With more than half a million monthly users and a million installations after just three months on the market, Jott is fast becoming the must-have messaging app among teenagers, rivaling the well established WhatsApp.

Unlike other apps, Jott functions without Wi-Fi or mobile data. Instead, it uses a combination of Bluetooth and radio to allow users to send private messages to other devices within a range of 100 feet. In schools where Wi-Fi is limited, WhatsApp and Facebook Messenger rely on mobile data credit which users have to pay for. Jott allows pupils to get around Wi-Fi dead zones and stay in touch without running up bills.

The app also allows users to connect with their Instagram account and to message Instagram contacts without asking for a phone number. Just like SnapChat, Jott also offers the option of disappearing messages. To improve security the makers have installed screenshot detection which inform users if the recipient has attempted to take a permanent screenshot of the message.
