This is going to be very convenient:
Beacon-triggered Suggested Apps work slightly differently than GPS-triggered ones. The app in question does need to be installed on your device already to be suggested on the lock screen, when in proximity to a beacon. If the app uses the Core Location framework to monitor for beacon regions, it’s capable of detecting beacons even if it’s shut down completely. You’ll see the app icon in the bottom left corner and will be able to launch it immediately.
