GPSTrackServices needs a lot of work! When you try to set an alert on your phone it lets you set everything but the save button is off the bottom of the screen. If you use an iPad in landscape, everything appears in a pop up window including the save or delete buttons. There is supposed to be a support button in the menu to explain how to use GPSTrackServices (user guide), but someone forgot to add it to the menu. I stumbled across it in “If your car is stolen” on my phone, but it doesn’t appear on my iPad, however, the first page of the user guide does appear, but none of the other pages. GPSTrackServices is not at all intuitive and without the user guide a new user is lost. The best way to use it is to open GPSTrackServices on both your phone and iPad. You can display the user guide on your phone and edit the alerts on the iPad, but you can’t display the guide on the iPad or edit alerts on the phone.
