The 26 Screen FX keys

For streams and fun

Prize wheel on a screen shared in a video call

Prize wheel NEW

Type the names and spin. Hold the key to spin it by hand: the longer you hold, the longer it takes to stop. Great for picking who answers next.

Two dice picking an icebreaker question in a video call

Dice NEW

Real 3D dice that tumble, bump into each other and rock before settling. Hold the key to shake them; the more you shake, the harder they're thrown. Handy for picking a question, a topic or whose turn it is.

Applause and laugh neon signs over a slide shared in a video call

Applause & Laughs NEW

Two keys, one studio audience: applause, laughs or both, each with its own neon sign.

Drumroll reveal with a drum and confetti

Drumroll NEW

Builds up the tension, then reveals your text with confetti.

Disco ball and light beams on a live stream

A rain of bills for a sale, a donation or a milestone.

Furry critters flying across the screen

Smoke that drifts in and fades, and a camera flash across the whole screen.

For classes, meetings and presentations

Goal bars on a live stream

Goal bar NEW

A progress bar everyone sees, with −1/+1/+5 buttons on screen that only you see: they don't show up in OBS, Zoom or recordings. Stack several and drag them anywhere.

Spotlight on a few lines of code in an editor

Spotlight NEW

Dims everything but a circle of light that follows your pointer.

Drawing arrows and circles over a slide

Draw on screen NEW

Pen, highlighter, arrows and a laser that fades away. Right-click undoes.

Be right back curtain

Privacy curtain NEW

Cover your screen in one tap with a “be right back” sign, with an optional timer.

Countdown timer on a slide shared in a video call

Timer

Countdown, stopwatch or clock. Can show only on your monitor, invisible to OBS, Zoom and recordings.

News bar ad on a live stream

Ad pop-up

Your own image or message in a corner, centered or as a news bar, for sponsor shoutouts.

Also included: Click highlighter NEW — a ring on every click, so everyone can follow your mouse.

Why it's different

Most overlay tools need OBS browser sources or a heavy app running in the background. Screen FX doesn't.

⚡

Native and tiny

A single signed and notarized Swift binary, a 1.6 MB download. Apple Silicon and Intel.

🖥️

Works everywhere

It draws on your real screen, so it shows up in Zoom, Meet, classes, presentations and recordings — not just streams.

🖱️

Never in your way

The overlay is click-through. Pick the main display, all displays, or the one under your cursor. On-screen controls, like the goal bar buttons, stay private: only you see them.

🔊

Sound included

Dice, applause, drumrolls, balloon pops, fire and more come with their own sound, and every key sets its own volume. Nothing else to install.
