If you are someone who types a furious text message, only to reconsider and edit it before hitting ‘send,’ you may be in trouble.

The Beam Messenger app shows everything another person is typing in a text message as they type it.

This means that if your friend has the app, they could see the keys you press, including corrections and everything you choose not to send.

The Californian firm behind the free Android app claim it is ‘a first of its kind true real-time communications app’ that more closely mimics the way people to chat in person.

For example, it lets people interject or comment in real-time, without having to wait for the other person to hit send.

And, if the recipient already knows a story that the sender is typing, they can tell them so they don’t waste time finishing the text.

Elsewhere, the app also means people can have conversations without ever hitting send, making them secure because no data is ever transferred and stored on a network.

But, it is not known how the app tracks what is being typed and how much it stores on its own servers and MailOnline has contacted the firm for more information.

The Toronto-based developers added there is no delay between typing and seeing the words appear in the message window.

It calls this ‘beaming in’, and said it gives users the ability to ‘interrupt, interject, comment, and the like’.

‘While you are texting inside a bubble, without breaking, you are allowed to backtrack and jump forward at will.

‘Also you may delete the whole text altogether, gone from both devices in true real time fashion.’

An iOS app is 'coming soon.'
