This update is all about stability and accuracy. Thank you to everyone who reported problems — we read every review. FIXED: CRASHES • No more crash when a phone call, Siri, or an alarm interrupts a measurement, or when a Bluetooth speaker disconnects mid-walk. • No more crash at launch after updating. Saved rooms migrate automatically, and if the library ever can't be opened the app recovers instead of failing to start. • Fixed a crash opening results for some sessions. • Fixed out-of-memory crashes when generating 5.1, 7.1, and Atmos test-signal files. FIXED: "IT KEEPS PLAYING" / "THE MIC STAYS ON" • Leaving the measurement screen by any route now stops the test tones, releases the microphone, and turns off the camera. • Switching away from the app mid-walk stops the measurement cleanly and tells you, instead of silently saving a bad session. MORE ACCURATE MEASUREMENTS • Latency calibration was measuring the wrong thing. It now finds true system latency, so every impulse response is aligned correctly. • Room modes, standing-wave frequencies, and reflection distances were off by 8% due to a speed-of-sound error. Fixed. • Reverb time (RT60) is now measured from the actual decay after each sweep, not a 0.3-second window that could never capture a real room. • The 3D map, sweet spots, and problem locations are now in the same coordinates as your room and measurement points. • The frequency response chart uses a proper logarithmic axis, so bass detail is readable. • Live coverage percentage now updates as you walk. FASTER, SMOOTHER RESULTS • Results screens no longer freeze on large sessions. Heatmaps, waterfall plots, and charts render in the background. • Measuring an existing room again keeps your speaker positions and room geometry. • "Re-scan Room" and "Edit Dimensions" now edit the room instead of creating a duplicate. • Audio Routing test buttons work; External Test Signal files are more reliable. • Deleting a room also removes its files from your device.
