Personally I found the best device and location tracker is to use Google maps, especially on an inherent Android device. I created a new Google account shared my devices location with that account. I then use the Google maps integration with home assistant and grabbing cookie method in order to link this new Google account with home assistant. This enables me to not give my real Google account credentials to HA.
Anyhow, I’ve tried owntracks and Life360 and this seems to be the best way that works for me. I also have my wife share her location with the same new account to track us both.
