Works well if you only need to find the phone, fails if you need alerts that you left your phone behind. If the watch is also connected to Wi-Fi, turning off Bluetooth on the phone (as a proxy for going far enough from the phone) doesn't completely sever the connection to the watch, so the watch doesn't alert that it's no longer directly connected to the phone.
Works well when I need to find my phone. A ton of weird features that I have no desire to explore.
It is super unreliable. At least once a day it goes off when I'm sitting next to my phone.
I have turned off the left phone alerts and just use it as an alternative to the Apple watch 'ping' phone
The app works, Sometimes fails to response quickly but I believe that my watch is to blame (TagHeuer Connected)
Takes too long to let me know that I don't have my phone with me.
