Why it can be useful

This program can be useful in the situations that we will describe.

As the developers say, this app can be successfully used by bikers during the long trip in the column. In this case, all participants of the column, who are within 50 – 100 meters from each other, can communicate if they connected the Bluetooth headset to their smartphone (it is more convenient).
If we use the wireless headset, this app can be useful in the noisy places (on the construction site etc.). In this case, the interlocutors can communicate without having to shout if being 50 meters apart. No fee will be taken from your phone account, because only the Bluetooth signal will be used for the conversation.
People who have small children can turn two smartphones into the baby monitor. They will only need to activate the app on both devices, and then they will always be aware of the child’s activity.

The ideas of using the Bluetooth Intercom app for Android are not limited to the abovementioned ones. Everything depends on your fantasy and your needs. Maybe you will find other application of this program based on your needs.
