For help with placement, monitoring sessions, thresholds, alerts, event cards, the archive, the family demo or the optional city board, email [email protected] with your device model, iOS or iPadOS version, app version, the screen you were on, and the steps that reproduce the issue. Please do not send anyone else's information.
Sessions run only while the app is open in the foreground. Complete the placement guidance first, keep the device on screen, and start the session again if you left the app or locked the screen. A very short session may also end before you notice.
Watch the live X / Y / Z readout while you tap the desk: if the numbers barely move, the surface is not passing enough movement through to the device. Check that the threshold is not set too high, that the device is flat on a hard surface with no soft mat, and that the session is still running.
Raise the threshold, move the device away from fridges, washing machines, speakers and wobbling desks, and check the placement again: an overhanging edge or a soft pad makes small movements look larger. Changing the level during a session recalibrates the window, so give it a moment.
The archive keeps at most 500 events, and drill records stay separate from real events. Deleting an entry asks you to confirm and you can cancel before anything is removed. When the archive is full, the oldest entries are the ones that roll off.
The demo replays the local notification flow with a built-in script and reads no real sensor data. Notification permission is requested only when you enable the demo; if you declined, re-enable it in Settings > Notifications > DeskTremor. The demo never pushes to another device.
The board is optional and depends on Apple CloudKit. When CloudKit is unavailable, signed out or restricted, the app labels what it shows as local demo data instead of presenting it as nearby reports. Only three anonymous fields are ever written.
Use the in-app data controls to remove events, waveforms, sessions and settings. Deleting the app also removes its local records; Apple device backups are controlled by your settings and by Apple.
An alert describes sustained multi-axis movement this device read on this surface. It is not an official earthquake warning, gives no magnitude, epicenter or intensity, and should not be used to decide whether to evacuate or return.
如需放置、监测会话、阈值、提醒、事件卡、事件归档、家庭演示或可选同城看板方面的帮助，请把设备型号、iOS 或 iPadOS 版本、App 版本、出现问题的页面和复现步骤发送到 [email protected]。请不要发送他人信息。
监测只在 App 处于前台时进行。请先完成放置引导，让设备停留在屏幕上，如果中途离开 App 或锁屏，请重新开始会话。会话时长很短时，也可能在你反应过来之前就结束了。
一边轻敲桌面一边看实时 X / Y / Z 读数：如果数字几乎不动，说明桌面没有把足够的移动传到设备上。再检查阈值是否设得过高、设备是否平放在硬质桌面上而不是软垫上，以及会话是否仍在进行。
可以调高阈值，把设备挪离冰箱、洗衣机、音箱和会晃的桌子，并重新检查放置：悬空的边角或软垫都会让很小的移动显得更大。监测期间切换档位会重新校准判定窗口，请稍等片刻。
归档最多保留 500 条事件，演练记录与真实事件分开存放。删除条目时会请你确认，确认之前可以取消。归档满后，被移出的是最早的条目。
演示用内置脚本重放本地通知流程，不读取真实传感器数据。只有在你启用演示时才会请求通知权限；如果之前拒绝过，可以到「设置 > 通知 > DeskTremor」重新打开。演示不会向其他设备推送任何内容。
看板是可选的，并依赖 Apple CloudKit。当 CloudKit 不可用、未登录或受限制时，App 会把展示内容标注为本地演示数据，而不会当成附近的真实记录。看板只写入三个匿名字段。
可以在 App 的数据控制中删除事件、波形、会话与设置。删除 App 也会移除其本地记录；Apple 设备备份由你的设置与 Apple 控制。
提醒只描述这台设备在这个桌面上读到的持续多轴移动。它不是官方地震预警，不提供震级、震中或烈度，也不应用来判断是否疏散或返回。
