About this app

Attention: There are a lot of people this application requests, so it's made. But there is no environment that a maker tests. Operation guaranteed won't be done.

Note
It can not correspond to the atomic clock. Please adjust the NPC time with other apps.
Correspondence in this application is not planned.
We will receive more emails requesting radio clocks from other countries, but since you can not create it without materials, please attach the clear material you need.

How to use
Place headphone speakers by the atomic radio clock's internal antenna, with the volume as high as possible before it starts to distort. Or, place the clock’s internal radio antenna as close as possible to the smartphone speaker. Again, with the volume as high as possible before it starts to distort. When time sync receive mode is active, the clock will sync within 2 to 3 minutes.

Ratings and reviews

I really like this app. It works great with my radio controlled digital clock. I do have a little tip for anyone who sees this... To get the most accurate time, consider adjusting your phone system time to most accurately match the atomic (NIST) time. Then sync the time to your radio controlled clock with this app. Your clock should then match NIST time down to the second when sync is complete. Just be sure to set your phone's time setting back to automatic when done.

LOVE this free app! I live in Santa Cruz, CA, (right on the west coast) so it's often really difficult/impossible to find a stable, atomic signal. This FREE app which I downloaded a few months ago has been working perfectly, so I can now set my atomic watches & wall clock whenever I want. It's great, I highly recommend it! Edit; One thing I do have to say, however, it's a bit of a battery drain. At least on my device it is (I have a newer Samsung S20). So just be aware of that.

I was a bit surprised, but it *worked*. I have had radio-synchronized Casio watches for years, and while they don't get the signal every night (I live on the East Coast, far away from thel Colorado WWVB broadcast), they did pretty well. I recently got a Citizen watch that has been less capable in picking up the signal, so it was about 5 seconds fast. I found this app via Google, installed it on my Samsung tablet, and followed the instructions by boosting the tablet's volume and putting the watch into receive mode alongside the tablet's speakers at about 6:45 p.m. well indoors. The app started emitting clicks and pops, and about 10 minutes later, the watch showed that it had received and synchronized the time, and it is now exactly matched to the tablet (and, presumably the Internet time).
