- $5,000 in 3 days
A guy named tonnoz posted a simple Instagram reel – reviewing a free GitHub project that makes ridiculous sounds when you slap a MacBook.
It went viral.
Comments were all “WHERE IS THE APP” “I NEED THIS” over and over.
So I built it.
48 hours later, SlapMac was live – a $5 app with 130+ sound clips across seven voice packs.
Slap your MacBook and it screams, moans, or yells “ULTRA COMBO!” depending on the pack 
He skipped the Mac App Store entirely and self-distributed from his own website…
no approval process, I am self distributing. Apple would have killed all the momentum
$5,000 in the first 3 days.
10 days in, that number hit $20,700 
About half of all downloads convert to paid. He’s since raised the price to $7 and added a “USB Moaner” mode – plug in a USB device and your MacBook reacts.
tonnoz is a software engineer, but he vibe-coded SlapMac in 2 days with AI and now…
I’m reconsidering my whole career.
The app concept already existed as a free GitHub project. tonnoz just spotted the demand in the comments and shipped a polished version in 48 hours.
Your turn: scan trending content for “I NEED THIS” comments, then move fast
