No account. No phone number. Nothing to sign up for. Two phones agree to talk by showing each other a code once. After that only those two phones can read what passes between them, and there is no account anywhere to leak, demand, or hand over. NOBODY CAN FIND YOU There is no directory, nowhere to search, and no address that leads to you. You start a conversation by showing someone a code in person, or by sending an invitation link that works once and expires after 24 hours. THE SERVER HAS NOTHING TO GIVE UP Messages pass through a relay holding encrypted blocks — every one exactly 8192 bytes, so size says nothing — under random names tied to no one. No user table, no record of who talks to whom. Blocks are deleted when collected, and expire after 21 days regardless. Tap the byte count under any message and see exactly what the server saw. BUILT TO STAY UNREADABLE X25519 with ML-KEM, the post-quantum standard, and the Double Ratchet, through libsignal — the audited open-source library behind them. Your text is padded to 4096 bytes before encryption, so even the ciphertext length gives nothing away. A message captured today stays unreadable when quantum computers arrive. Compare the sixty safety digits once and you know nobody came between you. If a contact's key ever changes, sending stops until you confirm. FOR THE MOMENT SOMEBODY IS HOLDING YOUR PHONE You choose two passphrases. One opens your conversations. The other opens an app that looks identical, holding ordinary, unremarkable ones. Nothing reveals which you typed: no alarm, no notification, not one second of delay. A third, optional passphrase destroys everything, then opens that same quiet app. Every conversation has a panic hold: press the name at the top and you are on the other side instantly. No button exists to give it away, and coming back needs the passphrase. The app also re-locks on its own — immediately, after a minute, five, an hour, or never. AGAINST THE CAMERA IN THE ROOM Screenshots come out blank. Screen recording and mirroring too. Captures work only where both of you allowed them: your messages sit on the other phone too, so a choice one of you makes alone protects nothing. Allow them and the other person is told the moment you take one. For a second phone pointed at your screen, camera mode opens a message only under your finger. Deniable wording bends the spelling on the way out so a photograph cannot quote you, leaving numbers, times and addresses as typed. Agreed words let one word stand for another, the meaning never reaching the screen. A watermark says which phone a leaked screenshot came from. MESSAGES THAT GO A timer per conversation: gone when you leave it, an hour, a day, a week, a month, or never. Counted from when a message is sent, not read. A ghost message is stronger. Read once, for three to thirty seconds, and then it exists on neither phone. Ghost messages never touch the disk, and a ghost photo can never be captured, whatever either of you allowed. Photos are encrypted on your phone and padded to one of five fixed sizes. NO INTERNET, NO PROBLEM Turn on nearby delivery and a message crosses the room directly — over Wi-Fi, or over the radios if there is none. It works with the internet cut off, and no third party sees the timing, the volume, or that anything was said. WHAT WE WILL NOT PRETEND Any server sees where a connection comes from. We do not log it, but that is a policy, not mathematics: use a VPN or Tor if you need to hide that you use Discrio at all. No software can stop somebody photographing your screen with a second phone. It raises the cost, not the impossibility. Forget your passphrase and your conversations are gone. Nothing is kept from which they could be rebuilt. That is the design, and the one thing that cannot be softened. Notifications say only "New message" — never who, never what — and can be turned off. 17 languages. No accounts, no analytics, no advertising, no third-party code. ## Version history (last 3 releases) ### 1.2 — 2026-09-24 A message or photo you send as a ghost now disappears from your own phone too, on the same countdown the reader sees. It used to sit there until the app was restarted. The reasoning was that the sender already knows what they wrote — true, and beside the point. What this app is built for is the moment somebody else is holding your phone, and a ghost left in your own conversation with its text intact is exactly what they would read. ### 1.1 — 2026-09-16 Shake the phone to read a conversation as it was meant — every agreed word shows its meaning at once, for six seconds, then puts itself away. The list of agreed words now asks for your passphrase. The real one shows what they mean. Any other shows something else entirely, with no error and no second chance offered. Photographs open at the size they were sent. A ghost photo closes itself when its countdown does, and screenshots of it are refused whatever either of you allowed. ### 1.0 — 2026-09-14 No release notes. ## Apps similar to Discrio | App | Rating | Price | Category | | --- | --- | --- | --- | | [ANCROM - Secure Messenger](https://appshunter.io/ios/app/ancrom-secure-messenger/id6770340118) | — | Free | Social Networking | | [Krypta ECC](https://appshunter.io/ios/app/krypta-ecc/id6754332196) | — | Free | Social Networking | | [DatChat: Social Network Plus](https://appshunter.io/ios/app/datchat-social-network-plus/id999516973) | 4.8 (944) | Free | Social Networking | | [WeHappy - Connect & Share](https://appshunter.io/ios/app/wehappy-connect-and-share/id6449167906) | 4.9 (11) | Free | Social Networking | | [Migu - Live Video Chat](https://appshunter.io/ios/app/migu-live-video-chat/id6466331416) | 1.0 (1) | Free | Social Networking | | [Keet - Private Encrypted Chat](https://appshunter.io/ios/app/keet-private-encrypted-chat/id6443880549) | 4.6 (205) | Free | Social Networking | ## More apps by Bartis Arnold - [GooMit: Find Activity Partners](https://appshunter.io/ios/app/goomit-find-activity-partners/id6764824864) All apps by Bartis Arnold: https://appshunter.io/developer/1895926755 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
