wouldn't sync up no matter how much effort I put into it, been staying up all night into the morning and gave up. Started reading about WIFI clocks and GPS timekeeping clocks until I found a post on WWVB signal Emulator app, downloaded the app and just a minute my new wall clock was set but 2 seconds ahead my other Atomic Clock app. Does not let you choose a NIST Internet Time Server.

It works. Just make sure your device is set up correctly. My citizen watch was in a drawer for months. I charged it and ran this app. The date was correct, but the time was off. Turns out I had to reset the reference points of my watch hands. Once the hands were reset, I ran the app again, and it worked great.
