Developer Tonino Catapano has created an app that causes a MacBook to make "moaning" or screaming sounds when it is slapped. Called 'SlapMac', the app costs $7 (around ₹664), as per its website. In a Reddit post, Catapano said, "As of now, it made me $5,000 (around ₹4.7 lakh) revenue in 3 days. 2026 is so unhinged."
