User Reviews

It works, but about 2-3 seconds from the other direct sync “clocks” I have . This problem clock I have works exactly when in a separate location… but when move to an old position where it synced correctly no longer logs on. Something must have changed affecting this old location. So was hoping this app would allow me to correctly sync it periodically. But no joy😂. As said… it actually syncs this “clock” but about 2-3 seconds different from the “correct” time as shown on the app… as well as my other self syncing “clocks”. Kind of weird must say.
