Ratings and Reviews
I was doubtful of how clicking sounds from a speaker would simulate radio signals but bought the app anyway. I tried the app with a Lacrosse atomic clock that can’t receive a WWVB signal unless it was by a west facing window. It didn’t work so I was all set to give a 1 star scam rating and review.
I decided to try it again but this time I aligned the speaker with the back of the clock and turned up the iPad volume. When I looked five minutes later the signal received icon was showing on the clock and it was synchronized with the correct time, having been 12 seconds slow before.
Now I have to find how why and how this works
If you don't live close to a time signal radio station, this app is a necessity to keep your "Atomic" watch precise without having to constantly adjust it manually. It works by placing your watch (a Citizen Eco-Drive in my case) in the 'on demand reception' mode, placing it closest to the device speaker (I found the louder iPad pro to work the best), and putting the app in transmit mode. The app itself sync's to one of the worldwide time signal radio stations of your choice. Unlike trying to sync the watch to the actual time signal radio (fails about 9 in 10 times), using the app almost never fails. Kudos to the developer.
Freaking Amazing App! You are my hero!
Just bought a watch from eBay and was having trouble receiving the time signal with it. Loved the watch but not sure if there was a problem with the receiver. No way to test but to go outside at night away from the house, point north, etc., etc. Even a watch I already owned and knew worked with the signal was having trouble. Heard about JJY app on a google review of a similar watch and then hit the App Store for it, and took a guess to search for WWVB. Found this app! Less than ten minutes later, watch synchronized! Fabulous, and best $2 that I ever spent.
With Family Sharing set up, up to six family members can use this app.
