Bitfocus Companion Module

How to install (Dev Module)

  1. Download the .zip above, extract it, and move the kuma-companion/ folder somewhere permanent (e.g. ~/companion-modules/kuma-companion/)
  2. Open the Companion launcher, click the ⚙ cog icon (top-right) → Advanced Settings
  3. In the Developer section click Select and choose the folder containing kuma-companion/ (e.g. ~/companion-modules/), then toggle Enable Developer Modules on
  4. Close settings, click Launch GUI, add a new connection and search for KUMA Timer

Companion watches the dev folder live — you can update module files without restarting.

First Launch

KUMA Timer is available as a Microsoft Store app (Windows), Apple App Store (macOS, coming soon) and as a direct download for both platforms. Store versions install without any security warnings and update automatically.

macOS — Apple App Store COMING SOON

The easiest way to install KUMA Timer on macOS — no Gatekeeper warnings, no right-click tricks, automatic updates.

 Get it on App Store  SOON
Why £5.99?
KUMA Timer is an indie project. The App Store price covers Apple's developer programme fee ($99/year) and helps keep development going. If you can, installing through the App Store is the best way to support the project — it means a lot. ☕
macOS — Direct Download
macOS Gatekeeper dialog
  1. When the "KUMA Timer Not Opened" dialog appears — click Done
  2. Open System Settings → Privacy & Security
  3. Scroll down — you'll see "KUMA Timer was blocked"
  4. Click Open Anyway and confirm with your password

Alternative: right-click the app → Open → Open in the dialog that appears.

☕ Why does this warning appear?
Removing it requires an Apple Developer certificate ($99/year) + a notarisation fee. KUMA Timer is free — every coffee goes directly towards covering these costs so future versions can open without any warnings.

Windows — Microsoft Store RECOMMENDED

Install directly from the Microsoft Store — no security dialogs, no warnings, automatic updates.

 Get it on Microsoft Store  SOON
Manual installer (.exe) — if you prefer the direct download, Windows Smart App Control or SmartScreen may block the unsigned installer:
Windows Smart App Control dialog
  1. Click OK to dismiss the dialog
  2. Open Windows Security → App & browser control
  3. Click Smart App Control settings → set to Off
  4. Run the installer again — it will launch normally

If you see "Windows protected your PC" (SmartScreen) instead — click More info → Run anyway.

You can re-enable Smart App Control after installation.

Network Access — Firewall Dialog

On first launch KUMA Timer will ask for permission to accept incoming network connections — this is required for OSC, Web Mirror, Web Controller and NDI.

🍎 macOS
A dialog will appear: "Do you want the application 'KUMA Timer' to accept incoming network connections?"
Click Allow.
🪟 Windows
Windows Defender Firewall will ask to allow KUMA Timer on private/public networks.
Check Private networks and click Allow access.
Minimum screen resolution — 1280 × 768. On very small screens the control panel may extend beyond the visible area. If the title bar is hidden: right-click the taskbar icon → Move, then use the arrow keys.
Anonymous usage statistics — on first launch KUMA Timer will ask whether you'd like to share anonymous usage data. If you agree, the app sends: Hardware ID (anonymised identifier derived from your network card), OS name & version, and app version. Nothing else — no names, no files, no location, no IP address stored.

Participation is entirely optional. You can opt in or opt out at any time in Settings → Misc → Privacy.
Why no code signing? Apple charges $99/year for a developer certificate that removes the Gatekeeper warning on macOS. Microsoft's EV certificate for SmartScreen costs even more. KUMA Timer is a free, independent tool — if you find it useful and want to help cover these costs (or just say thanks), buying me a coffee goes a long way. ☕
