Common questions
Why does every result show an uncertainty band?
Phone sensors and camera or AR conditions vary by device and scene. HangLevel keeps the uncertainty visible so a result is not mistaken for millimeter precision.
What if AR or the camera is unavailable?
Use the manual measure path. For proof, the app provides a clearly labeled simulator or no-camera fallback and keeps checklist and export actions available.
How do I remove a project and its proof files?
Delete the project from Projects. Its measurements, plans, inspection records, and locally stored proof images are removed together after confirmation.
Can I share a report?
Open the report and use the iOS share sheet. The receiving app controls any copy after sharing.

常见问题
为什么每个结果都有误差区间？
不同设备和现场的传感器、相机与 AR 条件不同。挂画尺保留误差说明，避免把结果误解为毫米级精度。
AR 或相机不可用怎么办？
可以使用手动测距流程。留证流程也提供明确标注的模拟器或无相机备用路径，清单和导出仍然可用。
怎样删除项目和留证照片？
在“项目”中删除项目并确认。其量测、方案、验收记录和本地留证图片会一起删除。
可以分享报告吗？
打开报告后使用 iOS 分享面板。分享后的副本由接收 App 控制。
