• 0.9.9 August 2026 Latest

  New

  • Native call UI on iOS — incoming and active calls now use the system lock-screen experience and Dynamic Island.
  • Video calls — camera feed is encrypted and travels the same sealed path as everything else.
  • Front/back camera toggle during a video call, without interrupting the connection.
  • Wake-on-call — when someone calls and your screen is off, the system wakes and rings without requiring the app to be open. Requires Wake when closed to be enabled.
  • Missed call notification — shown locally on the device when a call ended while the app was unreachable.
  • @username search — if someone has claimed a handle and set themselves as findable, you can start a new invite from their @name without asking them for a link.

  Improved

  • Message delivery is meaningfully faster — the relay connection is reused across sends rather than re-established each time.
  • In-app notifications — messages from other conversations show as an in-app banner; if you are already in that chat, nothing appears.
  • System banners suppressed while the app is open — the in-app banner handles foreground alerts instead.
  • Delivery ticks — single tick when the relay confirms, double ticks when the other side has seen the message. Encrypted inside the session.
  • Presence gradient in the chat header transitions smoothly between states: settling, live, and network error.
  • New messages blur-fade in rather than appearing instantly.
  • Reaction chips use frosted glass and overlap the message corner.

  Fixed

  • Calls failed silently when encryption was active. Audio path rebuilt from the ground up.
  • Some messages were not received when both users were backgrounded at the same time.
  • Back button in the chat toolbar lost its circular glass treatment. Restored.
  • Header pill resized when the typing indicator appeared. Now holds a fixed height.
  • Emoji reactions overflowed the picker boundary.
• 0.9.5 June 2026

  New

  • Group chats — add people you already have as 1:1 contacts. No Horus group server. History stays on-device.
  • Voice notes — recorded locally, sealed in the transcript, delivered over the same path as text.
  • File sharing — any file type, size-limited by what the encrypted path can carry.
  • Emoji reactions — long-press a message to react. Reactions travel inside the encrypted session.
  • App Lock — optional biometric or passcode gate on the app UI. Off by default.
  • Nearby pairing over Bluetooth — stand next to someone, match a short code, skip the QR step.

  Improved

  • Tor bootstrap is faster on cold start — directory state cached more aggressively between launches.
  • Outbox flushes in the correct order when the path comes back up after being offline.
  • QR scanner is more tolerant of low light and angled scans.
  • Android call alerts now use the system high-priority channel on all tested versions.

  Fixed

  • First message after accept was sometimes lost if the creator was briefly offline during the handshake window. Pre-accept buffer now flushes correctly.
  • Large photos caused a memory spike before sealing. Now resized and compressed before entering the encryption pipeline.
  • Accepting an invite a second time after dismissal no longer creates a duplicate contact.
• 0.9.0 March 2026

  New

  • Dark mode — follows the system or can be forced.
  • Optional @ handle — claim a username so people who know it can send a new invite without a link.
  • Invite expiry controls — set how long an unused invite stays valid.
  • Wake when closed — opt-in push wake. A content-free ping only; no message preview reaches the push host.
  • Stay connected — keeps the path alive while the app is backgrounded.
  • Photo messages — inline previews in the chat, compressed and sealed like text.

  Improved

  • Pairing over a remote link retries internally on brief circuit interruptions.
  • History sealed at rest using the device keystore / Keychain.
  • Scroll performance in long conversations.

  Fixed

  • Mic permission was requested at startup on some Android devices — now requested only at first call.
  • Unread badge count showed stale numbers after switching tabs.
• 0.8.0 November 2025

  New

  • Voice calls — encrypted, over the same sealed path as messages.
  • Timed messages — set a TTL; the other side's copy wipes itself after the countdown.
  • Mute conversations — muted chats still deliver, just do not banner.
  • Message editing — changes travel inside the encrypted session; edit history is not retained.
  • Reply threading — quote a specific message; the reference is encrypted along with the reply.

  Improved

  • Tor embedded library updated — cold-start time reduced on most devices.
  • Invite links are shorter and easier to share without truncation.

  Fixed

  • Keyboard overlap on iPhone models with a home bar sometimes hid the composer.
  • App crashed on Android 12 when the system revoked the Bluetooth permission mid-session.
• 0.7.0 August 2025

  New

  • Delete for everyone — asks all parties to wipe the message on their device. Not a server delete; the request is itself an encrypted message.
  • Archive conversations — hides from the main list without deleting history or stopping delivery.
  • Pin conversations to the top of the inbox.
  • iOS and Android now share one protocol implementation — conversations are cross-platform from this release.

  Improved

  • Old session keys wiped from memory sooner after advancing the ratchet.
  • Scroll-to-bottom button in long conversations.
  • Timestamps show relative time for recent messages.
• 0.5.0 May 2025

  Initial release

  • 1:1 encrypted messaging. No phone number. No account. Keys stay on the device.
  • Invite-based pairing via link or QR. Invites are one-time use and expire.
  • Double Ratchet with a post-quantum hybrid step in the invite handshake.
  • Offline outbox — messages queue on-device and send when the path is available.
  • Local delivery receipts — sent / delivered / read ticks, encrypted inside the session.
  • iOS 16+ and Android 10+ supported.

Versions before 0.5.0 were internal only. Questions go to Support.
