Just when you thought the wonderful world of digital messaging couldn’t get any more rich and layered, along comes another app to prove there are more ideas in the digital sphere than can be contained within the average web user’s philosophy… Just don’t call Kibo a messaging app. It is in fact an iOS keyboard app for sending hidden messages within other messaging apps’ messages — be that WhatsApp or iMessage or Facebook or whatever.
Why would you want to do that? Perhaps your parents or siblings are snooping around on your phone. Or you’re worried about message notifications flashing up on your lock screen and being read by the prying eyes of colleagues or your S.O. Or you want to make your friends have to download another app just to read the beer emoji you’re sending them… But it’s probably most useful as an added privacy layer — like an anti-shoulder surfing screen protector for your messaging activity.
“Kibo solves the problem of users’ privacy protection when exchanging messages containing any secrets or private information,” is how the co-founders explain their mission. “People commonly believe that no-one can intercept their private messaging; however, their very personal messages are often seen by their friends, colleagues, and passers-by. So, we are aiming to provide a means of sending and receiving messages in a way that no-one except the sender and the recipient will be able to see and read them.”
How it works
1. In any IM, type a message you want to hide into the IM’s input field using the Kibo keyboard, and then tap ‘Lock’ button on the right of the space bar.
2. Once the ‘Lock’ button is tapped, your message is replaced with a random innocent-looking phrase.
3. After that you can send the message by tapping ’Send’. This message will appear in the chat visible for everyone; however, only you and your contact will have an access to the hidden message inside.
4. To read the hidden message, simply copy it to the system clipboard. It can be done by double tapping or long tapping on the visible message. If there is a hidden part inside, it will be shown in a popup view inside of the Kibo keyboard.
Now be at ease! Even if your smartphone falls into the wrong hands, all your communications will be hidden under common everyday phrases.
