In 2026, quirky “reaction apps” like SlapMac and Spank App (Spank Phone) started trending on social media. These apps use device sensors to detect physical impact and trigger funny reactions such as sound effects or voice clips.
SlapMac became especially popular because it allows users to slap their MacBook and hear humorous sound reactions, creating viral videos online.
On the other hand, the Spank App focuses on smartphones, where users slap the back of their phone and hear escalating reactions depending on how hard the hit is.
Both apps are made mainly for entertainment, but they work differently and target different devices.
