Radio Wave Sync is a free utility app developed by 宁 金 for iPhone. This app is designed to solve the problem of radio controlled watches not being able to receive radio waves from time signal stations. With Radio Wave Sync, you can simulate the timing signal and easily calibrate the time on your watch.

To use the app, simply adjust the volume of your iPhone to the maximum and switch your radio controlled watch to manual wave receiving mode. Then, click the "start" button and place your watch near the iPhone speakers. The synchronization process typically takes 3-10 minutes, so please be patient.

It is recommended to use the app in a quiet environment to avoid signal interference. Additionally, make sure to adjust the volume of your mobile phone to the maximum for optimal performance.

Radio Wave Sync supports simulation of all types of Time Wave Signals, including BPC (China), WWVB (USA), JJY40/JJY60 (Japan), DCF77 (Germany), and MSF (British). The app also offers a unique "Beast Mode" that provides higher frequency simulation signals for faster syncing.
