TwoKey: Paired Messaging

TwoKey is a messaging app for conversations that must stay between exactly two people. Before you can message someone, the two of you have to be in the same room: one phone shows a code, the other scans it. Without that step the two phones cannot open a conversation at all. There is no username to look up, no phone number to find, and no link that lets a stranger reach you. WHAT IT DOES • Pair face to face by scanning a code from the other person's screen. • Confirm you are talking to the right person by reading twelve characters aloud. They match only if nobody is in between. • Message text is never written to your phone's storage. There is no history to recover from a lost device. • Your contacts are kept, encrypted, so you do not meet again every time you close the app. • Agree how long messages live, as something both people accept. • Message text is hidden from screenshots and screen recordings, and both people are told when one is attempted. • A keyboard built into the app, so what you type never passes through a third-party keyboard or the predictive-text dictionary. • Notifications name nobody unless you choose otherwise, and never show message text. • Lock the app behind Face ID and a code of your own. • Back up your contacts, encrypted, with a recovery key only you hold. WHAT IT DOES NOT DO • It cannot stop the other person photographing the screen with another camera. Nothing can. • It cannot help if either phone is compromised. • It has not yet been independently security audited. The app says so, and we would rather say it than imply a review that has not happened. PRICING Free to download. Scanning someone's code and replying is always free; you are never asked to pay to keep talking to someone. Starting conversations of your own, by showing your code, is free for 14 days from your first pairing. After that it needs a yearly subscription: Personal, up to five conversations you started at a time, or Unlimited. If a subscription ends, nothing is deleted; the conversations you started pause until you subscribe again. PRIVACY No account. No phone number. No analytics, advertising or tracking of any kind. We cannot read your messages; the keys never leave the two phones. The camera is used only to read a pairing code.
