I really like your service. I have an idea that would make the notifications system more usefull.
I have a tracker set up in my car and have set a geofence around my home. When the car leaves the geofence, I receive an email. This means that when I leave home with the car, I receive an email while driving. It is not necessary to notify me that the car is moving when I'm the person who is in the car. I have a smartphone that is also set up in GPS-Trace, so all data is available to determine if I'm in the car.
Add the possibility to make notification rules so that the user can make Excel-like formulas using all data available in the user account. This way I can make a formula that only sends an email when the car is moving and my smartphone isn't near the car at the same time.
Thanks for your time.
