What’s new

Version 1.1.1 · Updated July 21, 2026

What's New in v1.1.1 - More reliable auto-reconnect. The iPhone now connects directly to the tablet's fixed IP and keeps knocking every 3 seconds while disconnected, automatically pushing its new IP after a Wi-Fi/network change — no manual reconnect needed. (Legacy UDP discovery removed.) - Dropped-connection detection. The iPhone now sends periodic heartbeat and keep-alive packets, so a lost connection (screen lock, network drop, app backgrounded, or being force-quit) is detected quickly and recovery starts on its own — instead of freezing on the last frame. - Smoother split-screen / CarPlay handling. Mirroring briefly pauses during layout changes (e.g. entering/leaving split screen) and resumes cleanly, preventing a stuck or black stream. - Accurate touch orientation. Remote mouse control now follows how the phone is physically held (portrait / landscape / upside-down), with anti-jitter smoothing so taps no longer drop out when the device is at a borderline angle.
