Description
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 works great. Start manual sync on the watch. Put your watch up against your phone speaker, turn the volume all the way up, in a few minutes, the sync completes. It's a bit loud, so do it in a room where you can close the door.

The best radio-controlled watch app, worked superbly with my Casio G-Shock and Wave Captor watches. It has the China BPC signal emulator that is not in other apps. This is still the best rc watch app. Thank you!

The app works great so far on my Casio and Citizen Multiband 6 watches. It consistently gives a L3 signal for all my atomic watches.

Well, I decided to go VIP to have it unlocked, unfortunately I did the purchase and for some reason, still show the message Upgrade to VIP, so I got scammed and robbed??? Too bad.

Tried many times and no matter what phone or orientation I used on my watch, it doesn't work. I tried a different app and that app worked the first time.
