Signa
The presentation toolkit for professionals. Control slides from your iPhone, spotlight key ideas, annotate in real time — all over your local Wi-Fi.
Requires macOS 14 or later
What it does
Every tool a presenter needs.
Laser Pointer
Control a glowing laser pointer on your Mac screen from your iPhone — with trail and glow, visible in any presentation software.
iPhone Remote
Swipe to advance slides. See the current slide, next-slide preview, and presenter notes — all on your iPhone screen.
Spotlight
Dim the screen and draw attention to exactly what matters with a customizable spotlight circle.
Magnifier
Zoom into any part of your screen in real time. Up to 4× magnification with a clean, circular lens overlay.
Annotations
Draw freehand, add arrows, shapes, and highlights directly on screen. Auto-fades cleanly after a few seconds.
Whiteboard
Instantly switch to a white or black canvas for live sketching. Drawings persist across slides until cleared.
Break Timer
Show a full-screen countdown during breaks. Custom message, chime, and style — so your audience always knows when to return.
Click Effects
Ripple, Burst, Shockwave, or Comet — elegant visual feedback on every click, visible in screen recordings and Zoom.
How it works
Up and running in seconds.
Launch Signa on your Mac
Signa appears in your menu bar and starts a local WebSocket server automatically on your Wi-Fi network.
Open the Signa iPhone app
The iPhone app discovers your Mac over Bonjour. Tap once to connect — no IP addresses, no pairing codes.
Present with confidence
Swipe to advance slides, drag to move the laser pointer, and use hotkeys for spotlight and annotations.
Privacy
No servers. No accounts.
Just your local network.
Signa communicates entirely within your LAN via WebSocket. Nothing is sent to the internet. No analytics, no tracking, no account required. Works in conference rooms, on aircraft, and in corporate environments where external connectivity is restricted.
Pricing
Buy once. Own it forever.
