About this app

I have a Casio G-Series radio watch, but it is always unable to receive radio waves from time signal station, so I started to write an application to solve this problem.

After some research, I finally wrote this application, which can perfectly simulate the timing signal and happily calibrate the time.

Usage method:
1. Adjust the volume of phone to the maximum.
2. Switch the radio controlled watch / clock to manual wave receiving mode.
3. Click the "start" button.
4. Place the watch / clock near the phone speakers.
5. The synchronization process generally takes 3-10 minutes, please wait patiently.

Matters needing attention:
1. Please try to use the software in a quiet environment to avoid signal interference.
2. The volume of the mobile phone must be adjusted to the maximum. It's too small and the effect is not good.

1. Supports simulation of all types of Time Wave Signal:
* China BPC
* Japan JJY40 / JJY60
* Germany DCF77
* British MSF
2. The unique "Beast Mode" provides higher frequency simulation signals and faster sync.

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.
