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.

Took some fiddling to find proper positioning of the phone speaker against the watch (the only headphones I have didn't work at all), but then it just worked! Pure magic of an app. I live quite a bit outside the tower's coverage area and in a large city with lots of tall buildings around and tons of RF noise so getting my watch to sync has been a constant pain in the back. Not anymore. Thank you very much!

This is awesome and WORKS!!!!!! (Used a Tab Active and the clock was set after two minutes). Tried changing timezones and it set everytime with no issues. Too bad I live in PT and there is no WEST timezone. Perhaps an option to put an offset would be easier to do than listing a lot of timezones. Even if on a paid, ad-less version, for instance!! I'd buy it instantly!!

Worked as indicated in the instructions. On my Citizen watch, I cannot properly receive the DCF77 signal from Mainflingen. First I used an atomic clock app to verify that my phone time was set to NTP, it was showing lag of 1.494 seconds but by going to the date & time settings in the phone and toggling automatic time set off then on, the phone updated the time and the atomic clock app showed a lag of only 0.190 seconds, good enough! With a rooted phone, you can get apps that will automatically sync with NTP, but for un-rooted phones you can only sync with your providers time (AFAIK).
