MORE ACCURATE RESULTS • Room dimensions now follow the walls instead of the direction you were facing when the scan started, so room-mode and speaker-placement advice lines up with the real room. • Fixed the speaker-boundary (SBIR) null frequency, high-frequency roll-off in every measurement, reflection levels, and per-band reverb times. Expect treble to read flatter and bass problems to land at the right frequencies. • Each speaker is analysed separately. A subwoofer no longer drags down the flatness map or the EQ. • Room modes are only reported when the measurement actually shows them at more than one spot. A STEADIER WALK • The screen stays on during the walk, and a "Slow down" banner appears if you move too fast for a sweep. • Sweeps taken while tracking was lost, while the phone moved too far, or while the mic clipped are skipped and counted instead of becoming bad points. • If your speaker or AirPlay output changes mid-walk, measurement pauses with a warning until it comes back. CLEARER RESULTS • One 0 dB reference across every chart and export; levels are labelled dBFS. • "How is this scored?" explains the overall score and its weights. • The decay plot is labelled as modeled, heatmaps use fixed scales with real units, and the EQ exports in REW / Equalizer APO text format. • Reverb is judged against a target for your room's size, and a new reverb check tells you when the room is too live. • Metric or imperial units, Dynamic Type and VoiceOver support on the Results screens.

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.
