Thanks for giving the app a try! If you have any trouble syncing, make sure your watch is in manual reception mode (RC/RCV), turn your iPhone volume up, and place the watch’s antenna area—usually around 10 or 12 o’clock—close to the bottom speaker of your iPhone. Also, please select a station that matches your watch’s city or time zone. Feel free to contact me through the app if you need any help.
