How it works

800 readings per second. Zero lag.

Your MacBook has a hidden accelerometer. SlapSound reads it in real time via IOKit HID. When you physically hit your laptop, it detects the exact impact force and plays a sound. The harder you slap, the louder and higher-pitched it gets.

No microphone. No camera. Pure physics.

Sound Packs

6 built-in sounds. Or make your own.

New

Combos. Like a fighting game.

Slap rapidly and build combos. The counter escalates with every hit. Hit milestones and achievement banners fly across your screen.

Speech & Text

Make your Mac talk. Or type.

Switch to Speech mode and your Mac speaks custom text aloud on every slap. Pick from built-in voices, type any sentence, or choose from 16 quick phrases. Or use Type Text mode to auto-type full sentences into any app on impact.

Tony Stark Mode

Say "Jarvis, are you there."

One toggle transforms your MacBook into J.A.R.V.I.S. Every slap plays a sci-fi beep. Double-clap your laptop or say the voice command — it opens Terminal with Claude Code and plays the Iron Man soundtrack. Complete with animated arc reactor.

Triggers

Double-clap your MacBook, or say "Jarvis are you there" out loud. Both open Terminal, launch Claude Code, and play the Iron Man theme. Voice recognition runs locally on-device.

FAQ

How do I get the download after paying?
You'll receive a download link immediately after payment via the confirmation page and email receipt.
Which Macs work?
Apple Silicon MacBooks with M1 Pro or newer. These have the built-in accelerometer that SlapSound reads. The base M1, Mac Mini, Mac Studio, and Intel Macs don't have it.
Will it damage my MacBook?
No. The accelerometer detects vibration from a light tap. You don't need to hit hard. A firm tap on the side or trackpad area is enough.
What's Tony Stark Mode?
It replaces all slap sounds with J.A.R.V.I.S. sci-fi beeps. Double-clap or say "Jarvis are you there" to open Terminal with Claude Code and play the Iron Man theme. Voice recognition runs locally.
Can I add my own sounds?
Yes. Record up to 4 seconds from your mic or upload any MP3/WAV file. Your custom sound persists across sessions.
Can I get a refund?
Yes. Email contact@agaro.ai within 7 days for a full refund.
Is it on the App Store?
No. Accelerometer access requires running outside the macOS sandbox. SlapSound is distributed as a signed, Apple-notarized DMG directly from agaro.ai.
