The desktop window

What it does. The PC is the hub: it holds the survey, talks to your controller, and hands out the walk code. It does not record — it has no GPS. Recording happens on the phone or tablet you carry.
How to use it
The strip at the top
- Walk code — the 6-digit number a walker types. Click it to copy.
- Status badge, in the order a walk goes through:
- WAITING — no device has spoken to this PC.
- ON THE LAN — a device reached the PC. That is a ping, not a walk.
- READY — a device has the walk code accepted.
- COLLECTING — points are landing. The window switches to the Map and follows the walker.
The toolbar
Dashboard, Map, Reports, Place APs, then Connect device and Settings. Help ▾ sits at the right: help (or press F1), setup wizard, browse all docs, contact support, open in browser, reload page, and about.
The Dashboard
The home screen. A row of chips shows the controller (or none (GPS only)), how many points and walks are stored, and how many APs are pinned. Below it, Connect a phone or tablet has the QR code, a copyable link and the Android download. Tablets on the LAN lists devices that have reached this PC, and Next steps lists only what is still undone — it says All set when nothing is. How HollowMap works (collapsed) has the short version and the list of supported controllers.
Opened in a browser instead of the window, the Dashboard also shows the status badge and walk code, since the strip at the top is only in the desktop window.
The tray icon
HollowMap keeps running when the window closes. Right-click the tray icon for Open HollowMap, Open in browser, Settings, Restart server, and Quit.
Troubleshooting
- The badge says ON THE LAN and stays there — the device reached the PC but has not had the walk code accepted. See Connect a device.
- Opening the recorder on the PC bounces to the Dashboard — deliberate. The PC has no GPS, so it cannot record a walk.
- The window is blank after a restart — use Help ▾ → Reload page; the server may have restarted after a settings change.
