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

Excellent app! Does exactly what it's intended to do, and makes an excellent backup when the WWVB signal is too weak or compromised. While it may not be 100% to the precise second (it uses your phone clock which may be off by a few milliseconds) according to NIST or USNO atomic time systems, it still does the job VERY well. The key is to have the phone volume all the way up and hold the phone's speaker as close as possible to the antenna system of the time piece you wish to sync. Works well!!!

it worked on an old alarm clock I haven't been able to sync since I moved into my new house almost 4 years ago. I'm going to test it on my g shock next but I'm going to be honest and say I have no idea how the speaker on my phone emulated the radio waves from fort Collins but I appreciate the fact someone figured out how to do this.

This app actually synced my radio controlled clock, that's amazing! Now i can keep my clock synced when WWVB is too weak or off the air or if I'm at the other side of the world. But i do have one request, however... can you please make the DST (Daylight Savings Time) automatic? The actual WWVB signal does the DST automatically. It's inconvenient when this setting needs to be manually set.
