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.

I cranked up the volume to 11, kicked off a manual receive then placed my g-shock with the back of the watch facing the speaker. Hit start and a few minutes later time was adjusted. My watches usually automatically sync at night but manually they almost always fail. I had one that hasn't updated and with the recent time change it was an hour off so I got this app. World the first time for me. Thanks

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!
