In a hyper-connected society, mobile coverage is essential. Rarely is the time that happens to us, but running out of coverage still causes us some uneasiness similar to when we leave our beloved smartphone at home. For those, even without coverage, talking to their loved ones is more than a necessity, the perfect App can be FireChat . This application allows all users to chat even when there is no coverage or Wi-Fi networks available or the data rate has run out (which can also happen). The system is very similar to Bluetooth since the technology used by Firechat is still a delivery of signals between devices. This does, and here comes the trick, that the users of this application must be less than 10 meters away . However, this limitation is nothing more than anecdotal at certain times since, given that it does not require active telecommunications infrastructures, it can be extremely useful in exceptional cases such as a natural disaster or an emergency in which communications are the first thing to disappear. Those who do use Bluetooth technology to establish connections between phones in proximity is also the Jott App. In your case, it allows the distance between the mobile sending the message and the receiving mobile to be about 30 meters. This application works as a social network, allowing a user to send a message to another even without knowing her phone number. Everyone who is connected to Jott appears in our contact list. To ensure privacy , Jott has automatic message deletion and screenshot detection functionalities, as in Snapchat .
