meshO Manager
Run the whole event from one laptop.
Event timing and management software. Install it on one computer; everyone else — the download desk, registration, commentators, arena TVs, spectators’ phones — opens it in a browser. With or without radio controls.
Free
Windows · macOS · Linux

One install
No copies to keep in sync and no separate database. Every other device just opens a web page.
Everyone sees it live
A download, a radio punch, a status change — every connected device updates the moment it happens.
Roles split across people
Downloads, missing punches, late entries and commentary at once, from different devices.
No internet needed
A local network is enough on the day. The internet is only for downloading updates.
How it works
One server, any number of browsers
One Windows, Mac or Linux computer
