常见问题 FAQFrequently Asked Questions

请远离金属物体、磁铁和电子设备。在空旷处缓慢将手机画"8"字形来校准传感器，通常可以恢复精度。 Move away from metal objects, magnets, and electronic devices. In an open area, slowly move your phone in a figure-8 pattern to calibrate the sensor — this usually restores accuracy.

磁北是地磁场指向，真北是地理北极方向。两者之间的差角称为磁偏角，会因地区不同而有所差异。开启位置权限后，Compass 会自动补偿磁偏角。 Magnetic north is the direction the Earth's magnetic field points, while true north points to the geographic North Pole. The angle between them is called magnetic declination, which varies by location. When location permission is granted, Compass automatically compensates for declination.

位置权限仅用于获取当前地区的磁偏角数据，从而提供更精准的真北方向。位置数据不会被收集或上传。 Location permission is used solely to retrieve the local magnetic declination value for accurate true north. Location data is never collected or uploaded.

可以。Sleep 支持后台播放，锁屏后音频会继续播放，并可通过控制中心暂停。 Yes. Sleep supports background audio playback. After locking the screen, audio continues and can be paused from the Control Center.

在播放界面点击定时器图标，选择 15/30/45/60 分钟，到时后音频将自动淡出停止。 Tap the timer icon on the playback screen and choose 15, 30, 45, or 60 minutes. The audio will automatically fade out and stop when the timer ends.

可以。所有内置音景均包含在应用安装包中，无需联网即可使用。 Yes. All built-in soundscapes are bundled with the app — no internet connection required.
