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.

Characteristic:
1. Supports simulation of all types of Time Wave Signal:
* China BPC
* USA WWVB
* 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.

I tried a few other apps and this one provides the loudest signal that helps my Casio watches grab the signal better and usually faster! The interface is very simple and even provides tips for each brand of watch in case you have issues. I definitely recommend this app to keep your Casio watches synced without having to face it in a certain direction or make sure there aren't trees in the way. Good job!

I seriously hought it was BS, but had to give it a try. The phone's speakers transmits a high pitch sound. I live in Hawaii, so most times I get a "No" reception. Occasionally I'll get a "Low" reception. I activated the app, the phone speakers gave a high pitch signal, and my reception went "High". After the reception the time was accurate to the second. This is great!
