Terrible. It doesn't function well for what it does. Wants to use maximum battery power and tries to force your location on. I want to track others, not be tracked myself, but they don't allow it willingly. Try to delete locations and it claims there's a connection issue when there's not and therefore won't delete them. Which is awful because for free you can only get notifications for two locations. The free version is bad and they have the audacity to ask you to pay for more features
