Can iBeacon work without an app?

Hello there,
We are trying to figure out if iBeacon could work without an app. In other words, can iBeacon send a signal to an IOS device, using bluetooth?

Based on what we've been reading, user must have an app already installed, in order to receive a notification via iBeacon.

Please advice.
