The same three ideas — a zone, a schedule, an alert — configured very differently depending on what you are watching. Each page gives the actual setup rather than a feature list.
Geoblip is deliberately general. A zone, a device, a schedule, and an alert covers most of what people want to monitor — the pages above are the setups we see most often, not a list of what is supported.
If you are working out whether it fits, the geofencing explainer covers what these systems can and cannot do, and the geofence builder lets you draw a zone and see its real dimensions before signing up for anything.
