Companion app
Definition
The smartphone application that pairs with an IoT or wearable device, caches recent sensor data locally, and relays data to the cloud backend. The companion app on a seized smartphone is often the fastest acquisition target because it holds a local copy of recent device data without requiring a cloud production order.
