About Signal Setter: Radio Watches
Your radio-controlled watch or clock sets itself from a time station: WWVB in the US, JJY in Japan, DCF77 in Germany, MSF in the UK. Indoors, abroad or out of range, it never hears one. Signal Setter sends the station's time signal from your phone, and most radio-controlled watches and clocks can pick it up and set themselves. Reception depends on the model, so hold the watch close to the phone's speaker or to wired earphones.
PICK THE CITY, NOT THE STATION
Choose the city your watch is set to. Signal Setter picks the station a watch set to that city listens for. You can still pick any station yourself, including JJY on 40 or 60 kHz.
THE TIME IT SENDS IS RIGHT
The time comes from a network time server, corrected for your phone's own clock, and every minute of the code starts exactly on the minute. The app shows how far your phone's clock was off. Each station's own time zone and summer-time rules are applied, so your watch adds its own offset correctly. Without a connection it falls back to the phone's clock and tells you.
LOCAL TIME FOR WATCHES FROM JAPAN
A watch sold in Japan that only receives JJY always shows Japan time, wherever you are. Turn on "Send my local time" and it sets itself to the time where you are instead.
SEE THE SIGNAL AS IT GOES OUT
The session screen shows the time the signal is sending, every second of the minute's code as it plays, and the status of each minute of the session.
HOW TO PLACE YOUR WATCH
A short guide shows where the antenna usually sits and how to hold the phone's bottom speaker against it. Volume all the way up; the app will not start below full volume, because the watch picks up only a faint radio echo of the sound.
ONE PRICE
Pay once. No subscription, no ads, no account, no tracking. The only network request asks a public time server for the time.
GOOD TO KNOW
• Works with many radio-controlled watches and clocks. Reception depends on the model, where its antenna sits and nearby interference, so some watches never pick it up this way.
• Put the watch into its receive mode first. Most finish within 3 to 10 minutes.
• Use the phone's speaker or wired earphones. Bluetooth audio rarely works.
• The tone is high-pitched and plays at full volume. Keep the phone away from your ears.
