Hunter's comment

Walkietooth is an Android app and it establishes a full communication between two Android devices.
It lets them communicate and it is better than two walkie talkies.
You can also use it as a baby monitor or maybe for an easy communication on motorcycle.
It is not easy to communicate while doing some extreme sports,you can use Walkietooth for an easy communication during your extreme sports activities.
