Feature dump

Also, it does these things

Menu bar only

No dock icon. No window. Lurks silently like a small angry pet.

Volume scales with force

Gentle tap? Whisper. Full slap? Full volume. Physics, but stupid.

Adjustable sensitivity

From "earthquake detector" to "needs a running start". You decide.

Cooldown timer

Prevents meltdowns during rapid slap sessions. Sound dignity preserved.

USB Moaner

Coming Soon

Plug or unplug a USB device. It moans. You're welcome.

Launch at login

Always ready. Always listening. Sleep with one eye open, Mac.

Slap counter

Tracks your lifetime slaps. Global high score pending. Be ready.

Onboarding

A polite welcome flow before the chaos begins. We're not monsters.

Tuning panel

Dial in your slap

Two sliders. Two decisions. Set a vibe somewhere between "concerned librarian" and "ring announcer". This preview is decorative — the real ones live in the menu bar.

Nerdy tech details

Wildly overengineered slap detection

Five concurrent accelerometer algorithms vote on whether what just happened was, in fact, a slap. Because one algorithm is for cowards.

High-Pass Filter A1

Strips out gravity so we only see the impacts — not your hand resting on the trackpad.

STA/LTA Ratio A2

Compares short-term vs long-term averages at three timescales. Borrowed from seismology, used for vengeance.

CUSUM A3

Detects sudden shifts in acceleration. Good at catching slaps that ramp in from a sneaky angle.

Kurtosis A4

4th statistical moment — finds sharp spikes against a calm baseline. Math, doing math things.

Peak / MAD A5

Median Absolute Deviation outlier detection. The bouncer at the door of the slap algorithm club.

Quorum vote

When enough of the five algorithms agree → sound plays. Otherwise, you were just being weird.

Frequently asked

Questions, answered

Wait, is SlapDash a security app?
No. It's a therapy app. For your laptop.
Will I void my MacBook warranty?
Probably not. We're not lawyers, though, so apply judgment proportional to the value of the object you are about to strike.
Does it work on Intel Macs?
No. M1 Pro or better only. The accelerometer plumbing we need just isn't there.
Can I add my own sounds?
Yes! Coming in v1.5. Record anything: your voice, your dog, your manager during standup.
Does it drain my battery?
Barely. Less than your existential dread, less than one Chrome tab.
Will it trigger during normal typing?
No. It only fires on sharp impacts. That's what the five algorithms are for — they agree on what counts as a real slap.
Do you offer refunds?
Yes. If the app doesn't work on your supported M1/M2/M3 MacBook or you are not satisfied, please reach out to us within 14 days of purchase at shubhamsingh.course@gmail.com with your payment details, and we will issue a full refund.
Wait… is it really just ₹69?
Yes, a single one-time payment of ₹69 gives you lifetime access and all future updates. No subscriptions, no ads, and no hidden fees. Just pay, download, and start enjoying the app.
Is there a Windows version?
No. Windows users deserve their own suffering.
