Radio Wave Sync

I used it once to sync a clock and was happy to review it with 5* as the clock locked in a signal and set the time; what I did not notice is that is actually copied the Japan time, so I’m not sure it was because the app or just simply it found somehow the Japan time beacon. However, when I tried to use it the second time it would not let me use any function unless I paid for the pro version. I think this is against Apple’s app store policies; the app should maintain the basic functions and not be time-locked. There was no mention in the app description of a mandated trial…

Nice app, however i purchased premium package and still got Japanese commercials in the app.

I synced my Junghans Mega Solar to the Japanese time signal JJY 60 to test it, and the watch now reports that the last received signal was indeed JJY 60 so it works! Really cool! Device was an iPhone SE. I don’t have much use for it because I can receive both the German and the UK signal where I live, and the Junghans app also works, but it’s good to see that this works as well, and can imitate different stations! It would be nice to add an option to send a manually set time. This also allows easier checking to see if it indeed receives the time from the app.

In Beast mode = Boost mode even faster. The app's DCF77 was easily succesfull in Netherlands. My clock frustratingly did not respond by itself in day time, so i am happy that this app could trigger it well.

4分钟左右对时成功，不错👌

两快卡西欧手表完美对波，其中有一块十几年的表一直对不上，后来换了新电池就对上了，「首先对波一定要找安静的地方，无论开不开狂暴都可以对的上，我的手机是iPhone12就把表正面放在前置摄像头位置的扬声器上，如果不成功就在试几次，一定成功」

历经两周对又对 圆于执着准又准

好用，新疆地区比较远接受不了秋波，一直用这个软件挺好用！

一点开始就让购买

真的太感动了！手表放柜子里大半年，也不知道什么时候没电了，放阳台一星期都没成功收波，看了网上教程搜索电波app，第一个就是这款，本想试试看，结果一次成功！太意外了！惊喜！感谢开发者大佬！！
