SecretR00M is a privacy-focused messaging app designed for temporary, real-time conversations. Create a room, invite others, and communicate securely while everyone is connected. Messages are protected with end-to-end encryption and are never stored. When the room ends, everything disappears. SecretR00M does not require accounts, phone numbers, or message history. The app is built for users who value control, discretion, and simplicity. Key features: • End-to-end encrypted messaging • Temporary rooms with no message storage • No accounts or sign-ups • Messages exist only during active sessions • Clean, minimal interface • Designed with privacy in mind Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://keniprimo.github.io/SecretR00M/privacy.html SecretR00M is ideal for conversations that don’t need to live forever.

WHAT'S NEW • Persistent friendships, not disposable rooms. Add a friend once with a one-shot invite code; they stay in your list under an emoji you pick for them. No more re-creating rooms every session. • Emoji identities. Every friend is represented by an emoji you choose — no photos, no phone numbers, no names to enter or leak. • Disappearing messages. Toggle a self-destruct timer per message; the message wipes from both devices after it expires. Timer duration is configurable. • End-to-end encryption everywhere. Every message is sealed on your device, unsealed only on the recipient's. The server routes but never reads. • Full UI redesign. New "instrument panel" visual language — monospaced typography, hairline borders, live 4D-tesseract signature. Light and dark modes both supported. • Signed friend requests. New cryptographic binding proofs on identity claims and lookups block the server or a man-in-the-middle from ever substituting an impostor's key. • Rebuilt server. New Go relay replaces the old Node stack: faster, per-IP rate limiting, graceful reconnects, offline mailbox for friends who are away. • Tesseract Plus (new subscription). Unlocks Tor routing, Ghost Text (message rendering that cameras can't capture), Pixel Shatter, custom timers, groups, duress PIN, and a 30-day offline mailbox. Free tier remains fully functional for direct messaging. PRIVACY We never see your name, phone number, contacts, or message contents. What the server knows about you: two public keys. That's it. Upgrading from SecretR00M: your old rooms are retired. On first launch the app generates a new identity — add your friends again with a fresh invite code and you're set. ### 1.4 — 2026-04-16 Version 1.4 — FlickerGuard Anti-Camera Text Protection SecretR00M now protects your messages from cameras, screenshots, and screen recordings with three new protection modes: Ghost Text — Messages are rendered at ultra-low contrast using color science that exploits the gap between human vision and camera sensors. Your eyes can read it on screen, but cameras and screenshots capture nothing. Uses isoluminant color shifting that JPEG compression literally destroys. Pixel Shatter — Text is split into hundreds of horizontal strips, each at a different virtual depth. Tilt your phone and the letters shatter apart. There's no single camera angle that can reconstruct the message. Both — Maximum protection. Ghost-colored text that also shatters on tilt. Additional features: Shield button in the message composer to toggle protection per-message Touch-to-reveal magnifying loupe for reading ghost text Protected input field — see the protection effect as you type iOS screen capture prevention layer for protected messages Full settings screen with live preview, adjustable contrast, color modes, background presets, character fragmentation, and background noise Protection applies equally to all participants — host and client Privacy first, as always. All protection metadata is end-to-end encrypted alongside your message content. ### 1.3 — 2026-02-25 Bug Fixes Fixed duress alert not reaching participants: When the room host was under duress, the silent warning wasn't being delivered to other participants. Now duress alerts work correctly regardless of whether you're hosting or joining a room. Fixed PIN unlock issue: Resolved a bug where the main PIN was incorrectly rejected after setting up a duress PIN. Both PINs now work as expected. ### 1.2 — 2026-02-23 Duress PIN Protection Added a "panic password" feature for users in high-risk situations. Set a secondary PIN that, when used to unlock the app, silently alerts all room participants that you may be under coercion. The alert appears as a system message, giving others a discreet warning without revealing anything suspicious on your screen. ### 1.1 — 2026-02-23 Invite Links: Share secure one-time invite links to bring others into your private room Streamlined sharing: Single-tap to copy or share invite links via any messaging app Improvements: New app icon with refreshed design Updated launch screen Improved deep link handling for smoother invite experience Enhanced Tor connection flow when joining via invite links Bug Fixes: Fixed invite link creation and validation Fixed issue where invite links wouldn't process correctly on app launch Improved connection reliability ## Apps similar to Tesseract Network | App | Rating | Price | Category | | --- | --- | --- | --- | | [Mesh Voice & Chat: bitTalk](https://appshunter.io/ios/app/mesh-voice-and-chat-bittalk/id6749445251) | 4.7 (10) | Free | Social Networking | | [twocents: Social Budgeting](https://appshunter.io/ios/app/twocents-social-budgeting/id6754617302) | 4.7 (83) | Free | Social Networking | | [Confess2Me](https://appshunter.io/ios/app/confess2me/id6752618101) | — | Free | Social Networking | | [ON Social: Fastest way to meet](https://appshunter.io/ios/app/on-social-fastest-way-to-meet/id6453477871) | — | Free | Social Networking | | [BeApp: Meet People Nearby](https://appshunter.io/ios/app/beapp-meet-people-nearby/id6740001645) | — | Free | Social Networking | | [Dionysos Social Club](https://appshunter.io/ios/app/dionysos-social-club/id6502960218) | — | Free | Social Networking | ## More apps by Kevin Kulcsar - [Road2Heaven](https://appshunter.io/ios/app/road2heaven/id6743947366) - [FIREB4LL](https://appshunter.io/ios/app/fireb4ll/id6758861661) - [PeakD4Y](https://appshunter.io/ios/app/peakd4y/id6760320337) All apps by Kevin Kulcsar: https://appshunter.io/developer/1793415655 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
