On board with Kilobat

Make a shared train link go further

Kilobat is a Mac menu-bar app that shows what each app sends and holds back what can wait. On TGV INOUI Wi-Fi on board:

  • The sign-in page. When it doesn’t open by itself, the menu bar says This Wi-Fi wants you to sign in, with Open sign-in page. Turn your VPN on again after you’ve signed in. Free
  • Why it can’t connect. When a VPN, iCloud Private Relay or custom DNS hides the sign-in page, Kilobat names the layer that broke: VPN, DNS or the network. Free
  • See what’s using it. Every app’s upload and download, live in the menu bar, so you know which one is taking the shared link. Free
  • Mark it metered. macOS treats train Wi-Fi as unlimited. Mark it Metered and Kilobat skips its own speed tests; with automatic switching, Travel blocks backups and the like on that network. Pro
  • Send later. A big upload, such as Dropbox syncing a folder, can wait until you’re on unmetered Wi-Fi again, for up to eight hours while Kilobat is open. Pro
