Besides looking good, this app does exactly what it set out to do. It’s lets you set “atomic clocks”, the radio controlled and radio synced clocks that should auto set themselves, but appear to never be able to get a signal.
On the phone, I struggled to get it to work, though others online had better experiences with earphones/headphones (big magnets, the cable acting as signal spreader) and some say even an AirPod can work.
I had better experiences with an iPad, but mostly because the speaker is larger. You may also find placing the clock on a poorly shielded Bluetooth speaker might work well also. Turning volume up all the way is needed: I think you need to hear the clicks to make sure enough signal is generated. The sound itself doesn’t really matter, it just implies that a strong enough current is being sent to move the magnet at the right frequency and can get to the antenna of the clock.
It takes a while. Be willing to wait 7-10 minutes get the sync to complete.
The app supports almost every major radio signal format for time that my various watches and clocks expect, including US, Germany, and Japan.
Very nice app! Rare to have one just do what it says it will do.
